ISSUE : To switch master/slave role between the devices.
I am trying hard to switch role between bluetooth devices but with no luck.
I know there is "hcitool sr " command which switch role for us but everytime i type this command after establishing connection I got the error shown below...
command -> hcitool sr DC:A9:71:8D:2D:C6 m
Switch role request failed: Input/output error
I have typed 'm' or 's' or full name like master or slave but with no success and also I have typed this command when pairing has been successful and connection has been established.
To verify connection I type following command hcitool con
o/p :
Connections:
ACL DC:A9:71:8D:2D:C6 handle 43 state 1 lm SLAVE AUTH ENCRYPT
what does this mean ? Can soemone please explain me specially "SLAVE" part. What I think of this output is that my in-house device hci0 is connected with mac-address of DC:A9:71:8D:2D:C6 via ACL link and my in-house device is SLAVE. Am I right ?
Also I have noticed that when I perform test again and again then sometimes i started getting result of hcitool con as Master example
ACL DC:A9:71:8D:2D:C6 handle 43 state 1 lm MASTER AUTH ENCRYPT
After struggling for couple of days , I have found the solution.
Requirment #1 ->to switch role and make it permanent till next restart.
**
hciconfig -a hci0 lm master
hciconfig -a hcio lp hold
