Redmi note 8 pro - FM radio - mono !! - Redmi Note 8 Pro Questions & Answers

Friends, I have a problem - FM radio (RN 8pro) When I plug in the headphones (as an antenna) - the headphones play stereo. But when I use BT headphones, the phone sends only a mono signal to the headphones. (If I use Xiaomi mi max2 then everything is OK - same procedure - same headphones). Internet radio and players in BT headphones are stereo. In both cases, the headphones are like an antenna in the mobile
So I did the factory settings and then wipe, unfortunately FM radio when playing bluethooth playing mono. Perhaps some update will fix what you have RN8pro really plays in bt headphones stereo? Easy test, play the same station as internet radio and then fm.
Sorry for bad English, maybe you will understand the problem.

There is a setting for bluetooth audio to use mono in accessibility options. See there if that option is turned on.

The problem is that only FM radio over BT plays mono. Other players, youtube, play stereo. The problem will be the transmission of the stereo signal to BT from the FM radio. Everything is OK with MI MAX 2
RN8pro + headphones (antenna) FM radio- BT headphones - MONO,
MI max 2 + headphones (antenna) FM radio- BT headphones - stereo,
at identical settings and apk FM version

cable headset - AVRCP?

is there possibility to use cable headset like BT headset with AVRCP?
BT stereo headset are too big and not cheap.
I would like to control mediaplayer from headset
I do not need A2DP because I need only to listen audiobook, not music, so quality isn't so important.
Mono BT headset (I have jabra130) doesn't work with audio streaming on my Himalaya, and they doesn't support AVRCP profile.
any idea?
AVRCP is a bluetooth profile. If your headset is not bluetooth then it will not have AVRCP.
maybe something similair?

haven't met with any solution so far.. simply these devices haven't anything to control with excpept the radio waves.. it has only jack/etc. with these you cannot control anything.
Some headphones has an additional button which can be used to answer talk. Jack connection has additional place to use it. is it possible to catch pushing this button programmatically?

Can be FM Radio played via bluetooth?

I suppose we still need to plug in headphones to serve as an antenna, but anyway, is it possible to redirect sound from FM radio to bluetooth? I would like to use my BT headset when on a bike.
Thanks!
I purchased a bluetooth headset to use whilst on my bike and the FM radio doesn't work through it :-( as soon as you plug the headphones in it disconnects the bluetooth headset. I was a bit gutted as I like listening to the radio but considering the reception is a pile of crap I listen to last fm and my media files.
hope that helps

Car Dock and Bluetooth?

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.

Problem With A50's Bluetooth audio playback in cars and other devices

While playing audio on Car Stereo via A50's Bluetooth, The Audio got crackles and skips, even in receiving phone calls,
I have tried changes in developer options in Bluetooth menu, and also disabled battery optimization for Bluetooth but nothing changed :crying: Similar situation while playing in JBL Bluetooth speakers
At other side my old sony Xperia C3 D2502 is working awesome on same car Stereo.
Same problems
If you use powersaving mode disable it
Maybe the problem is from this option
You didn't mentioned which rom and baseband. I use BT with Anker BT headphones, Roidmi2S and used it with Roidmi1 and a Yatour Car unit without any crackles and pops. I'm on May update, XXUASE3, OXM CSC.
