lescan stops after 10-15 minutes (bluez 5.48)

lescan stops after 10-15 minutes (bluez 5.48)

[Gabriel A. Zorrilla]

Hello there. I'm really desperate here. I'm trying to work with BLE in
my Pi3. When i do:

sudo hcitools lescan (with or without -duplicates) the Pi scans
normally then stops after about 10-15 minutes.

Here I made some btmon dumps:
without duplicates: http://termbin.com/ox3z
with duplicates: http://termbin.com/6nnn

* Pi3
* Raspbian with 4.9.66-v7+ kernel.
* Embedded bluetooth.
* Compilled bluez 5.48

Don't know what extra info you would need to diagnose this. Perhaps
it's a common bug in the Pi3 Raspbian distro, but cant find
information about this on the web. Been googling for a week.

I really want to make this work, so dont hesitate in asking me some
tests and such.

Thanks and regards,

Hi Barry,

Dont think so. The size of the dumps are over 4k sometimes and
sometimes less and the btmon output does not mention any buffer size
issue.

But i'm no expert.

Thanks!

You don't want to mix using HCI directly and bluetoothd. Bluetoothd will 
interfere with you accessing controller and this is most likely what you are 
seeing.

Is there a reason for you to use hcitool lescan instead of D-Bus APIs?

Hi Symon,

This started because some Node-Red detect BLE devices but after a few
minutes they stop getting input. Then started to diagnose BLE with
hcitools and the outcome was the same so started to believe a kernel
or controller issue.

If there is an example of how this API works i'll be charmed to test it.

Thanks!

Found a python library: https://github.com/frawau/aioblescan, same
thing, stops after 10 minutes.

You can check test-discovery under test/ folder in bluez tree.
