    • RE: Data packet size [Roaming]

      As roaming is more or less transparent for the device as well as backend-end server, this recommendation formulated here https://forum.iotcreators.com/topic/594/data-packet-size still applies.

    • RE: LTE-M not registering in NL

      @rxtx

      AT+COPS=1,2,"20416"
      2022-02-17T10:57:35.077Z DEBUG modem << OK
      2022-02-17T10:57:38.329Z DEBUG modem >> AT+CFUN=1
      2022-02-17T10:57:38.378Z DEBUG modem << OK
      

      You turn on the radio after you perform the manual attach. This looks strange for me. Not sure whether the manual attach works in this case. Please turn on the radio (at+cfun=1) before you perform the manual attach. usually you can can choose the RAT type while doing the manual attach. That would be:

      AT+COPS=1,2,"20416",7
      

      7 for LTE-M on your module. Try this pls. not sure whether that works on your module.

    • RE: IPv6 can't receive any packet via m2m.public.nl

      I can confirm the issue. I can reproduce it. The problem occurs not due to LTE-M but due to this specific APN (m2m.public.nl). @Uta will take care of this

      I will look into that. In the meantime:
      Have you already tested IPv4 ?

    • RE: tmux and netcat listener Linux question

      @aliza-izaton As mentioned earlier, I strongly recommend using a python-based solution.

    • RE: TCP listener seems to be killed or stalled

      You think that he button does not close the TCP socket correctly (meaning without sending FIN)?
