There is various information about a BLE Uart with the ESP32. There is an example in the link from espressif.
Would something like that be possible in in the future for Flowcode 10 (for the ESP32) and for the App Developer?
Various terminal programs for this BLE Uart are already available for Android.
The big advantage of BLE Uart is that it needs much less energy than the BT classic Uart (SPP)
and the connection is built up only lightning fast and for a short time.
The small disadvantage is it can only send a few bytes every few milliseconds.
