Newbie getting started commucating with Android smart phone to RN-52 module

[rwl4bt]

I have two RN-52 blue tooth module communicating with each other with UART. Now I want to communicate with my Android OS smart phone. Need an AP, e.g. send a ASCII from phone to RN-52.
Where do I start. (My first post)

You need to use the Serial library together with AsyncStreams (RandomAccessFile library).

Check this example: https://www.b4x.com/android/forum/threads/14768/#content
Make sure to initialize AsyncStreams in non-prefix mode.
