Modem could not work after first reboot of modem FOTA

[Siyou]

Hi,

I am facing the same issue of case 244574, we tried to fix it follow your advice but failed. Here is my code:

	bsdlib_init();
	err = bsdlib_get_init_ret();
    LOG_INF("Initialized bsdlib: %d", err);
	switch (err) {
	......
	}

After the first reboot of modem FOTA, the application cannot get return from bsdlib_init() and will be stuck;

The err would always be -1 after every reboot except above case(first reboot after modem FOTA).

Could you help me get it work with one reboot after modem FOTA?

I am not too sure how the solution in the provided ticket will solve your problem, but before I take a deeper look into this, could you try to set CONFIG_BSD_LIBRARY_SYS_INIT=y (bsdlib will be initialized during SYS_INIT), and only call bsdlib_get_init_ret()? Like done here: https://github.com/NordicPlayground/fw-nrfconnect-nrf/blob/master/samples/nrf9160/http_application_update/src/main.c#L181

Best regards,

Hi Simon,

Thanks, it works.

With your solution I can get the correct return code and then add one more sw reboot when it's MODEM_DFU_RESULT_OK to fix this issue.
