LAUNCHXL-CC1310: [BUG] Downlink message in TI-SIGFOX project

Part Number: LAUNCHXL-CC1310
Other Parts Discussed in Thread: CC1310

Hello,

In the TI-SIGFOX project, I found that always after I send downlink message and It’s well done. I receive the message in the Sigfox backend. But, after that, the program crush and I can do nothing. Even I can’t read the ID of the device. I debugged the code and I discovered that the program exit with an error after invoking the function that send the downlink message (framed in red) and I never reach the Breakpoint highlighted in yellow. I can’t see the value of the function return because the program exit and I can’t debug after that.

The problem is the same even with this function in sigfox_api.h :

sfx_error_t SIGFOX_API_send_frame(sfx_u8 *customer_data, sfx_u8 customer_data_length,  sfx_u8 *customer_response,  sfx_u8 tx_repeat,  sfx_bool initiate_downlink_flag);

The problem is only with downlink messages. With uplink messages, it works well.

Please, could you help me? I need to have solution for that.

Thank you !

Best regards,
