Question half-related to B4A (Bluetooth-VB6)

B4A sends and received raw bytes. Which protocol does your VB6 program expect?

Erel,
thanks so much for the response..
I used to use MSComm1 to receive byte arrays from microcontroller or another
PC through serial port connected to RF radio 9.6k,8,1,none... the microcontroller
had built-in Max232 or Max485 chip that handled all communication business, so
in fact I didn't need to bother knowing how things went on..
Can I use the same RF radio and receive incoming data from bluetooth the same
way I was receiving them from remote radios?

Communicating with Bluetooth is not complicated. You should go over these tutorials:
AsyncStreams Tutorial
Android Bluetooth / BluetoothAdmin Tutorial

How are you connecting the bluetooth module to the PC?

Are you at least getting a successful pairing with the Android?

Why/how would you want to use your existing RF radio if you are using bluetooth?

A bit more information would help..

Thanks Erel,
will do according to your advice.

didn't try anything because I don't know where to start.

I want to extend communication range beyond 200m, so I will use data radio
