The stack hangs upon receiving a command on port 203 (Firmware Management Protocol)

[Ramin-Mardani]

SWL2001/smtc_modem_core/lorawan_packages/fuota_packages/lorawan_fmp_package.c

Line 489 in 45e19e5

ctx->fmp_task_ctx_mask |= REQUEST_REBOOT_TASK_MASK;

The device will hang whenever I send a command on port 203 that is specified in Firmware Management Protocol Specification TS006-1.0.0. from the backend. For example, DevVersionReq. 

I will get the following information from the console:

lorawan_fmp_package_service_downlink_handler receive data on port 203
LoRaWAN App got an event
INFO: Event received: TXDONE
INFO: Transmission done
 lorawan_fmp_package launch REQUEST_REBOOT_TASK_MASK n lorawan_fmp_package launch REQUEST_REBOOT_TASK_MASK n lorawan_fmp_package launch REQUEST_REBOOT_TASK_MASK

The stack doesn't respond to the backend and the phrase REQUEST_REBOOT_TASK_MASK n will be endlessly repeated.

Having the same issue,

Changing
ctx->fmp_task_ctx_mask |= REQUEST_REBOOT_TASK_MASK;

to
ctx->fmp_task_ctx_mask |= ANS_CMD_TASK_MASK;

Seems to be the fix,
The same problems occurs in fuota_packages_v2
