--- Comment #4 from Francesco Bonanno <[email protected]> --- Hello, after some time I have started to work again with the my asus t200ta. I have the bluetooth module working now!

https://github.com/LGSInnovations/edison-yocto-image/raw/master/edison-image-edison-ext4/etc/firmware/bcm43341.hcd
this is the firmware used to get it working (I've originally unpacked it from the intel edison image, anyway I have found this repository where it is pushed already, so you can take the firmware here for tests)

After I have discovered that the bcm43341 (at least on my t200ta and with linux 4.7rc3) is seen as a bcm43341B0 on /dev/ttyS4

[ 1251.074780] Bluetooth: hci1: BCM: chip id 82
[ 1251.074792] Bluetooth: hci1: BCM43341B0 (002.001.014) build 0000

So I have put the firmware under /lib/firmware/brcm/BCM43341B0.hcd where btattach is looking for it and after I have launched it with:

"btattach --bredr /dev/ttyS4 -P bcm" as root, and it is working without issues!

I have put the command under /etc/rc.local as workaround, however I imagine that you will find a better solution to have it recognised automatically by the kernel.

I hope all this will be usefull!
