I got a moto hx550 bluetooth headset with a2dp and want to pair it with my note 2. I am curious what sort of codec the note 2 will stream over bluetooth, whether it is sbc, mp3, or aac. Sbc is the barebones default, but the quality isnt very good. I also want to figure out what the hx550 supports, as there is little to no info. Ideally, both can support mo3, but the cheap mono headset most likely doesnt. I would like to test it anyway. Is there a way to see what codec is being streamed over bluetooth by the note 2 or a way to modify it?

Does the Car Dock not work with a Bluetooth Earpieace or Speakerphone?
Of course the Motorola Car Dock works with a bluetooth earpiece and I can only assume it works with a BT speakerphone. I use my Atrix in the car dock with a Motorola H790 BT earpiece every day.
Why would you think otherwise? The car dock would be fairly useless, if it didn't work with BT devices in your car....
Because when I uae it through google navagation no commands go through the bluetooth I don't hear anything at all

While I don't have my car dock just yet, I think your issue may be with your headset. Do you happen to know the brand and model of your headset? If your Bluetooth headset is not "A2DP" compatible then you will not be able to stream music or navigation directions through it.
From Wikipedia:
"Advanced Audio Distribution Profile (A2DP)
This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection.[1] For example, music can be streamed from a mobile phone to a wireless headset or car audio or from a laptop/desktop to a wireless headset.
A2DP was initially used in conjunction with an intermediate Bluetooth transceiver that connects to a standard audio output jack, encodes the incoming audio to a Bluetooth-friendly format, and sends the signal wirelessly to Bluetooth headphones that decode and play the audio. Bluetooth headphones, especially the more advanced models, often come with a microphone and support for the Headset (HSP), Hands-Free (HFP) and Audio/Video Remote Control (AVRCP) profiles.
A2DP is designed to transfer a uni-directional 2-channel stereo audio stream, like music from an MP3 player, to a headset or car radio.[2] This profile relies on AVDTP and GAVDP. It includes mandatory support for the low-complexity SBC codec (not to be confused with Bluetooth's voice-signal codecs such as CVSDM), and supports optionally: MPEG-1 , MPEG-2, MPEG-4, AAC, and ATRAC, and is extensible to support manufacturer-defined codecs, such as apt-X. Some Bluetooth stacks enforce the SCMS-T digital rights management (DRM) scheme. In these cases, it is impossible to connect certain A2DP headphones for high quality audio."
I am using it with a bt speakerphone, cruiser II and the navigate commands come through the cruiser or the audio if I have the fm on.
I use a Sony Receiver in my car which is bluetooth compatible. When I've used an iPhone and a Droid 2 with it in the past the audio streaming has been great, but I've noticed when testing it with an Arrive and with an HD7 it sounds like it's streaming at a low bitrate. It gets kind of crackly. Does anyone know if this is a known issue or if there is some sort of setting I can use to adjust it?
I've actually wondered if they dropped the bitrate on bluetooth audio streaming with the NoDo update, or remixed it. My memory may be failing me, but I swear I had a better audio streaming to my car stereo and bluetooth headphones on my Samsung Focus before the update. It sounds like the highs are mixed more sharply now, with missing mid/bass emphasis. This is to a nice JBL 8-speaker system in the car, and a pair of Sleek Audio SA6s via a Jabra 3030. Anyone else noticed a change in bluetooth audio streaming since NoDo?
Hi,
I have a Bagotte Stereo Bluetooth Headset, which works in Stereo Mode in Music Listening only mode in good quality...
See:
https://amzn.to/2V8bAdg
which claims to have a HD Microphone and supports Apt-X Codecs...
But now I wanted to try to change the Audio codecs to see, what are the best sounding Audio Codecs...
So I found this Android app:
https://play.google.com/store/apps/details?id=com.wikimediacom.aptx.checker
the Apt-X checker,
but after watching this video, which shows, how to change the audio codecs in the phone:
https://www.youtube.com/watch?v=zVK4UIHOEGE
And I can also change this in my phone....
But the Apt-X checker APP does not detect, when I have enabled the Apt-X codecs...
And I also hear no difference....
Also this app has bad review and saying it is a bogus App.... Hmm....
So how can I enable these codecs and test them out the best way with this headset ?
Are there any better Bluetooth testing Apps, that really tell me the used codecs and its settings ?
Or how can I find this out ?
Many thanks.
Regards, Stefan.
Xiaomi provides poor codecs support. Right now, Mi A2 Lite is using SBC codec only, while on Oreo we at least have had access to AAC too.

I just installed a good Audio player today and then went into the Developer mode setup and set the Bluetooth Audio codecs to Apt-X 48 Khz and 32 Bit
and then started the player. but after each stop it switched back to SBC 16 Bits 44 Khz....
So no luck with switching the Bluetooth Headset to APT-X, which my headset supports... Damn..
Also my BT Headset supports under Skype only 8 KHz sampling rate... I really can hear the difference between it and and normal
wired headset when I call the the test-echo Service of Skype... with the wired Microphone it is much clearer, than with the Narrowband
SBC codec with my Bagotte BT Headset...
So is there any other solution to get the headset to work with a Wideband Codec also in Skype and other Audio applications like Audio recorders,
which at least use a sampling frequency of 16 or better 44 or 48 KHz via Bluetooth ?
https://forum.xda-developers.com/mi-a2-lite/how-to/basic-aptx-bluetooth-audio-pie-t3891715
So, if you install Magisk on Andoid 9 Pie you will get ALL the Bluetooth codecs to work or what ??
I already considder installing a custom ROM , which does fully support the Wideband codecs under Skype Audio calls and other audio applications..
I would like my BT Stereo Headphone with APT-X to work with Skype with Wideband codec and also use my BT Headset for
Audio recordings with at least 44 or 48 Khz sampling frequency and not just the 8 Khz Mono SBC Codec that is really crappy....
Which custom Rom does this allow on the Mi-A2 Lite ?
How about the Lineage OS versions or MUI versions ?
Many thanks.

Before the phone (S9, Pie) used different Bluetooth audio codecs with different devices (AAC for car speakers, AptX for the headphones). But something happened 2 days ago, and now my S9 suggests only basic SBC codec for all Bluetooth devices. Manual change does not help (it always reverts to SBC). As I know there were no any Android updates in the last days. Can any suggest what happened with S9's Bluetooth, any ideas how to fix it?
Hello,
I was trying to switch the Bluetooth Audio Codec to Qualcomm aptX to be used with my SoundPeats TruEngine 3 SE wireless earbuds. I am able to select aptX when the Bluetooth is switched on,
but as soon as I connect my earbuds it switches by to AAC
I am certain that my earbuds support aptX codec ( Product Spec is available here
Had anyone this same issue? Is there any way I can resolve this? I just want to make sure it is an with the issue with the phone so I can be certain that I don't have to return the earbuds.
