esp-protocols's Issues

Timeout and RTS/CTS vs DTR config on LILYGO® TTGO T-SIM7000G (IDFGH-8630)

Dear community/Espressif!

I am trying to get esp-modem to work with my board, and I am a bit confused by the configuration.
When I tried TinyGSM (which works), I did not have to set these pins (or at least PIN_DTR is not used), but here i have to set RTC/CTS.

As far as I can see, no such pins are designated on the board, is that because it doesn't have HW flow control?
https://www.aliexpress.com/item/4000571249574.html?spm=a2g0o.9042311.0.0.31624c4dHiqssj

Either way it seems like the SIM7000G chip should be supported by this library, so I am not sure why it doesn't work.
I think I have set all pins correctly and feel that I have almost tried everything.
Yes, I have yelled at the card, as required, but to no avail. :-)

I have actually also tried to contact the card through UART using esp-idf-uart (see test()), but I am not succeeding there either, so it feels like there is something that I am missing. I send to it, but I get nothing (or zero length) in response.

As for trying esp-modem:
esp_modem_new_dev(ESP_MODEM_DCE_SIM7000, &dte_config, &dce_config, esp_netif)
succeeds but then running
esp_modem_get_signal_quality(dce, &rssi, &ber)
fails with ESP_ERR_TIMEOUT.

Now I'd like to be frank and admit that I am by no means an UART-expert, so it is quite possible that this is a very dumb question, but perhaps someone can point me in the right direction?

This works (TinyGSM, Arduino):
https://github.com/nicklasb/PoCs/blob/main/sms_power/SMS_power.ino

But this doesn't (adapted esp-idf esp-modem example, basically):
https://github.com/nicklasb/Controller/blob/master/components/sdp/gsm/gsm_init.c

(yeah, I have tried all kinds of powering up sequences)
Kind regards, Nicklas

esp_websocket_client does not allow users to include bundled CA certificates (IDFGH-7519)

I would like to use the bundled CA certificates in TLS WebSocket. The current code does not include esp_transport_ssl_crt_bundle_attach() in the code. other protocol clients, such as esp_http_client, have a member of function pointer to pass to esp_transport_ssl_crt_bundle_attach().

esp_websocket_client should do the same.

esp_modem - cant exit CMUX on BG96 (IDFGH-7954)

Hi,
esp_modem example works fine to enter CMUX on BG96, but i am having problem to exit CMUX and switch to command mode.
For some reason my BG96 is not responding on close DLCI0 command.

E (25623) cmux_example: Failed to configure COMMAND_MODE command mode... exiting

Maybe i am missing something. This is code i am using to switch CMUX->COMMAND mode:

    if (dce->set_mode(esp_modem::modem_mode::COMMAND_MODE)) {
        std::cout << "Modem has correctly entered COMMAND_MODE mode" << std::endl;
    } else {
        ESP_LOGE(TAG, "Failed to configure COMMAND_MODE command mode... exiting");
        return;
    }

Thanks

Feature request: mDNS: Add reverse lookup (IDFGH-7941)

Currently, the mDNS component / library doesn't seem to support reverse lookup.

i.e. I get no reply to dig -p 5353 -x <myip> @224.0.0.251

Could this be added?

Enter CMUX, Leave CMUX, Enter CMUX again (IDFGH-8551)

Hi,

how about enter CMUX mode, leave it, and enter it again ?

should work ?
i tested it on a SIM7070 and it seems not working.

more Control over CMUX virtual Channels (IDFGH-8559)

the Issue
#167
was about enter CMUX and leave CMUX.

but this was not the right Question. Or at least not getting to the point too much.

if we enter CMUX Mode we can have up to 5 Virtual Channels according to CMUX Spec.
as i understood, ESP-Modem does establish 2 channels, 1 AT Channel, and one Data Channel.

but now +PPP disconnect comes in as a URC, then this cannel is in command mode.
so we now have 2 Channels in Command mode.

... how to get more info about each channel ?
... how to switch this channel again into Data Mode ?

Command Timeouts (IDFGH-8185)

This is somewhat related to #66

From testing and from the BG96/95 modem data sheet require longer timeouts.

set_radio_state/AT+CFUN= upto 15s
set_pdp_context/AT+CGACT= upto 150s

I have from testing been seeing both of these commands timing out when using the default 300ms.

It would also be useful if the esp_modem_at function had a custom timeout parameter.

See BG95&BG77_AT_Commands_Manual.pdf pages 27 and 134.

About HW Flow Control (IDFGH-7281)

Hello:

if i want to use ESP_MODEM_FLOW_CONTROL_HW.

the Scenario would be (in my Opinion, but i might be wrong)

Connect to the Modem with ESP_MODEM_FLOW_CONTROL_NONE
issue a esp_modem_set_flow_control(dce, 2, 2)
Disconnect
Reconnect to the Modem with ESP_MODEM_FLOW_CONTROL_HW

how do i achieve this ?

another way would be:

Connect to the Modem with ESP_MODEM_FLOW_CONTROL_NONE
issue a esp_modem_set_flow_control(dce, 2, 2)
change FlowControl from ESP_MODEM_FLOW_CONTROL_NONE --> ESP_MODEM_FLOW_CONTROL_HW

Literature Reading:
SIM7070_SIM7080_SIM7090 Series_AT Command Manual_V1.05.pdf
Sections about Flow Control.

Error while building project with dependency `esp_websocket_client==0.0.2` (IDFGH-7986)

Hi. I'm using ESP-IDF v5.0-dev-4547-gfde4afc67a and I have installed esp_websocket_client (latest version 0.0.2) via dependency manager. When I try to build project I'm getting error:

.../managed_components/espressif__esp_websocket_client/include/esp_websocket_client.h:16:10: fatal error: esp_event.h: No such file or directory
   16 | #include "esp_event.h"
      |          ^~~~~~~~~~~~~
compilation terminated.
HINT: Please check if you've specified all component dependencies with 'idf_component_register(REQUIRES ...)'.

I have check that in 6e4e4fa esp_event has been added to REQUIRES in CMakeLists.txt but new package version with the latest changes is not published to IDF Component Registry yet.

Please make the new version of esp_websocket_client and push it to the Component Registry so we can use esp_websocket_client in our projects.

@suren-gabrielyan-espressif sorry for tag but maybe you can publish the new version of package?

Thanks in advance.
Cheers.

Question about get_network_attachment_state (IDFGH-7892)

Hello,

if I am in CMUX Mode, and sending Data over the Data Channel.
and i issue say a "get_network_attachment_state" ?

will it issue the AT Command, wait for the Response, and then Continue with the Data Transmission ?

OR does it issue the AT Command, continue the Data Transmission, and then get the Response ?

Bug while changing modem mode from "data" to "command" (IDFGH-7502)

When my BG95-M3 modem is in data mode, if I try to move to command mode with api esp_modem_set_mode(dce, ESP_MODEM_MODE_COMMAND), then I can the send AT commands, but the esp_modem still thinks it is in data mode, so if I try to move back to data mode, it will fail...

After investigating, it seems device->set_mode(modem_mode::COMMAND_MODE) returns false at

esp-protocols/components/esp_modem/src/esp_modem_dce.cpp

Lines 34 to 36 in 2a4e684

    
           if (!device->set_mode(modem_mode::COMMAND_MODE)) { 
        
               return false; 
        
           }

which explain why internal mode is not changed (see:

esp-protocols/components/esp_modem/src/esp_modem_dce.cpp

Line 46 in 2a4e684

mode = m;

)

"CMUX: Protocol mismatch: Missed leading SOF, recovering..." warning in esp_modem (IDFGH-8102)

Hello,
I am facing an issue with the "esp_modem" component. I am getting a warning " CMUX: Protocol mismatch: Missed leading SOF, recovering..." and the success rate of connection after this warning is 60%, 40% of times it does not connect. I have tried increasing the rx tx buffer, but still no luck. And, even if connection happens, I get "Protocol Recovered" log very very rarely.

P.S. I am on the latest commit.

Why isn't there a DTE config for this example like the pppos _client example, I can't find where to set my TX and RX pins for the modem. I'm assuming this is the reason the modem isn't responding to any commands.
Pls help me with a fix or how to correctly configure this example.

Thanks,

AT+COPS? on Quectel BG96/BG95 (IDFGH-7770)

Reading the operator name using the esp_modem_get_operator_name with a BG95 and BG96 returns the following value.

"Vodafone",9

The modules have factory default configuration.

