NRF52832 BLE controller (HCI_UART sample) not working
I tried to follow the instructions here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.3.0/zephyr/samples/bluetooth/hci_uart/README.html. The Zephyr version is 2.6.0, with SDK 0.13.0. On my machine Kubuntu 20.04 is running (kernel ver. 5.11.0), with BlueZ v. 5.53
btmon seem to report device detection as in this gist: https://gist.github.com/vinhtran99/9ddaf9bf6d4406cf8d0b401a5879703e
But any command from btmgmt only returns failed with status 0x11 (Invalid Index).
