I am developing an application where I have to connect to Bluetooth device on Android 4.3.

And I want to bilateral communicate between Android APP and CC2541 Keyfob.

My ideas is:

1. I connect to the CC2541 keyfob and send the Text data from my APP to CC2541 Keyfob.

2. And the CC2541 keyfob will show the text on the PC via UART after it receive the text from Android APP.

3. After CC2541 keyfob receive the text , it will send the text back to the Android APP.

The question like the following:

1. Which profile and service should I use to send the text data??

2. How to send the text data to CC2541 keyfob in Android application 4.3 ??

3. How to receive the text data on CC2541 side ??

If your app is the only user of the keyfob you could decide on your own protocol. Also see this post and answers: How to send the text data to CC2541 keyfob via Android 4.3? And this one: Android: Bluetooth Low Energy GATT Profile
