Description of problem: Waiting for an "on indication" event can lead to a dealock Version-Release number of selected component (if applicable): python3-gattlib-0.20201113-1.fc33.x86_64 How reproducible: Always (but might depend on hardware) Steps to Reproduce: Minimal, complete, viable example (might be dependent on hardware): import time from gattlib import GATTRequester req = GATTRequester("00:11:22:33:44:55") req.write_by_handle(0x001f, bytes([0x02, 0x00])) time.sleep(1) req.write_by_handle(0x001e, bytes([0xc0, 0x55, 0x02, 0x01, 0x00, 0x1a])) time.sleep(1) req.write_by_handle(0x001e, bytes([0xc0, 0x56, 0x01, 0x00, 0x1e])) time.sleep(1) req.write_by_handle(0x001e, bytes([0xc0, 0x56, 0x01, 0x00, 0x1e])) time.sleep(1) Actual results: on indication, handle: 0x1e -> 00:00:10:02:08:ffffffec:05:00:00:00:00:00:00:00:00:00:00:00:00:ffffffa4: Expected results: on indication, handle: 0x1e -> 00:00:10:02:08:ffffffeb:05:00:00:00:00:00:00:00:00:00:00:00:00:06: on indication, handle: 0x1e -> 00:00:00:ffffff82: on indication, handle: 0x1e -> 00:ffffffc0:55:10:02:09:ffffffeb:05:00:00:00:00:00:00:00:00:00:00:00:00:2c: on indication, handle: 0x1e -> 00:00:00:ffffff82: on indication, handle: 0x1e -> 00:ffffffc0:55:10:06:08:ffffffec:05:47:72:41:3f:00:00:00:00:00:00:00:00:1c: Additional info: Fix is already upstream: https://github.com/oscaracena/pygattlib/commit/018d852f860c415bf68897820570432ba9b0ba04 Please include this in the package or ask upstream about a bugfix release.
