TTN_OTAA example fails at T-MOTION device

[efreeform]

I am trying TTN_OTTA example at the T-MOTION board. I managed to successfully upload it to the device but after putting it back at the USB port at the serial terminal i receive the following:

LoRa Receiver FAILURE

[efreeform]

it seems that the PINOUT for T-MOTION at the example is wrong

[efreeform]

The PInout is OK, i added the following line const lmic_pinmap *pPinMap=&lmic_pins;

and replace os_init(); with os_init_ex(pPinMap).

Now it passes the os_init state but it fails at the LMIC_reset() with an error radio.c:1164

@efreeform I tested the LoRaWAN/OTTA example and it works fine.

You can update this repo.

I am using platformio, and made some modifications to platformio.ini:
