      Hi guys,

      I'm having trouble with converting a code I put together for measuring temp and sending it to Blynk. the issue is it works fine using the wifi built into the M5Station but once I try converting it to NB-IoT (U111) I find its not that easy, I have been trying to find a little bit of code I can review that use's the M5Station with the NB-IoT U111 module to say send a test test signal and maybe if connected print a "connected " in the serial printer or even something on the screen of the m5station. Any help would be greatly apricated. Cheers in advance and I hope this isn't a question every man and his dog is asking as I've had a quick look at the forum and can't see anything.

        Hello @GAZZZ6

        I don't see NB-IoT (SIM7020) as supported on the Blynk website. See here - Arduino connection types - Cellular (GSM/3G/LTE).

        Also the Blynk code templates use TinyGSM which also doesn't support SIM7020 (yet).

        Maybe consider a modem that already is supported by Blynk?

        Thanks

          Cheers for the reply Felix, had a small feeling that might have been the case but wondered why the NB-IoT module shows up in the Uiflow program and not be supported, would you know if there is another IoT within the Uiflow program that will support a SIM7020, as I've had this unit brought from M5 for awhile thinking it would be a great why of connecting my M5Station to the outside world :)

          Cheers

            I didn't realize you are looking for an UIFlow solution.

            UIFlow has a configuration flag which allows to connect via modem instead of WiFi. However that option only seems to be implemented for M5Stack devices with can stack COM.X modules.

            I've tried to enable that option for M5Station, but it is ignored and the connection goes through WiFi still.

            Thanks
