How to change APN on Unit Cat-M?

[HWTaro9]

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
