Hello all,
I am testing a Bluetooth chip on Android . Now, I am in the phase of
testing audio connection functionality but it's failing.I ran hstest
with piantronics Bluetooth headset and the problem seems to happen
after a Parameter Negotiation command to the HS, the HS doesn't reply
with PN RSP but instead with DM and then disconnects what could be .
The same test works fine on ubuntu 11.10 so I am sure the headset is
ok. What could be a possible reason for this behavior ?
Here is hcidump log:
