[PATCH] bluetooth: Fix bluetooth.nrec property not updated

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



PropertyChanged signal of org.BlueZ.MediaTransport is processed in
pa_bluetooth_transport_parse_property() which updates t->nrec.
This is called by :
- First by filter_cb() of bluetooth-util.c
- Then by filter_cb()of module-bluetooth-device.c which retrieve value
  of t->nrec before calling parse function, then it checks if t->nrec
  has changed before updating bluetooth.nrec property.
  As t->nrec has alreday been changed during first process, property
  update is never performed.
