Bluetooth Certification Testing L2CAP eRTM Test Failing

Bluetooth Certification Testing L2CAP eRTM Test Failing

[Heiko Abraham]

Hi,

I am trying to qualify our Bluez 5.45 stack as a host subsystem with the
Bluetooth Sig. Right now I am running into an issue with eRTM. It looks
like eRTM is not well supported.

I use kernel 3.12.74 and BlueZ 5.45 on an ARM platform.

Can anyone tell me, if eRTM works well with kernel 3.12.x?


Best Regards
Heiko Abraham

I don't have a specific answer to this question, but I do find myself
in a similar situation of trying to figure out which functions of
BlueZ 5 might or might not work when used with an older kernel,
3.12.70 in my case. I haven't found a specific source of information
on this topic, only scattered references to the fact that some BlueZ 5
features only work with newer (4.1+?) kernels. Is there a
comprehensive source for this info?

if it is supported in 3.12 is something I do not recall since that kernel is so old. It should be supported there since the feature is pretty old.

Above are the links for doing PTS qualification of L2CAP.
