KC868-A6 LoRaWAN pinout issue

[Alpha]

GPIO13 should not matter, SX1278 uses SPI port. whether can change to use another ESP32 free GPIO pin for a test?

Hello,
Thanks for the response.  I'll try again and see how I go.

I was going to use another ESP32 GPIO but there are many others spare!

Thanks again,

alex

Hello,
Just thought I'd report back my success at getting the A6 to successfully use LoRaWAN and connect to The Things Network.

You have to first solder a jumper wire from SX1278 IO1 to ESP GPIO13, this easy as GPIO13 is exposed on P17 connector (not sure why this wasn't working when I first tried).

I then used the awesome LMIC-node (https://github.com/lnlp/LMIC-node) code.  To get this working I created a new LMIC board definition for the A6 (basically just setting the SPI pin definitions for the SX1278), and then added a new 'env' entry to the platformio.ini file (in that file I set the board type to 'esp32dev').  This worked first try, and even the debug information printed to the OLED!

Can I suggest that if you every create a 'REV 2' of this board (or any others fitted with a LoRa module), that you connect up at least the IO1 pin to the ESP32 to allow LoRaWAN to work without soldering a jumper wire.

Thanks again for such a versatile board!

Cheers,

alex
