Configured from the 2.0 IDF release. Nothing but BT, in passthrough controller mode. Original pin selection doesn't seem to work from the example code. Set new pin selection. Doesn't seem to work either. Annoying.
Any more help/documentation than just cowpile it and set the menuconfig options to no BT library support and UART controller? Debug settings that I can turn on to see if it's even getting to the VHCI layer pieces right to drive the controller core?
