Robert,

The write call returned EAGAIN, so we should resend the data after a while.

It should succeed if you wait long enough. Set the delay to 2000 and do more tries (like 1000). Unfortunately, waiting too much will lead to gaps in the sound when this happen.

I think the cause is elsewhere, could you send us the hcidump -V log?
Do you have another program using BlueZ? Another headset to try?
You could try a shorter bitpool (say 32) if your headset supports it to save some bandwith.
