Anyone find a good alternative to the 1500?

Official Hardware MKR Family MKR NB 1500

I'm a experienced mkr modem fighter ;=), went also trough the loony bin...

But IMHO Arduino is right, it's a u blox product. Also firmware updates are common (think of personal computers). This is open source hard and software, it's not enduser stuff. Keep the faith! I was also often close to abandon but nobody can help you exept github, this forum and RTFM.
My hints:

  • You need 5.12, a lot of issues were solved with that firmware:
    Firmware upgrade for UBLOX SARA-R410M-02B on the MKR NB 1500 #2 - #33 by rhttu
  • Bad news: No solution for just terminal or xmodem, you have to solder a USB plug to the board...
  • In general: The modem is it's own computer and you can only communicate via the AT interface. So timing is important. Check with access(true) if the AT commands come with proper timing for answer from the modem etc.
  • The new core lib has a undiscoverd bug deep down (something with the MODEM buffer) so 1.8.9 is more reliable then 1.8.11.
  • In doubt, try out your commands with the serial passtrough sketch.

Back to your question :crazy_face: I will try out the telit charlie board:
