I am trying to use Bluetooth Chat example to connect to an embedded device. I do not have much information of the device bluetooth architecture. I am able to discover that device but while connecting it gives an error as Unable to connect. I am not able to pair with the device if I try pairing from within the Bluetooth Chat example.
The pairing was successful when I tried pairing from Bluetooth settings. The icon that is shown next to the Bluetooth device name in Bluetooth Settings is of "Headset". So, I guess the device falls in that category. I have tried with different UUID i.e. UUID used in Bluetooth chat example, SPP profile UUID, but still no success.
The error that I get is stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session).
It will be of great help if someone can point me to right direction.
