When i try to connect with a device, it says that the device is not connected. I know that bluetooth is turned on, and i have both devices paired with each other. I cant figure out what could be wrong with it. I'm still trying to figure how the bluetooth functionality works in appinventer, so any help is appreciated. Thanks!
There are many Bluetooth examples in this Community, please do simple examples and then adapt them.
Sorry i wasn't specifc enough, im trying to send data between two mobile phones. Im not doing anything with an Arduino. I'm gonna try using bluetoothLE, really should've looked at the documentation more closely. i'll post again if i need help with it.
