Subject: [bluetooth] btusb duplicate filtering
Date: Sat, 25 Oct 2014 01:22:41 +1100 (EST) [thread overview]
Message-ID: <58517.86.105.94.79.1414160561.squirrel@boosthardware.com> (raw)
Hi,
I am seeing the following behaviour with an android device running the
8723au chipset with bluez + backports + btusb.c (new branch).
Step 1:
1: enable BT via settings UI
2: open BLE scanner app
3: app finds all BLE devices
Step 2:
4: close BLE scanner app
5: open BLE scanner app
6: app cannot find any BLE device
- Szymon has suggested it is related to duplicate filtering and may be
handled at the driver or chipset firmware level.
- I found this post which might provide some useful background info.
http://stackoverflow.com/questions/19502853/android-4-3-ble-filtering-behaviour-of-startlescan
- My question is can I do anything at the driver/kernel/bluez level so
that BLE devices always show up?
LOGS
- I see the following output in logcat:
