General issue report

Hello,

I would like to extend ESP-IDF UART HCI Controller example.
I would like to extend the controller commands with custom vendor specific commands, but I can't find a way to do this.

I will add a custom command on the host side (STM32), but I need to add it also on the ESP32C3 side, so I can make some action when parsing this commands.

Thank you for your help.

please ref to：
https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/hci/controller_hci_uart_esp32c3_and_esp32s3
and change config to support BLE5.0

Thank you. I already enabled that, but I still don't understand how can I make a custom response to a vendor opcode.
When I send vendor specific code, stack automatically responds to it, and I don't know how to change the response.

And I have another question, are there are vendor specific commands that are already implemented?

Thank you for your help.

Making a custom response would require altering Controller code, which we don't recommend.

are there are vendor specific commands that are already implemented?

We do have some of those. May I ask what sort of commands do you need? What specific functions are you looking for?
Thank you.

Hello,

I would like for example to read current firmware version on the module. And I would like to update the firmware through the same UART that it is used for HCI communication.

That is why I wanted to implement a few more commands that I would call as normal HCI commands

Thank you.

Sorry for the late reply. I have checked with my colleagues and unfortunately neither of these options are available at this time.

OK. Thank you.
