[SOLVED] Bluetooth keeps searching for devices on LM 20

Post by naveenbp »

Hello All,
I noted that the bluetooth keeps searching for devices and does not connect to any, in fact i do not get to see the list of devices nearby which have their bluetooth ON.

I have not tried any solution yet as i could not figure out what the output of commands (in my system) actually mean, I am attaching the code here, kindly guide:
