BLE problems with latest bluez update #8

shawaj · 2021-09-14T02:20:54Z

With the latest bluez update, the bluetooth will connect briefly and then within a few seconds will disconnect.

It seems to be similar to #3 and https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=254523&start=75 and RPi-Distro/firmware-nonfree#8

Rolling back seems to fix things

Have got some details - devices, version numbers, and logs of any kind? Running btmon to capture a trace across the connect and disconnect would be helpful.

For comparison, I'm running with bluez 5.50-1.2~deb10u2+rpt1 on a 4B, connecting to a Microsoft Designer Mouse (definitely a BLE device) and it's working well.

@pelwell The device is a Samsung Galaxy S21 5G and the connection is between the Helium Hotspot App and the raspi 4b which is running this codebase for the connection

It works perfectly on a CM3+ with a bluetooth USB dongle (csr8510 chipset) but with the pi4 onboard BT it connects and within a second or two disconnects. Same happens with the advertising interval set to 152.5ms

The btmon trace shows that the device is disconnecting due to "Connection Timeout", about which the BT spec says:

The Connection Timeout error code indicates that the link supervision timeout has expired for a given connection.

This fits, because the timeout is set to 5s and there is a 5s gap in the btmon log.

Try increasing the timeout.
Capture the equivalent btmon trace using the CSR dongle.

shawaj · 2021-10-01T05:04:48Z

@pelwell re increasing the timeout - can I just do that by:

ech0 xx > /sys/kernel/debug/bluetooth/hci0/supervision_timeout

It is currently set to 42 (420ms) but even setting it to 1000 (10s) does not seem to make any difference.

Will get btmon trace with csr8510 and revert back later today

What I don't understand is why the Pi4 Bluetooth would take in excess of 5 seconds to discover the services, when on the csr8510 this is done within 1.5seconds?

Even if I ech0 1000 > /sys/kernel/debug/bluetooth/hci0/supervision_timeout it still gives a supervisor_timeout during the connection of 5000ms...presumably because this is negotiated between the two devices?

pelwell · 2023-02-20T09:48:08Z

Closing because I think will have been fixed by the recent firmware updates - see #9.