It is still very useful to know the access technology, preferred fix would ideally include this. e.g. esp_modem_get_operator_name(esp_modem_dce_t *dce_wrap, char *p_name, int* act)

Our current work around currently is to strip the double quotes and parse the act code.

	/* access technology */
	*p_act_out   = -1;
	char* p_last = strrchr(p_name, ',') + 1;
	if (p_last != NULL) {
		int act    = (int)strtol(p_last, NULL, 0);
		*p_act_out = act;
	}

	/* operator name */
	char operator_without_quotes[CELLULAR_OPERATOR_NAME_LENGTH] = {'\0'};
	ESP_LOGD(TAG, "name=%s", p_name);
	char* p_tmp = strtok(p_name, "\"");
	strncpy(operator_without_quotes, p_tmp, CELLULAR_OPERATOR_NAME_LENGTH);
	ESP_LOGD(TAG, "fixed name=%s", operator_without_quotes);
	strncpy(p_name, operator_without_quotes, CELLULAR_OPERATOR_NAME_LENGTH);

esp_websocket_client is not able to use the global CA store (IDFGH-7589)

I experience problems with using the websocket client with the global CA store.
The global CA store has been enabled in sdkconfig.

I generate my websocket client config like this:

    esp_websocket_client_config_t ws_cfg = {
        .uri = url.data(),
        .task_stack = 4*1024,
        .subprotocol = "ocpp1.6",
        .pingpong_timeout_sec = 20,
        .use_global_ca_store = use_global_ca_store,
        .skip_cert_common_name_check = skip_cert_common_name_check
    };

    if (!cert.empty())
    {
        ws_cfg.cert_pem = cert.data();
        ws_cfg.cert_len = cert.size();
    }

And I get to see error messages like this:

W (13330) WEBSOCKET_CLIENT esp_websocket_client.c:416 esp_websocket_client_init(): `reconnect_timeout_ms` is not set, or it is less than or equal to zero, using default time out 10000 (milliseconds)

I'm suspecting the global_cacert is NULL message, I'm missing the crt_bundle_attach function pointer as seen in the http client and mqtt client.

Should I try to replicate the crt_bundle_attach functionality in the websocket client (and pull-request)?

Memory usage esp_modem (IDFGH-7716)

Is it normal that the library uses 1,25 MB of ram?
I've tried to narrow it a bit down, but unfortunately wasn't able to find the source of the memory usage.

Once esp_modem_new is added to the code the app uses at startup, even before executing esp_modem_new, 1,25MB more ram.
Without esp_modem_new: heap_caps_get_free_size(MALLOC_CAP_DEFAULT) = 4.367.500
With esp_modem_new: heap_caps_get_free_size(MALLOC_CAP_DEFAULT) = 3.056.596

BUG: The `ModuleIf` and `CommandableIf` do not define `virtual` destructors (IDFGH-6677)

In the following snippet, the ModuleIf abstract class defines an interface from which the GenericModule and other implementations derive. However, it does not define a virtual destructor. This is a bug that makes it impossible to destroy the derived object via a base class pointer.

Move documentation to esp-docs and docs.espressif.com (IDFGH-7119)

Currently component documentation is built with Sphinx and hosted on Github Pages.
For consistency with other Espressif projects (both visual style and location) we should try to use esp-docs for building the docs and docs.espressif.com for hosting.
esp-modbus project docs can be used as an example.

Error handling in esp_websocket_client_send_with_opcode() (IDFGH-8053)

Hi, looking at line 1004/1005 of esp_websocket_client.c it strikes me that there might be an error situation not correctly reflected in the the return value of esp_websocket_client_send_with_opcode() (see my comment in the snippet):

        wlen = esp_transport_ws_send_raw(client->transport, current_opcode, (char *)client->tx_buffer, need_write,
                                        (timeout==portMAX_DELAY)? -1 : timeout * portTICK_PERIOD_MS);
        if (wlen < 0 || (wlen == 0 && need_write != 0)) {
            ret = wlen;  /* <--- BvH HERE */
            ESP_LOGE(TAG, "Network error: esp_transport_write() returned %d, errno=%d", ret, errno);
            esp_websocket_free_buf(client, true);
            esp_websocket_client_abort_connection(client);
            goto unlock_and_return;
        }

When 0 is returned from esp_transport_ws_send_raw() while there was data to send (need_write != 0), the return value is set to 0, which is also ESP_OK. If and only if the transport layer can indeed return 0 in this case, I would suggest:

ret = (wlen < 0) ? wlen : ESP_FAIL;

Before filing a pull request, I would like to know if I am right or if there is more to this...

