      @Jeroen-van-Bussel of course you can work on automatic mode, the modem would scan through the whole PLMN list until it finds a network. This can take a while and I agree, it’s the only thing that makes sense for devices in non-static use cases.

      Rise to the challenge and solve global problems concerning Covid-19, Environmental Sensing, or Habitat Destruction using the new SODAQ N3 board. It leverages the advantages of upcoming LTE Cat NB2 networks such as mobility enhancement, E-Cell ID, larger TB size, two HARQ processes, multi-carrier enhancement, single-tone and multi-tone uplink. The SFF board features an integrated Microcontroller (Microchip Atmel SAMD21), GPS (uBlox EVA 8M for GPS (Galileo, GLONASS, and Beidou support) and sensors including LSM303AGR digital magnetometer and accelerometer.

      In collaboration with Sodaq and u-blox we are hosting a competition in which 3 participants can win 10 new SODAQ N3 boards to prove their concept to the world. In addition, the winners will receive 10 Deutsche Telekom SIM cards with one year connectivity. Any developer, for fun or for commercial purposes, can participate in the contest until December 4, 2020. More details: http://sodaq.com/n3-launch-contest/

      @afzal_m Yes, I tried it few minutes before you wrote here :) and it works!

      Thank you very much, we can continue in our small project…

      @Martijn-Kooijman I solved it by checking the return message after sending “AT+USOCR=17,7000”. Once it is contains “+USOCR: 0” in the returning string I know it is ok:
      (it takes about 5 s after a reset)
      added code:

      String check_sara=cmd("AT+USOCR=17,7000"); while ((check_sara.indexOf("+USOCR: 0",1)<0)) { delay(500); check_sara=cmd("AT+USOCR=17,7000"); Serial.println(check_sara);//just for checking }

      @Crowdsourcer I don’t know. BQ24195 is pretty solid. Probe it if you need to.

      You should firstly check your firewall rules. It’s possible that your server accepts incoming UDP packets but drops outgoing packets on that specific port. You should firstly check your firewall rules. If there is a problem on your servers side, I can try to explain to you how you can configure everything in python to get it to work. From this you can adapt it to your tools and infrastructure. First of all we open a socket and tell it to listen to a specific port:

      import socket

      sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
      sock.bind((‘’, 16666)) # bind the socket to address (port)
      message, address = sock.recvfrom(1024)
      Now our server is ready to receive messages on port 16666. From our modem we send some data to the server with IP:Port in our case ww.xx.yy.zz:16666:

      at+nsost=0,ww.xx.yy.zz,16666,3,414243
      In python you will then get something like this

      message = ‘ABC’
      address = (‘85.147.106.108’, 3618)
      With the following command we can send a message back to the client (our NB-IoT module):

      sock.sendto(“Hello World”, address)
      With these commands everything should work properly.

      Make sure that you send the answer from the same socket (i.e. same source port) otherwise it won’t work (network will drop the packets). So for example the following won’t work:

      import socket

      sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
      sock.bind((‘’, 16666)) # bind the socket to address (port)
      message, address = sock.recvfrom(1024)
      …
      Receive some data here
      …
      sock.sendto(‘Hello World!’, address) # this will work fine

      Now we close the socket and open a new one with a different source port (on the same server so same IP)

      sock.close()
      sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
      sock.bind((‘’, 1883)) # different source port than before
      sock.sendto(‘Hello World!’, address)
      Even so we send the packet to the correct address (IP:Port) the module will never receive the packet because the source port ist different this time.

      Please let me know if this was of any help.

      Best regards

      Hi,

      Mijn data komt binnen op mijn eigen applicatie op jullie gateway. Ik probeer deze data door te sturen naar All Things Talk. En in de toekomst ga ik Azure proberen. Heb je misschien ergens een tutorial over die endpoints?

      Thanks.
