praveenpalaparthi

Hi Team,

I have flashed the given serial LTE Modem hex file(attached) into dev kit nRF9160 and tested TCP server mode.

I am facing issue with AT command: AT#XBIND=3442\r\n, due to this I am unable to open TCP server socket.

Log attached for your reference.serial_lte_modem_22_04.hex

    Hi Martin,

    I have flashed debug_serial_lte_modem_27_04.hex file and tried  TCP server mode, its failing at same AT command, AT#XBIND=5003.

    I am attached log generated from serial tool for your reference.

    Hi Praveen,

    Since we are able to get it working on the live network at our side, we will get a hold on a CMW500 to try to reproduce the issue you are seeing.

    note:

    The reason xbind command worked in NCSv1.2 is that it binds to any address (local.sind_addr.s_addr = htonl(INADDR_ANY);)

    Later introduced in master branch is the support of TCP/IP server, where the Serial LTE modem sample (the sample attached in this thread) uses modem info to fetch the allocated IPv4 address and bind to it. So in your test case, the nRF91 might not get a valid IPv4 address.

    (hence output log: 

    [00:12:56.948,455] <err> tcpip: Invalid local address
    ),

    This can be verified with the standard AT command: AT+CGDCONT?
