Arduino board support package for LinkIt 7697

arduino-add-on-for-linkit-sdk's Issues

Support Software Serial

There are cases where additional Serial ports are needed:

• Serial (UART0) is used for debugging though USB serial port.
• The pins of UART1 shares the bootstrap pin, which must not be pulled-up during bootstrapping. This causes issues when connecting UART1 to UART devices, which is default to idle HIGH.

Therefore, providing a SoftwareSerial library can be helpful for users when connecting to external UART devices.

Upload fails when the board support package installation path contains space character

When the user name contains space, e.g. C:\Users\User Name\AppData\Local\Arduino15\packages\ , the mt76x7 upload tool fails to upload to LinkIt 7697.

Adding Sleep API

Hi all,
I notice that MT7697 SDK have sleep function
so maybe Arduino API can add a sleep() function to reduce power consumption

here is the function at /core/arduino/delay.c

void sleep(uint32_t ms){
	if(hal_sleep_manager_init() == HAL_SLEEP_MANAGER_ERROR)
    {
        // Check the log for error handling.
        return;
    }
    if(hal_sleep_manager_is_sleep_locked())
    {
        printf("Cannot enter the sleep mode, as the sleep is locked\n");
    }else
    {
        if (hal_sleep_manager_set_sleep_time(ms) == HAL_SLEEP_MANAGER_OK)
        {
            hal_sleep_manager_enter_sleep_mode(HAL_SLEEP_MODE_SLEEP);
        }
    }
}

WiFiUdp::available() returns incorrect result after parsePacket()

Bluetooth LE notification not working

When trying to enable the notification on the Android with my own code, it failed, and the problem is related to the descriptor not found for the characteristic, the APP "nRF Connected" can't enabled the notification too.

AttachInterrupt on USR BTN (GPIO37) triggers immediately

LBLECentral read/write characteristic occasionally fails

In the following code snippet, the read operation succeeds, while the write operation fails - even the UUID attribute is indeed having a WRITABLE permission.

     char a = client.readCharacteristicInt("00010203-0405-0607-0809-0A0B0C0D2B11"); 
     // write  
     int mm = client.writeCharacteristicInt("00010203-0405-0607-0809-0A0B0C0D2B11",6);

Define and Implement extra MCS channel types

Currently there are two channel type:

• MCSControllerChannelOnOff
• MCSDisplayChannelOnOff

Need MCS team to define more channel types to cover common cases for MCS, e.g. Integer/GPS/Game Controller/...etc.

PS2X Library Support

The PS2X library is convenient for support wireless PS2 controllers. Currently it relies on some APIs that are only available to AVR platforms. It would be nice if LinkIt 7697 can support such library.

WiFiClient.connect is slow

Currently it always takes ~3 seconds for WiFiClient.connect() to return. It seems that the delay() logic always results in a 1 second delay.

LBLE hangs after repeatedly scan() and connect()

There are 2 issues:

• disconnect() are not implemented
• the system hangs after scan() and connect() several times

By turning on the debug log in adaptor_layer.c we can see that it's an access violation that caused the system to halt.

Arduino IDE upload failed on macOS

while doing the upload process, the IDE will prompt message: java.io.IOException: Cannot run program "/Users/mtk01643/Library/Arduino15/packages/LinkIt/tools/flash_tool/1.0.0/upload.py": error=13, Permission denied.

It looks like the permission of upload.py is incorrect.

[Feature request] Notification support of LBLECharacteristic

Currently it seems LBLECharacteristic does not support notification
Notification allow central side receive notification of value change.
Ex. 7697 side (as peripheral) simply to update weather informations and Mobile side (as central) to receive notification and process.

BLE Characteristic not handling write request?

