[Bluez-devel] Error.InProgress forever after DBus timeout on GetRemoteServiceHandles

[Bluez-devel] Error.InProgress forever after DBus timeout on GetRemoteServiceHandles

[Pierre-Yves Paulus]

Hello,

I perform a call on GetRemoteServiceHandles. For some reason it fails 
with a DBus timeout. After it has happened, each subsequent call to 
GetRemoteServiceHandles about this device result in a Error.InProgress.

More precisely, my code tried it 36 times over about 7 minutes, and it 
failed that way each time.

What should I do in such a case? It should somehow effectively timeout, 
or there should be a way to cancel it. I didn't find any in the 
dbus-api.txt file.

Thanks in advance,
Best Regards

from the hcid side it is impossible to know when the request fails due
to a timeout. However calling the FinishRemoteServiceTransaction method
should cleanup the state and make it usable again. If not, then that is
a bug.
