Hello,
I have moved slm_shell application t0 a separate thread, including cereg_mon() and slm_shell_data_indication() functions. I can correctly check the SLM (ncs v3.1.1 on nrf9151) responses.
I have modified cereg_mon() to schedule a delayed work, and in that work function I send +cereg=2 command, however, the control is lost:
static void cereg_mon(const char *notif)
{
int status = atoi(notif + strlen("\r\n+CEREG: "));
network_cereg_status = status;
if (status == network_registered_home ||
status == network_registered_roaming) {
if((slm_network_st == slm_network_init_registration) || (slm_network_st == slm_network_not_registered)) {
k_work_schedule(&heartbeat_wrk, K_SECONDS(NETWORK_HEARTBEAT_CHECK_SEC));
LOG_INF("[URC] Verify registration after %d seconds", NETWORK_HEARTBEAT_CHECK_SEC);
}
if (slm_network_st == slm_network_first_time_registered) {
slm_network_st = slm_network_is_registered;
}
k_work_cancel_delayable(&retry_wrk);
retry_counter = 0;
printk("2state:%d\r\n", slm_network_st);
}
else {
LOG_WRN("[URC] LTE detached or denied (status: %d)", status);
slm_network_st = slm_network_not_registered;
k_work_schedule(&retry_wrk, K_SECONDS(NETWORK_RETRY_DELAY));
printk("3state:%d\r\n", slm_network_st);
}
}
in the work function below:
static void heartbeat_worker_fn(struct k_work *work)
{
int rc;
ARG_UNUSED(work);
slm_network_st = slm_network_first_time_registered;
rc = modem_slm_send_cmd("AT+CEREG=3\r\n", AT_CMD_TIMEOUT_MS);
LOG_INF("heartbeat!");
return;
}
after sending +cereg=3 the control is lost and it doesn't enter cereg_mon().
Can you please advise how to resolve it?
