There is no serial response from this unit. No answer to AT @ 115200. Any idea?

Hello @ckuehnel

could you share some additional information? E.g.
- which M5Stack core is it connected to?
- which Groove port are you using?
- how do you initialize the serial connection?
- which GPIOs are you using for TX and RX?
- could you share your UiFlow or Arduino code?
Also these SIM7xxx modems take some time to initialize before they react to AT commands. Try sending the AT command a couple of times.

Thanks
