Hi Ed,
What I do is call `gatt.select-attribute` on the characteristic called
"Battery Level", but it is not shown in your case. So maybe this is
the bug that you are encountering. What is the exact version of your
BlueZ (commit sha if possible)? Could you also try tip of tree to see
if this is already fixed?
Hi Sonny,
I'm sorry, I should have noted that this is with the tip of tree,
commit bf09e1f048. Thanks for your help with this!
I am trying this from a different computer today and I find that now the
Battery Service and Battery Level characteristic are showing up, even on
the same devices I was reading the other day. Not sure what's going on,
but I am investigating further. At the moment, it seems more likely
that the problem is either with my devices or with my software. I just
wanted to report back to avoid having you all waste your time. When I
figure this out, I'll send another update. Thanks for the help so far.
OK, it's been a while, but the problem was eventually tracked not to
BlueZ but a Qt component I was using. Essentially, changes in BlueZ
were being tracked by changes in Qt, but there was a problem with the Qt
implementation starting with BlueZ version 5.55. No change required in
BlueZ, and already fixed in Qt, but I thought I'd circle back around and
let you all know the resolution.
