[Bluez-devel] Bluetooth / WiFi USB concurrency issue

[Bluez-devel] Bluetooth / WiFi USB concurrency issue

[Olivier Le Pogam]

Hello,

I have a bluetooth device on a USB slot and a WiFi device on another USB 
slot, and my mini-ATX PC (Ubuntu 7.04 kernel 2.6.30
Bluez 3.9) is connected to the network thanks to the WiFi/DHCP.

I have noticed that when a scan (sdptool) is performed, the network link (if 
I perform a simple "wget" for example) is either slowed down or interrupted 
(not sure) and carried one / completed once the scan is finished. On a 
former kernel / bluez it was simply crashed and I had to up/down the 
bluetooth device.

Do you have any idea why this weird thing happens ?

Thanks a lot,
Oli

Hello Olivier,

What you experience is bluetooth/wifi coexistence issues.
Your wifi chip must have bt coexistence support in order to work when 
their is some bt activity.

Cheers,

Fabien

Hello Fabien,

Thanks a lot for this !!

I actually use this driver : RT73(RT2571W) Wireless Lan Linux Driver
which is built as rt73.ko kernel module.
I'm currently trying to find how/if the bt_coexist support is managed for 
this device !

Cheers,
Oli
