Provide BLE SPP terminal app for Android

[mrx23dot]

Is your feature request related to a problem?

It would be very useful to try out the BLE SPP connection.

Option to set same parameters as
BLESPPCFG:<tx_service_index>,<tx_char_index>,<rx_service_index>,<rx_char_index>
would be great.

Describe the solution you'd like.

An app that can connect/send/receive text to/from ESP32 overs BLE SPP running in esp-at.

Describe alternatives you've considered.

Since it's not standardised as classic SPP there is no other alternative.
connecting a second esp is not less common I think.

Additional context.

also some description would be great how to setup nRF app for BLE SPP, from there anyone can start to build a custom non-hobby app.

You can see the ESP-AT BLE example

I don't see any android app at that site that could be used with SPP,
or mentioning of SimpleBluetoothLeTerminal and how to configure it.
