Android Question Bluetooth SPP Helicopter control signals?

[WebbyBoy]

Hi,

I have a BeeWi helicopter that is controlled via Bluetooth under SPP. I would like to use my own application, rather than the downloadable one to control it, but I've no idea about how to find the correct signals to send.

Does anyone out there know how I'd be able to read or find the correct signals to the copter?

I already have a app on my phone which controls it, is there a way to read the signal coming from that?

The copter pairs as a headset is that makes a difference.

If you have another Android phone/tablet with Bluetooth, you can install the Bluetooth example (http://www.b4x.com/android/forum/threads/android-bluetooth-bluetoothadmin-tutorial.14768/), pair it with your first phone and receive the commands from the helicopter app.

Otherwise you can install Termite (http://www.windows7download.com/win7-termite/ekejdiwv.html) or Hercules (http://www.hw-group.com/products/hercules/index_en.html) on your PC, pair it with your phone and receive serial data via Bluetooth (select correct COM port number).

The BT likely interfaces with rx, tx of a UART on the copter controller. It could be hacked by using a logic analyzer. Saleae logic make a fairly inexpensive one. It decodes the characters used on both sides using hardware connection. It will be helpful as a debug tool as you write your code.

Thanks for the replies, I'll give the BT example a go and see if I can communicate.
