The ltc_lc_init_and_connect() blocks all threads

Thanks for the update. The default priority of the main thread is '0' if your kernel is enabled with preemptive support, and -1 if not (link).

After some more debugging, I realize that I might have goofed with the thread priorities. As long as the data collection thread has higher priority than the LTE thread, it looks a bit better.

After some debugging, I am suspecting that this code is the culprit:

int32_t bsd_os_timedwait(uint32_t context, uint32_t timeout)
{
        /* TODO: to be implemented */
        return 0;
}

It seems to busy wait on the socket while waiting for the AT commands.
