Hands-Free Profile installing is difficult

Post by yankon12 » Mon Mar 11, 2019 3:19 am

Hello,

I'm trying to route phone calls from the phone to Android Auto. When I place a phone call, the call does not come out from the Andriod Auto nor Open Auto Pro. The call stays within the phone like if it was a normal call. I looked on the forum and found a guide on how to install Hand Free Profile, but it isnt working. I do have an external Bluetooth Dongle connected to the Raspberry pi.


Link to the guide

In the OpenAuto Pro there is no need to install anything in order to use HFP profile. You have to connect via BT to the RPI, grant all necessary permissions from your phone and that is all.

Please have a look at this movie:

I did the same steps as the video even before watching the video, and still nothing. I've tried with two Android phones and still the calls stay within the phone. I checked the Open Auto Pro Bluetooth settings and the "Local" option was selected. I also checked the permissions on my phone for the bluetooth of Open Auto Pro and the call audio option was selected. I've tried everything. Is there an config file I can share with you guys?

Thanks

Hello,
You do not need adjustment of any configuration in order to use Bluetooth in OpenAuto Pro. Please provide us below details:

1. What Bluetooth adapter do you use?
2. Do you see Bluetooth icon on the TopBar that indicates Bluetooth connection with the phone?

Try to execute sudo btswitch external if you use external Bluetooth adapter or sudo btswitch internal if you use built-in Raspberry PI Bluetooth adapter.

From time to time we receive a feedback that some phones have compatibility issues with internal Bluetooth adapter or external dongles based on the Broadcom chip. If this is possible and not done yet, please try to test Bluetooth connectivity with external Bluetooth dongle without Broadcom chip onboard.

Regarding Adapter type option - it should be set to Local if you use Bluetooth adapter connected to the Raspberry PI (either internal or external).

Hello,

I tried the "sudo btswitch external" command and that still did not work. I can see the bluetooth icon in Open Auto Pro indicating that my phone is connected. I also see the bluetooth icon on Raspbian. The setting on OAP is set to Local as well. I disabled the bulit-in bluetooth so it wouldn't interfere with the dongle. The phone IS connecting to the Raspberry Pi but that one function that I want it to do which is, making the audio of calls come out of the Open Auto Pro and not from the phone, is not functioning :| :?: . I have a Samsung S7 Edge and it connects to a separate bluetooth adapter I have on my home stereo just fine.

I feel like starting over with a fresh install of Open Auto Pro and go from there. This should be very simple and its getting complicated for no reason.

Bluetooth Dongle I have
https://www.amazon.com/TECHKEY-Bluetoot ... 157&sr=8-4

The only reason why I got this dongle is because as in the forum states, "Built-in Raspberry Pi bluetooth does have its limitations."

Thank You for your help, the software is awesome and hope you guys continue developing it for the safety of drivers all over the world!

Hi,
I'm having an issue with hands free calling.

I am have tried both internal rpi Bluetooth and a Asus Bluetooth 4.0 dongle.

Audio out via 3.5mm rpi jack
Audio input via USB mic (https://www.amazon.co.uk/gp/aw/d/B01LCIGY8U)

Using rpi Bluetooth:
When using this method I can connect okay.
I can hear the caller okay (no issue)
The caller can hear me, but sound is bad (sounds crackly)
Cannot display contacts
Cannot display call history
Cannot play music (A2DP)
(Need to double check last 3 points, but I'm pretty sure this is the case)

Using external dongle:
When using this method I can connect okay.
I cannot hear the caller.
The caller cannot hear me.
Can display contacts.
Can display call history.
Can play music (A2DP)

I really just want hands free calling
Any help is appreciated.
Maybe this mic is sh*t (I have a headset I can try tomorrow instead)
Thanks

Bluetooth dongle by Asus is based on the same Bluetooth chip like Raspberry PI built-in one. Could you please try to use another adapter? Our users recommend Panda Bluetooth 4.0 Adapter.