Reproduce Steps

Error & Expected Results

After fixing the notification for Android, the Linkit 7697 BLE Characteristic has no response to the write request, the code from the SimplePeripheral sample below switchCharacteristic.isWritten() never returns true...

if (switchCharacteristic.isWritten()) {
const char value = switchCharacteristic.getValue();
switch (value) {
case 1:
digitalWrite(LED_BUILTIN, HIGH);
break;
case 0:
digitalWrite(LED_BUILTIN, LOW);
break;
default:
Serial.println("Unknown value written");
break;
}
}

Could you please add SOFTAP function on Arduino IDE?

Hi All,
I notice that LinkIt 7697 + Arduino IDE without SOFTAP function.

If possible, please add a SOFTAP function on Arduino IDE.

Scenario:

1. LinkIt 7697 turn to AP mode.
2. Smartphone --> setting --> wifi --> connect with LinkIt 7697.
3. Smartphone's APP send socket include my AP SSID and PASSWORD to LinkIt 7697.
4. LinkIt 7697 turn to station mode and setting SSID and PASSWORD connect to internet.

Maybe we need three function like below:

1. Set LinkIt 7697 AP SSID and PASSWORD for client to connect.
2. Stop LinkIt 7697 AP mode.
3. Turn on LinkIt 7697 station mode.

Many thanks. ^ ^

Linkit 7697 in AP mode not accepting connections

Hi, guys,

Just bought a LinkIt 7697 dev board. Trying the AP sample without modifications, I get AP to be boradcasted. However, connecting to it - Android 7 and Windows 10 (with and without static IP), does nothing.

Roadmap / Documentation ?

Hi it looks nice project ^_^

Any plan to add OTA support library / SPIFFS or equivalent library? or any library to bring LinkIt at same level as ESP8266/ESP32 ?

Or is there any detailled documention about SDK / memory mapping to help to port them ?

I have a project currently using ESP8266 and soon ESP32 and I would love to support LinkIt board as well 😸

Thanks

Can support BT-HID Device?

Both ESP32 and nRF8001/nR51822 have libraries that support BT-HID,
Is Linkit-7697 planning to support BT-HID?

Provide Hardware Watch Dog example code

There are HW watch dog functionality in MT7697, but it is not exposed to Arduino.

P2 (GPIO0) becomes HIGH during startup

D2/P2 (GPIO0) becomes OUTPUT HIGH during board startup, before sketch runs. This may cause some issues when attaching D2 to some outpu devices such as switch or LED.

SPI Library Compatibility

When using this library: https://github.com/ZinggJM/GxEPD
The SPI (Software) library does not act normally.

Issues including:

• Does not support multiple beginTransaction() endTransaction() pairs
• Does not allow frequency adjustment
• Does not define #define SPI_HAS_TRANSACTION 1

Allow users to explicitly set MCS controller data channel value

Currently, the MCS controller data channel, such as MCSControllerOnOff does not provide set() to update the data channel value. In some scenarios, such as synchronizing a physical switch with its network counterparts, we need to change the value in MCS from Arduino side.

This feature request is adding a new set() method to all the MCSController classes.

WiFiWebServer uses wrong Analog pin number

the analogChannel pin variable should use [14, 17] range.

`analogWrite()` stops working after `pinMode()` is called

The following example does not work on BSP v0.9.6:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);    // remote this line and this example works.
  
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second


  pinMode(LED_BUILTIN, OUTPUT);
  analogWrite(LED_BUILTIN, 255);   // turn the LED on (HIGH is the voltage level)
  delay(300);                       // wait for a second
  analogWrite(LED_BUILTIN, 0);    // turn the LED off by making the voltage LOW
  delay(300);                       // wait for a second
  analogWrite(LED_BUILTIN, 255);   // turn the LED on (HIGH is the voltage level)
  delay(300);                       // wait for a second
  analogWrite(LED_BUILTIN, 0);    // turn the LED off by making the voltage LOW
  delay(300);                       // wait for a second
}

ssid parameter of WiFi.begin() is not const ?

Should first parameter be const in WiFi.begin API ?

+ int begin(const char* ssid, const char *passphrase);
- int begin(char* ssid, const char *passphrase);
