Handling URCs with binary data

I currently experimenting with a Bluetooth low energy modem and your module.
Much is to my likeing.

However, I have to deal with URCs of this form (having a counted number of binary bytes following the first line):

2024/01/27 21:08:15 r: "+QBLERECV:0,4A414E5A000000000000000000000101,6\r\n\x01\0x2\r\r\x00\xff"

I think this can not be handled out of the box right now. I noticed your interrest is not in handling data,
but neverthesless an extenion like this might be useful:

    r := regexp.MustCompile(`^+QBLERECV:0,[0-9a-FA-F]{32},(?P<dtlen>[0-9]+)`)
   datahandler := func(info string, data []byte) {
	 ...
    }
    modem.AddDataIndication(r, datahandler)

what do you think?

How to get SMS metadata

Hi, I want to get some metadata from SMS, like timestamp.

Currenly, MessageHandle only pass number and message. How to get other information?

	g.StartMessageRx(
		func(number, message string) {
			log.Printf("%s: %s\n", number, message)
		},
		func(err error) {
			log.Printf("err: %v\n", err)
		})

Unable get ERROR from USSD

I try to run a USSD code that my carrier not supported. But, It still return success (first line with OK), then second line is +CME ERROR. That error never return as error in Command() function. You can try to use USSD example and run any code that not support, the result will be the same as expected.

w: AT+CUSD=1,\"AA584C3602\",15\r\n,
r: \r\nOK\r\n,
r: \r\n+CME ERROR: service option not supported\r\n,

How to install ?

Hi,
how am I supposed to install this ?
when I try to make a go get -u https://github.com/warthog618/modem it doesn't work.

How to send USSD and wait for response

I want to send USSD code to monitor account balancer. Currently, I have to convert *101# to 7bit package as AA182C3602. Then, send in CUSD command +CUSD=1,"AA182C3602",15. The next step to do is call AddIndication with +CUSD, then decode the response from 7bit to UTF-8 string.

How to make it more simple? 😄

gsm7.Pack7BitUSSD was not just related to SMS, but USSD too. So it should live in an another package?

[BUG] AT+COPS reset

Hi,
I am trying to select network manually using the command
+COPS?
+COPS: 0,0, "", ,7 //got reply

+COPS=2
AT+COPS=2 //got reply

But then, when I try to fetch my network configurations again using the command:
+COPS?

I get this (without //got reply):
+COPS: 0 //got reply

I am able to use this command correctly using python atcom package. Any ideas where it went wrong?
I am using https://github.com/warthog618/modem/blob/master/cmd/modeminfo/modeminfo.go as base with /dev/ttyUSB0 as my device and commands +CIMI,+CSQ etc. works absolutely fine.

Can't connect to HUAWEI modem

Previously, I successfully connected to the Huawei 12d1:1506 modem. I am currently trying to connect to another Huawei device with the same vid/pid, but it failed.

However, when using gammu-smsd, the software can still connect and receive messages.

I have attached AT log information, and device information taken from the lsusb command.
Can you help me?, Thank you.

Data communication

Hello, i have looked at your library and have been sucessfull in sending SMS', but how would one communicate data, e.g. UDP packets?
Is this supported?

Thanks

[Question] Commands without 'AT' prefix

Hi,
first of all thanks for sharing this great module.
I would like to know your opinion about the following situation.

When using the at package to communicate with a modem, which is your suggested way of sending raw data to the modem itself? Example: I issue the command to send data over UDP and, after its execution, the modem listens for a message. Which is a legit way of sending that message to the modem?

I added a commandOption to exclude the 'AT' prefix from the command, such that I am able to send command without 'AT' prefix when I need it.
The reason why I did that is that at package manages lots of things (e.g. escape characters, catching the modem response) which are perhaps already setup into at configuration and which I should duplicate to achieve the same results.

I think that sending data without 'AT' prefix is out of the scopes of your package, however may this approach be considered legit? In case it is not, do you have any suggestion?

Thank you,
Nicola
