GoveeBTTempLogger: Failing on ubuntu 22.04 (linux mint 21) - LE Set Scan Parameters Command Disallowed

Hello,

I am facing trouble trying to make goveebttemplogger work, may be because of latest change in bluetooth stack. The issue happens on first call of hci_le_set_scan_parameters(device_handle, 0x01, htobs(0x0012), htobs(0x0012), 0x01, 0x00, 1000) and it is failing with error : Error: Failed to set scan parameters: Input/output error due to the action being disallowed (see btmon trace below).

On the other side I am able to complete a manual le scan with bluetoothctl on the very same host and see my Govee devices.

So to me it looks very much like this issue where bluetoothctl works but not hcitools.

It seems people recommend to do a hci_reset before see 1 & 2. Yet I don’t understand how the code should be change to have a succesfull bluetooth initialisation - I tried my own code, but it fail the same. I am completely new to bluetooth stack, so can help much more.

Regards,

Yves
