HCI command for setting power levels

[dkdog20]

Is there an HCI command for setting transmission power levels on the esp32? I'd like to be able to configure power levels via an HCI command sent through UART, but am having no luck in finding documentation on what I think would be a vendor-specific extension to HCI.

More precisely, I'd like to interact with the esp32 as described in this example (https://github.com/espressif/esp-idf/tr ... ci_ble_adv), but I would like to extend the example to allow me send a command to set the tx power levels.

Thanks!
