I'm trying to develop HFP devices using an embedded board and a bluetooth USB dongle. I'm using Bluez 5.52, Pulseaudio 13.0, Ofono 1.31.
The A2DP profile works well streaming audio from my phone to the audio jack of the embedded device. The HFP has problems. During a call, automatically started using OfonoVcm from a Qt program, I only hear sound from the speaker but no voice arrives to the remote phone.
Prior to starting a call I activate the "headset_audio_gateway" profile by programatically calling: "pactl set-card-profile 2 headset_audio_gateway".
How to setup pulseaudio .pa and .conf files for this?
Below my sinks and sources list prior to call:
pactl list sources short
0 alsa_output.hw_0_0.monitor module-alsa-sink.c s16le 2ch 44100Hz SUSPENDED
1 alsa_input.hw_0_0 module-alsa-source.c s16le 2ch 44100Hz SUSPENDED 2 alsa_output.2.stereo-fallback.monitor module-alsa-card.c s16le 2ch 44100Hz SUSPENDED

Let me know if you need further information related to my actual .pa and .conf Pulseaudio configuration.
Kind regards,