Thanks for the great components BTW !

Feature request: add support for LTE-M PSM & eDRX modes to save energy (IDFGH-7548)

It would be great if esp-modem would support LTE-M PSM and eDRX features, so that we could build low-power but connected devices for IoT.

Do you plan to implement such features in the (near) future?

Modem Console Sample crashing if CONFIG_COMPILER_CXX_EXCEPTIONS is not set (IDFGH-8128)

Suggestion for custom commands (IDFGH-7621)

I am currently implementing the modem protocol on a SIM7070, and in my use case I would like for it to use the modems built in feature to check received APN on network connection, however this is not available in the library. I have been trying to add a custom command, but I am having some trouble with it. Therefore it would be nice if the library exposed a simple "custom command" that sends a desired string as a command, and simply returns the received data in a string, something like:

char return_string[50];
esp_modem_send_custom_command(dce, "AT+CGNAPN", &return_string);

Which would return for example "+CGNAPN: 1,telenor.iot".

This would make running a few custom commands very easy, at the expense of the user creating his own custom code to deal with the results.

PPP Events (IDFGH-7883)

We are testing reconnection handling on PPP and having issues detecting connection losses.

When the device disconnects we can observe esp-netif_lwip-ppp: Connection lost info log message however no status event is fired. It looks like internally the PPP disconnect is detected but not propagated.

We are able to trigger connection losses by using a faraday cage and we are fortunate enough that our MVNO offer a sim reconnection facility via a portal.

We are subscribing to the PPP status events using the following.

esp_event_handler_register(NETIF_PPP_STATUS, ESP_EVENT_ANY_ID, ppp_event_handler, NULL);

CONFIG_LWIP_PPP_NOTIFY_PHASE_SUPPORT is set to y

We do not wish to use MQTT or other app state to determine disconnect logic.

How to retry PPP on failure? (IDFGH-7471)

I'm using a SIM7600 modem and I'm largely following the pattern for setup and retry set by the AP to PPPoS example (note: the pppos_client example has no retry logic at all that I can see).

When the modem disconnects, I see:

Disconnect event
Logging indicating I've put the modem in command, then data mode
User interrupted event from the PPP event handler

And then nothing. No disconnect bit, no connect bit, no IP events, nothing.

If it helps I can try to make a minimal repro example but I wonder if some documentation could be added for how this is meant to work?

It seems like the value in NETIF is null (or very close to null for esp_netif->ip_info_old) if I log the pointer address (outside range 0x3fxxxxxx - 0x6xxxxxxx like the docs suggest.

    esp_netif_ip_info_t *ip_info = esp_netif->ip_info;
    esp_netif_ip_info_t *ip_info_old = esp_netif->ip_info_old;

I was on version 0.1.12 of the esp_modem component and switched between 0.1.18 and 0.1.12 to see if it might be fixed in the newer component with no luck.

I also tried checking out previous versions of the IDF master branch that I know was working flawlessly for me ~2 weeks before with

cd $IDF_PATH
git fetch
git checkout [commit_id]
git pull
git submodule update --init --recursive

and I still got the same issue. I also tried checking out v5.0 as the last merge was 5th of July (at this point) which should have worked for me but it didn't.

I also needed to add esp_event esp_netif to the esp_modem's dependencies for it to compile.

What did I mess up?
Did I not checkout correctly?
Is there a bug?
What can I do to help?

Please let me know, I will gladly supply more information!
Thanks for making epic products and a great framework!

Unable to add PPP support for other modems (IDFGH-8466)

So I've got this FiPy I've wanted to try and hook up using the pppos examples, I've tried some older versions of the pppos-client example and gotten the IP connected where it reports back the IP address, but then I get stuck with DNS lookup failed err=202 res=0x0 and couldn't find a way past it.

So I wanted to try this newest version, and I've not really found how to add another DCE configuration here, and simply changing the pins with the BG96 gives me signal failed with 263, switching to the generic one gives me a stack-overflow error.

