Idea for update

[daskalovst]

I have idea for update, ESP32 support...
ESP32 module have build in Bluetooth, with button mode can be change easily form WIFI to Bluetooth.

Normally using smartphone/tablet when you are connected to WIFI, 4G internet is inactive which cause no map update. Most popular GSC APP s available in google play support Bluetooth connection.

I also work on hardware device containing:
ESP32
HM-TRP Radio
Battery
Battery charger
Battery discharge protection
Battery monitor (battery level can be reported via MAV-Link also LED indicator)
Buzzer for low battery
USB for battery charging and software update
Barometric sensor

Early schismatic on the link.
