    • RE: AtomDTU NB-IoT not detecting SIM card

      I also noted there is no way to set the APN details using UIFlow.
      I see that using M5Burner one can set the apn using the configuration button on Core, but not on UIFlow_Lite.
      Any advice to add APN setup and still use UIFlow

      @felmue
      RESOLVED: I had the sim card backwards. even though there is a big picture of how to insert it, i still inserted it cut-side first out of habit.
      Thanks for pointing it out.

    • AtomDTU NB-IoT not detecting SIM card

      Hi, I have tried two different ATOMDTU/NB-IoT modules and two different Sim cards but AT commands show Sim not detected. Any advice?
      see details from AT test:

      ati
      SIM7020G R1910
      OK

      at+gmm
      SIM7020G
      OK

      at+gmr
      1910B03SIM7020G
      OK

      at+gsn
      86151xxxxxxxxxx
      OK

      at+cgsn
      86151xxxxxxxxx
      OK

      at+cpin?
      +CME ERROR: SIM not inserted

      See does not detect sim card

      also LED status is:
      red=on
      blue= quick flash once per second

      Thanks
