Sigfox_Button example in STSW-S2LP-SFX-DK. Hi I tried to test a custom board (STAM32L073 and S2-LP) using the Sigfox_Button example code. The program gets stuck when I try to send a message. Above I describe the details.

[trx2001]

I changed the pins appropriately in order to adapt the example to the test hardware.

I also stored sigfox ID and PAC in the STM32 flash. The Initializations appear to be successful. Unfortunately when I try to send a message to the Sigfox backend via:

SIGFOX_API_send_frame(customer_data,4,customer_resp,2,0);

the program remains locked on this call forever.

Unfortunately, having no return codes, I am unable to understand the nature of the problem. Is there anyone who has had the same kind of problem and can you help me?

Thanks in advance
