Hello! I don't know if this is the correct forum to ask it. I'm new with the android development and I am doing an application using the bluetooth but I have some problems. I have a device that make a buzz when receive a command like CMD=1 via bluetooth and I want to send commands to that device to control the buzz. Now I'm using the BluetoothChat sample that has the API to do that, I connect my Nexus One (Android version 2.2.1) with the device, but when I type the command CMD=1 the device doesn't make a buzz. What can I do to know where is the problem and if the device receive the command?
