Is there a known working miniPCIe card for the TK1 which supports Wifi ac and BTLE5.0? We are not using the mainline kernel. Regards
Actually you can use any Intel based wifi dongle which has proper Linux Drivers. You will need to backport the drivers.
The intel AC9260 looks promising. IMHO the driver is included starting with kernel 4.14. So would it work with the mainline kernel?
This should work out of box.
How about the backports? Are there any backports for the downstream kernel 3.10 including BT?
The Wifi part is ported to the downstream kernel, so it should work out of box. However it may be that not all the features of your wifi dongle will work. Bluetooth was not ported back to the downstream kernel. You will need to try this on the downstream kernel and backport this from mainline kernel. We won’t port back BT to the downstream kernel.
