BC127: Bluetooth Link Key


#1

Hi, I am using BC127 as a development board. I use BC127 to connect with my headset an an SPP connection and send byte stream data in command mode. I want to capture the sniffer log of the same using sniffer tool. For that I need to input bluetooth link key of the connection in sniffer tool. So is there way to get the link key?

Reagrds,

@manish,

Assuming you are referring to Simple Pairing Protocol (as opposed to Serial Port Profile) then no, there is no way to get the link key out of the unit.

@mlw,
No I am reffering serial port profile.

@manish,

In which case turn Simple Pairing Protocol off then you can define the key yourself, this protocol just simplifies the pairing process (and makes it more secure because the key will be random and larger than a person would choose).
