Hi,
Following on from my problems with GATT discovery, I now have another
issue: I have a Python program which waits for the Connected=True
PropertiesChanged callback from dbus, then sends a WriteValue to a
GattCharacteristic1 interface.
The issue is that immediately after the Connected=True message comes
back, a WriteValue fails with "DBusException: org.bluez.Error.Failed:
Not connected". However, calling the WriteValue a few seconds later
executes correctly.
I have bluetoothd running with the debug flag and this is the output
(sorry it's long - also in pastebin at http://pastebin.com/bnNRGpMq):

Any help would be gratefully received.

Yep - worked as described. With the latest from bluez master I don't see
any issues. Roll on 5.35!

Apologies for clicking send too soon on the last message. I can see you
and Luiz created patches for this so I'll pull the latest from master
and try. Currently I'm using the 5.34 release. I'll report back once
I've done that.

I had same issue, and I sent patches to fix it around 2 weeks ago.
Which version of bluetoothd are you using ?
Can you retry when running from repository master ?
