during the pairing process you have to pair & accept three times for three devices.
Each pair of Phonak HA come with three Bluetooth device handlers.
There are two Bluetooth Low Energy devices ( Left / Right hearing aid controlls are the low energy ones , the BT_LE R and BT_LE L ) and this two are only handling the controlling features via the MyPhonak App (no audio signal processing happens on these two bluetooth devices)
The third Bluetooth Device have a symbol looking like a Headset and this is the one you need for the audio streaming & Phone Calls/hands free feature. This is the classic bluetooth device for audio signals: R-Phonak hearing aid
So during the pairing process you should get three devices that you need to accept and confirm.
If you only have paired the one R-Phonak hearing aid paired, then you are ready to have the audio stream for both hearing aids. Because there is only one hearing aid (the right R) that act as master hearing aid and the right aid sends the audio to the left hearing aid ( intercom from device R to device L)
