Dell Wireless 360 bluetooth 2.1 dfu update for linux ?

Question

Is it possible to have the dfu file to upgrade a bluetooth 360 module, without windows ?

(I only have linux on my laptop).

The following update is supposed to include a 2.1+EDR firmware update for this module:

http://support.euro.dell.com/support/downloads/download.aspx?c=fr&l=fr&s=gen&releaseid=R231570&formatcnt=0&libid=0&typeid=-1&dateid=-1&formatid=-1&source=-1&fileid=333170

However after extracting it, digging into the files (.cab, .msi), I was unable to find anything looking like a dfu firmware file.

Where is it ?

Thanks.

Hi there,

Am trying to do the same for my dell latitude d620 bluetooth firmware. I downloaded the driver package from the dell website which looks like this R117967.EXE. Then installed it with wine like this: wine R117967.EXE. Then cd'ed to it like this: cd ~/.wine/drive_c/dell/drivers/R117967/2KXP/DFU/. Finally, I tried to run the firmware update like this: wine DFU.exe. Here I got a popup saying something like "please plug in your computer before continuing". Which is rather ambiguous to say the least. But apparently it means that the hard ware is not being seen by the tool.

The next step am going to try is to use WindowsPE CD and try to run DFU.exe there.

Good luck, and do let me know if you managed to update yours from linux.

Nice writing, Thanks for your effort! This is what I'm looking for.

Honestly I don't believe that wine will have access to the usb stack to do the dfu update,

so trying to run dfu.exe from wine is probably pointless.

Once you get the binary blob, you will just have to run dfutool (as root) to update the firmware.

It is already able to download the firmware and save it to a file:

dfutool archive firmware.bin

=> archives a 724156 bytes file, which looks like a proper csr dfu firmware

I am quite sure it can flash the new firmware, I just need to find it !
