The FAQ on the Wiki appears to indicate that you need to build the source is a kernel version > 2.6. However, the build fails on Jessie running kernel version 3.16.51-3 because of no ell. Not big deal. I was able to download it and build it but the ell web page suggests I need the latest kernel version - 4.17 for things to work. I haven't actually installed ell to see if that was only requirement for the build which wasn't mentioned in the README. So am I wasting my time the release from https://git.kernel.org/pub/scm/bluetooth/bluez.git ? I don't mind installing additional packages from source provided it fixes the known problems with bluetooth. I am currently using 5.49 from https://github.com/Vudentz/BlueZ.git It doesn't require ell to build. The following URL https://www.theregister.co.uk/2018/07/24/bluetooth_cryptography_bug/ which is what got me started looking for information and possible fixes. Any help would be greatly appreciated. -- Cinaed -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
