btle.py doesnt work after reboot

[shailurie]

I've installed bluez 5.30 (downloaded and built manually).
Then clone and build bluepy.
Then I ran python btle.py XX:YY:...... and it worked perfectly.

However after the first restart is doesnt work anymore.

It seems like something in the one of the last changes caused the bluepy to stop working after restart.
the workaround which works for me is commenting out the mgmt_debug function (the one above the main function) and the call to the function (in main function).

I can't reproduce your exact error, but I've spotted a problem in the debugging output which might be the cause. If you could let me know whether commit 693d455 fixes the problem that would be useful.

Thanks

Cannot compile it (error below) due to "Warnings as errors".
However I can tell you this fix will work because by "disabling" DBG, you "disable" mgmt_debug (which now do nothing) and by that, get a similar code to my workaround above (my 2nd comment).

I wouldn't recommend it as it disables all logs.

Bottom line: comment out line 1398 (DBG in mgmt_debug) and the one above it(to prevent :unused variable 'prefix'), and you're good

The "unused variable" warnings should have been fixed in commit 4611544. I found another possible problem with the debugging output, which was fixed in 79adf50.

Let me know if you still have problems.

Thanks,

As mentioned before, you can comment out the content of mgmt_debug and keep
the debugging. I checked it and it works.
Which bluez version should I use with it? (5.29 - 5.35)
