Devices not getting Discover

[josephcenk]

Trying to discover the device with 0 or 60 seconds timeout but device is not getting discover. In addition, timeout 0 does not return. Please advise to fix the issue
Please Note : Getting UUID's through bluetoothctl.

What version of Linux are you trying this on? Older kernels don't implement the discovery filter, and you need to build the library with the "-tags nofilter" option to work around that. You can also try to do the discovery filter "by hand" in bluetoothctl, using the set-scan-filter-* commands if you suspect this might be the case. (Timeout = 0 means wait indefinitely, so that bit is working as intended.)

Using Ubuntu 16.04 with Kernel 4.10.0-42-generic. Will try to build library with tags nofilter.

Hmm, that should be plenty new enough (I ran into this issue in the 3.x series), so although it won't hurt, I doubt it will help. I would also try that "discover manually" sequence in bluetoothctl, just to make sure that it *should* work (devices are discoverable, etc.).
