Need to determine whether the central and peripheral devices (both running Bluetooth 5.0) are communicating via the faster LE 2M PHY bit rate.
The command I am sending via the hcitool:
sudo hcitool cmd 8 30 40 0
The response received:
01 30 20 01
The btmon output:

For some reason I am getting the Unknown HCI Command error when running this command on the RPi 4 which is set as the peripheral via bleno.
Am I doing something wrong? Are there preliminary steps I need to take before I can read and set the symbol rate?
