Serial Communication Between AndroidPhone And Core2

[Ber]

Hi M5,

I'de like to create communication Between my phone running android and my core2 to send receive data
(Eg gps coordinates or sms text,)

I use Automate app from llamalab (tasker like) to run automation on my phone, and it can use tasker plugin...
Bluetooth or ble seems the better way,

I've already send data over classic bluetooth SPP, on several arduino project and i'de like to do it with my M5stack core2

How to create a serial Communication ?
(ble, gatt, spp...)

Best regards ,
