NB-IoT Region Support and APN Setup
Americo last edited by
Hi all, I'm using the NB-IoT Module based on the M5311 modem, I followed all the requirements to connect the uart port of the modem to a suitable pin on my M5Stack Fire Core, the AT commands works just fine but I'm unable to get the module registred on the cellular network, the sim card is active and works perfectly in other devices. I noticed that the default arduino code do not set the apn to setup the data connection, how can I do that ? Is there a way to diagnose the problem I have ? Thanks a lot to everyone will join !
