All,
I'm porting our company's application from bluez4 to bluez5. I'm currently=
using bluez5.42 (I'm nervous about using higher than that because I've ha=
d to backport many kernel changes to support this recent version (what else=
do I need to backport?)). I have most things working, but there are two i=
ssues I've not yet been able to resolve. The first is devices reconnecting=
when they come back into range. For example, I am testing with a Jawbone =
from Jambox. When coming back into range (or powering back on), I watch it=
attempt to connect, and it fails. If I have bluetoothctl up I see the sta=
tus change from connected to unconnected about three or four times before t=
he Jambox quits trying and powers back down. I have a BTLE keyboard that =
comes back into range and will not connect until I hit a key and the connec=
tion happens. I have other BTLE devices that attempt to reconnect, but fa=
il as well.
The second issue is that of headset devices. In Bluez4 there was a headse=
t 'profile' and the IndicateCall method that could be invoked. In bluez5 t=
here is the Alert1 interface with the NewAlert call, but it is deprecated c=
ode, so what should I be using? As a matter of interest, if I try to use t=
he NewAlert method what is the proper use? I've tried:
root# dbus-send --print-reply --system --dest=3Dorg.bluez --type=3Dmethod_c=
all /org/bluez org.bluez.Alert1.NewAlert string:"ringer" uint16:1 string:"a=
ctive"
Error org.bluez.Error.InvalidArguments: Invalid arguments in method call
TIA,
Tom

If you would like to stay around 5.42 I would suggest going for 5.43
instead as this is a mostly bug fix release over 5.42.
As for the re-connection issues the best would be to capture HCI traces
using btmon and analyze them to know why the connection attempt is denied.
Best,
