I'm trying to understand the features currently supported by oFono
regarding the handsfree role in Bluetooth/HFP. My first impression
looking at the source code is that some HFP functionality might be
missing, but I would rather have your confirmation.
Some examples I've found so far are the following:
1. Response and hold (AT+BTRH=0)
2. Redial last number (AT+BLDN)
3. Retrieval of supported Bluetooth features for a certain modem/device
Could you clarify which (if any) of these features are currently
supported by oFono?
In general, is there any documented list of unsupported features?
