btmgmt: failure with advertising report event

btmgmt: failure with advertising report event

[Ankur Patel]

Hello Friends,

I am using Linux Kernel 3.10.32 on i.mx28 based platform with TI WL1831 WiFi/BT Module. It runs linux with Bluez 5.30. I am trying to run tests on PTS esp. for LE only mode. Hence following http://git.kernel.org/cgit/bluetooth/bluez.git/tree/android/pts-gap.txt commands to execute on device with "btmgmt" to run the tests. It fails to execute most of the commands mentioned for 
eg. "btmgmt advertising on"

It returns with Error:
root@imx28evk:~# btmgmt advertising on
Set Advertising for hci0 failed with status 0x01 (Unknown Command)

Any pointers on how to solve this error?

I have read some more documentation and found (not sure) that full feature for btmgmt is supported with Linux Kernel 3.18 only. Is that true? If Yes, Is there any way I can use that with v3.10.32?

Regards,
Ankur

You need newer kernel. Or at least newer kernel bluetooth subsystem ie via 
backports project [1].

You can check in mgmt-api.txt [2] what commands were introduced in which 
kernel version.