I also tried this example: https://github.com/N5GEH/n5geh.devices.iot_wa_aio but again I ran into the previous dns error when trying to connect to MQTT or HTTP

Strange Echo on SIM7070 (IDFGH-8499)

static functions (IDFGH-8694)

I just noticed that more functions has been set as static functions esp_modem_command_library.cpp. That will prevent reusability of esp_modem::dce_commands functions when a new device is added, for example: generic_command, generic_get_string

Using the asio component in esp-idf v5.0-beta1-720-gda9a78ebfc is not possible (IDFGH-8515) (IDFGH-8516)

Answers checklist.

I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.0-beta1-720-gda9a78ebfc

Operating System used.

Linux

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

No response

What is the expected behavior?

I expect that the asio component is available to be used by the build system, including the header and source code from asio itself.

What is the actual behavior?

The folder managed_components/espressif__asio/asio/ is empty and idf.py build reports that the registered include directory is not a directory, see build logs below.

Steps to reproduce.

Create a simple c++ project
Add asio dependency via idf.py add-dependency espressif/asio^1.0.2 as described on https://components.espressif.com/components/espressif/asio
idf.py build

Unable to use the CMUX example (with BG96) (IDFGH-7328)

Hi everyone,

I have tried to make the simple_cmux_client example work, but that is not successful. The log is (with log set as verbose):

As the problem seems to come from the line (below), I have also tried to separate both actions. From:

esp-protocols/components/esp_modem/examples/simple_cmux_client/main/simple_cmux_client_main.cpp

Line 90 in 38149c8

    
           if (dce->set_mode(esp_modem::modem_mode::CMUX_MODE) && dce->set_mode(esp_modem::modem_mode::DATA_MODE)) {

to:

bool cmux_mode = dce->set_mode(esp_modem::modem_mode::CMUX_MODE);
ESP_LOGD(TAG, "set_mode in CMUX : %d", cmux_mode);
bool data_mode = dce->set_mode(esp_modem::modem_mode::DATA_MODE);
ESP_LOGD(TAG, "set_mode in DATA : %d", data_mode);

if (cmux_mode && data_mode) {

In this case, the log is:

So the problem seems to appear during the second action, but the return code of the first action is strange. Regarding the example, it seems to me that there is a problem with the creation of SIM800 & SIM7600 object (line 83 & 75). Would it be more like dte instead of uart_dte?
In the esp_modem library, I have seen that the data mode is done with the command ATD*99## (here), while in the documentation of the BG96, it indicates ATD*99# (like for sim8xx).

I have tested the PPPoS example, which works with a small fix (EXAMPLE_MODEM_UART_EVENT_TASK_STACK_SIZE set to 3072). Without that, I have a stack overflow in uart_task.

A test board, I use a Wemos D1 R32 with a ESP32-S3-WROOM-1 module and a BG96 modem (RAK 2011). As toolchain, I use the PlaformIO with custom platform to support the ESP-IDF v4.4 (https://github.com/jonathandreyer/platform-espressif32). In my case, it is the release v4.4.1.

Does somebody have an idea or have tested this CMUX example?

Best regards,

Jonathan Dreyer

Add support for CMUX mode in C api (IDFGH-7447)

CMUX does not seem to be supported in C api: https://github.com/espressif/esp-protocols/blob/master/components/esp_modem/include/esp_modem_c_api_types.h#L38-L42

Would it be possible to add support for CMUX in C api too?

About the problem of executing AT command when the buffer is full in CMUX mode (IDFGH-7581)

Hello, in the CMUX mode, the SOC is receiving network data (the buffer is full, and the network data is still being received), and then sending the AT command will affect the network data. So I'm thinking is it necessary to add mutex locks in data mode and command mode? The command mode can only be executed after the reception is completed in the data mode.

Disable CMUX when it is no longer required (IDFGH-7372)

Hi everyone,

Does it possible to disable the CMUX after the usage? My idea is to activate the CMUX when the use of PPP is necessary and disable it after the PPP mode is no longer required. I ask that because I have tried with the following code (at the end of the simple_cmux_example), but it is not working.

if (dce->set_mode(esp_modem::modem_mode::COMMAND_MODE)) {
    std::cout << "Modem has correctly entered command mode" << std::endl;
} else {
    ESP_LOGE(TAG, "Failed to configure desired mode... exiting");
    return;
}

Best regards,

Jonathan Dreyer
