How to change APN on Unit Cat-M?



  • AT&T requires a specific APN, and the service does not work without properly setting it. There does not seem to be a UiFlow block for APN, and changing the APN is not mentioned in the docs. Any help with this is appreciated.



  • Hello @HWTaro9

    you can try to send the required AT command yourself. Try something like below:

    Replace YOUR.APN with your APN.

    Note: If you are not using M5Stack Base or Go, then please adjust tx and rx GPIOs accordingly.

    Thanks
