      Hi,

      I have a dragino NB-IOt bee with the Quectel BG96 on an arduino and try to connect using a tmobile NB-IOT sim form the starter kit.
      I can send AT commands to the unit and get proper response.
      following this cookbook i do get an IP address but cannot ping anything. Can anyoune see what goes wrong here?
      Thanks.
      Here is my AT communication after a reset:

        Because you are using the wrong command for ping. Try AT+QPING:

        0_1585832821190_2124aa1d-5ed4-40a3-b83d-4b7fbf68fa56-image.png

        See https://www.quectel.com/UploadImage/Downlad/Quectel_BG96_TCP(IP)_AT_Commands_Manual_V1.0.pdf
        and https://www.quectel.com/UploadImage/Downlad/Quectel_BG96_AT_Commands_Manual_V2.1.pdf

          thanks very much Stefan.
          AT+QPING=1,“8.8.8.8”

          OK

            +QPING: 569 means an operation timeout, you can try to increase the timeout period (default is 4 sec).
            f.e. AT+QPING=1,“8.8.8.8”,15,4 (timeout = 15 sec)

            Best Regards, Wesley

              @wesley-top Thanks for your input Wesley. I tried it , sadly the ping still times out:
              AT+QPING=1,“8.8.8.8”,15,4

              OK

              +QPING: 569

                @kkoen when I try to ping the IP address suggested on the t-mobiel site I do get a response:

                AT+QPING=1,“172.27.131.100”,15,4

                OK

                +QPING: 0,“172.27.131.100”,32,752,255

                +QPING: 0,“172.27.131.100”,32,185,255

                  Yes, we hide your devices from the public internet @Kkoen 🙂

                  So pinging directly to 8.8.8.8 will not work

                    Excuse me being ignorant, I’m new to this.

                    Step IV from the getting started guide: hello world.
                    I registered my device by entering the IMEI in the webpage.
                    Next: Open a local socket.
                    The suggested command gives an error.

                    AT+NSOCR=“DGRAM”,17,7000,1

                    ERROR

                    in the BG96 manual I find AT+QIOPEN command. Should I use that instead?

                      Yeah maybe the command for the qualcomm chipset is different
                      So trying this other command could work

                      I will also try to find out for you in the meantime

                          It works!
                          AT+QIOPEN=1,0,“UDP SERVICE”,“127.0.0.1”,0,5683,0

                          OK
                          AT+QISEND=0,11,“172.27.131.100”,15683

                          Hello world
                          SEND OK

                          gives 48656c6c6f205975726921 in the project page which translates to Hello world.

                          Looks like wer’e in business! Thanks for the quick responses.
