Cellular Connection is lost, How to reconnect?

computechnic · April 19, 2021, 9:59am

Hi everyone

I have a ublox sara-410M module and a stm32F2 chip. In my area, there are some locations where we lose the gsm conenction. So i need to reconnect , but that is not working. My question is how is a reconnect correctly done? Do i need to reset the sara module with an AT command? Should the sara module reconnect on its own? Do i need to delete the iface pointer and create a new one? Do i need to call disconnect? Do i need to call shutdown ?

If i have the following:

iface = CellularContext::get_default_instance()
connectCellularNetwork();
// CellularNetwork is now successfully connected
// Now i want do reconnect
iface->disconnect(); 
connectCellularNetwork();
// This Time it isn't connecting anymore

nsapi_error_t connectCellularNetwork()
{
    nsapi_error_t retcode = NSAPI_ERROR_OK;
    uint8_t retry_counter = 0;

    print_function("Connection cellular network...\n");
    while (iface->get_connection_status() != NSAPI_STATUS_GLOBAL_UP) {
        retcode = iface->connect();
        if (retcode == NSAPI_ERROR_AUTH_FAILURE ) {
            print_function("authentication failure\n");
        } else if (retcode == NSAPI_ERROR_OK ) {
            print_function("done\n");
        } else if (retry_counter > RETRY_COUNT ) {
            print_function("fatal connection failure: %d\n", retcode);
        } else {
			print_function("\nEstablishing cellular connection retry (return code %d)...", retcode);
            retry_counter++;
            continue;
        }
		break;
    }
    return retcode;
}

Below the output:

I see that the problem in the second try is at the very end: “AT+CPGADDR=-1” . But honestly i have no idea why there is a “-1” the second time.

I had issues with connecting immediately after disconnecting too (Quectel modem). As you see in the logs at 13389ms the modem sends a URC (ME DETACH), which is then interpreted by the state machine as a disconnection indication, which messes up the ongoing connection process. This is obviously a bug in the state machine. Waiting for some time (until the URC is received) to reconnect would be a possible workaround. If you can come up with another solution, I would be interested too.

Hi
Ty for your answer. Didn’t noticed the URC(ME DETACH).
However just waiting doesn’t resolve the problem. I have waited 60s until trying to reconnect. But the URC just comes later. See log. (71438ms)

Any other ideas? CellularConnection without the possibility to reconnect is kind of useless

It seems that the modem is sending the URC after the next AT command. So maybe you should ping the modem until you receive the URC, and then try connecting again. I don’t recall having this issue with my modem. In the worst case, you could try turning off and on to start from scratch. The Mbed cellular driver can be annoying with some “edge” cases.
