        Hello @Felix22

        ok, his means your modem is alive and responding.

        Now, please try the following commands (which are the same as are used in Init NB-IoT DTU) block, but we can see the responses of the modem:

        0_1708274932090_UIFlow1_AtomDTU_Test2_20240218.png

        You should get something like:

        b'\r\nOK\r\n'
        b'\r\nOK\r\n'
        b'\r\nOK\r\n'
        b'\r\n+CPIN: READY\r\n\r\nOK\r\n'
        b'\r\n+CGCONTRDP: 1,5,"<YourAPN>","10.100.100.100.255.255.255.0"\r\n\r\nOK\r\n'
        

        Thanks

          Yesterday i have made the similar with Arduino-C-Code and become as Response the carrier Code 28801 = Swisscom-Network but no response in q.beyond-Control-Panel...

          I have tested with a complete new AtomDTU. Flash with v1.13.2

          I think, no response :-((

            Hello @Felix22

            I just read in the q.beyond FAQ says that the SIM card needs to be activated.

            I assume you did that already?

                Hello @Felix22

                ok, let's see what providers your modem can see.

                Note: the last AT command AT+COPS=? can take a couple of minutes as it has to scan through all bands. (in my case it took about 3 minutes.)

                0_1708293101539_UIFlow1_AtomDTU_Test3_20240218.png

                Expected output:

                b'\r\nOK\r\n'
                b'\r\nOK\r\n'
                b'\r\n+COPS: 0,2,"22801",9\r\n\r\nOK\r\n'
                None
                b'\r\n+COPS: (1,"SWISS GSM","SWISS","22801",9),(1,"sunrise","sunrise","22802",9),,(0-4),(0-2)\r\n\r\nOK\r\n'

                    Hello @Felix22

                    ok, so it seem that the modem is registered with Swisscom, but doesn't get an IP address since AT+COPS? succeeds, but AT+CGCONTRDP fails.

                    At this point I am not sure what might be the issue. Is there anything in the q.beyond portal, like a log showing some error?

                    Also since you used your iPhone with that SIM card before there might be some kind of security check not accepting a connection from a different device. On the q.beyond portal, is there a way to reset / clear the data from the previous connection?

                    Thanks

                      Interesting, this is the response from the DigitalRepublic-SIM-Card how has no NarrowBand.
                      He see the Network also...

                        hmm, strange. Do you know which roaming partner (Swisscom and/or Sunrise) q.beyond has in Switzerland for NB-IoT? Maybe worth checking with q.beyond support.

                        Thanks

                          Many thanks.

                          I will write to the support from q.beyond.

                          If the connection will go on. What are the Code for an MQTT connection ?
                          If i become an IP-Address, can i use the "normal" MQTT Blockly ??

                          Regards,
                          Felix

                            Hello @Felix22

                            please refer to the SIM7020 documentation for MQTT commands. You can find the PDFs here - section Related Link.

                            As soon as the modem gets an IP address the last AT command AT+CGCONTRDP sent by Init NB-IoT DTU block should succeed and then you can use all the other MQTT blocks.

                            Thanks

                              a.beyond say, she works in Switzerland with Swisscom NB.
                              How can I explicit connect to Swisscom (AT-Command) ?

                                    it is my understanding that AT+CIFSR returns the local IP address in a TCP or UDP connection. (It's an AT command for compatibility with SIM800.)

                                    See PDF document SIM7020 Series_TCPIP_Application Note_V1.04 - 6.2 TCP Client Connection. You'll find the link to the PDF here.

                                    The way I use to set the APN is described in the same TCP/IP PDF - 3.2 APN Manual Configuration.

                                    Thanks

                                            now, i have a new problem.
                                            The mqtt broker test.mosquitto.test is working with my Blockly but my own Broker on my Server at home in a Docker container is not available from AtomDTU. But with a Internet Test Tool, it is working ( https://testclient-cloud.mqtt.cool/ )
