<![CDATA[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.

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

0_1662126769031_UIFlowSetAPN_20220902.png

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
Felix
