[REQUEST] App for Audio via Mono Bluetooth headset

I'd love to be able to send audio (FM Radio, Sound player, podcasts, etc) to my mono bluetooth headset.
I have a Scala Rider headset in my motorcycle helmet, and I'd love to hear music from my Galaxy while riding.
I found "Super BT Mono" in the Android Market, however the free version doesn't seem to work. It doesn't do anything other than show an icon in the notification bar...
So, is this even possible?

possible yes
quality will suck
back in the old days, when they did not sell single sided A2DP BT headsets, many programmers created apps to send audio via BT to non A2DP capable headsets.
but not sure if any developer is going to take on the challenge, as it's so easy to buy a single ear A2DP BT headset now in days

I understand about the quality, and am willing to live with it.
With regards to the headset statement, trust me, the motorcycle community will love the developer of this app.
The SCALA RIDER Bluetooth headset attaches to the motorcycle helmet. So we can't just get any A2DP single ear headset. We're stuck with this.

anyone? please?

I'm putting together a simple program that will do this. FYI, it will be Froyo only.
Might be a couple weeks before I can get around to it though. I'm swamped with work at the moment, and I'll be away from home for the last two weeks of September.
It will probably be free on XDA. Might ask 99 cents for it on the market.

That is truly awesome!
I really appreciate it, as I'm sure others will!

I'll put it on my task list but cannot make any guarantee on when I can get started on this.
I'm currently working on a fix to get stereo FM radio, but while working on this I found lots of interesting stuff on all kinds of things audio related.

This is what Im looking for and cant find. The music plays in the ear piece during phone calls fine so seems like it would be easy to fix.

I've been looking for that as well. I used BToggle for 3 years on my WM5 HTC wizard. and was REALLY disappointed when I got the G1 and found... what?? NO BToggle!! so I bought a stereo A2DP headset. but with 5-6 hrs play/talk time = workable but less then happy. then I found, tested and bought Super BT mono shortly after it hit the market and use it alot!! only thing is now I miss the notifications "Pushed" to my non A2DP headsets. and this is what I want.
I think it can be done by changing parts of bluez but I dont know what yet. if anyone can point me in the right direction I'm willing to stumble my way through.
Peter.
running a G1 with CyaogenMod-6.0.0-DS
(I have 2 jabra BT250's, 2 jabra BT2050 headsets and 1 stereo BT A2DP headset)

Sorry, forgot about this little project. Put together a first release today. Find it in the market: BTmono by me. It's free. Detailed post later.

nice app
i tested it on froyo and have the following problems:
*) when using skype, it always changes back to normal phone speaker, i have to start your app again and press yes a few times, to route back to BT-headset again
seems that some actions switch it back to phone speaker
*) microphone of bluetooth headset is not routed yet, i hope this is also possible
but thanks fo the app, i hope it will work fully soon.

Awesome, Thanks! I'm going to take a look at it over the weekend.
My first proposal to it would be to have a small widget allowing to turn BTmono On/Off with a single press of the widget.

Hmm...sounds like Skype is trying to manually set the audio routing itself. Not sure if there's much I can do about that.
As for the microphone, I hadn't really considered that. I was thinking of this as purely a means of getting audio from the phone to the BT headset. Does Skype not work with a BT headset using the standard headset profile?

Ya, a widget is definitely on the to-do list. I need to add that to the market description. I wanted to get the basic functionality out there for now, and then add on over time. I probably wouldn't even have made it if the existing apps on the market weren't ridiculously overpriced, hehe.

Peugeot 407 rockchip PX3

Hi,
I've installed a new android headunit today. Running android 7.1 out of the box.
I have a few problems with it and a few thing I'd like to know how you do it.
Problems:
- Not all buttons work like they should. Temperature adjusting works fine but changing the air outlet on the passengers side doesn't.
- The car settings app is doesn't work. The toggles go from on to off and back...
Question:
- I'd like to use bluetooth tethering for internet, but that doesn't seem to work. the bluetooth settings look different and I can't choose to use the internet connection. Usb tethering would be a great alternative but I don't thing its available.
The only other option would be to use the wifi hotspot but I hate the fact that I need to switch it on and off all the time.
Hopefully you have a solution for these problems.
Thanks, Frans

I've just installed an Erisin head unit with Android 7.1 in my VW Passat.

My solution for tethering was to use the wifi hotspot on my Nexus 5X. I've used Automate to enable/disable the hotspot when my phone connects/disconnects to Bluetooth so I don't have to switch it on and off all the time.
Overall I'm pretty happy with it. Everything works as it should. I've replaced the default launcher with Car Launcher Pro which seems to be the only car launcher specifically designed for use on an Android head unit rather than a phone. I think it looks a lot better than the default one.
I've installed Waze and Spotify which are now linked together so I can switch between the two really easily. I'm using TuneIn for the radio, but my mobile signal sometimes drops out so I'm tempted to buy the additional DAB unit.
The only real issue I'm having is some slight buzzing interference when the engine is running. It's not terrible but I'll be looking into how I can earth the head unit better to try and suppress it.

Hi,
Do you have found a solution for this problems?
I'm thinking buy an Android head unit for my Peugeot 407, but I'm afraid that many options doesn't work, without original screen...

Hi guys,
I've changed the oem Head-Unit of my Peugeot 407 with a new PX3 with Android 7.1 and all main functions of the original system are ok.
Original Head-Unit was a WipNav (RNeg) with a 7" color display.
Now with the new Head-Unit set I can controll the dual zone clima (all controlls, pilot and passenger) and consumption indicator.
Some pictures at below...
What's your problem for the controls or buttons?

Hi trudtilp
Thanks for the photos.
I appreciate if you can answer a few questions:
- The unit, show external temperature, as the original screen show?
- Are the car messages displayed? Like "Low exterior temperature", "Front left seatbelt open", "Doors open", "right headlamp failure", "esp malfunction", ...?
- Original parking sensors are working? Beep and graphics or only beep?
Thanks in advance!

Hello everyone, I'm very interested in this because I would also like to install a head unit: the latest version androïd 8 on my Citroën C5 (RC_) (of course the screen should be adapted ...)
I ask myself some questions also about the sensors of recoil because the car has 8!
I know there are interfaces (look for "DanyMecano" on Youtube) but no way to know if this interface can accept as many sensors
And finally, my car is equipped with amplified JBL sound ... I saw that there were JBL CanBus decoders for Toyota (Aliexpress) but again, nothing for Peugeot 407 (or C5 with the same configuration)...
I'm French so I use the Google translation and I apologize if you do not understand everything!

As I know, JBL sound on Peugeot 407, works great with any canbus, also with the old versions that do not support reverse parking sensors. In a Spanish forum, there are an user who confirm that.

Ok I'll watch this thank you very much
#EDIT:
Do you have a link please?
I just watched 10 pages in Spanish language and I did not find anything ...

Hello everyone!
I found some information ... In ".es" as Peixeiro said!
A sale (too expensive) but the first info is very clear! :
"With this equipment, functions are not lost.
The steering wheel controls, vehicle information, parking sensors, climate, even the JBL system are retained.
With Android 7.1"
I also found a Chinese seller (Seicane) who gives an interesting info in his description, it say:
"Please note: this unit only can support your original car's reversing radar if your car's origin CD is a small screen less than 4.3 inch, then this unit can't support your car's reversing radar."
Below there is a photo of the RD4...

I use the custom setting, and adjust the bands below the line. However you cannot use the Bass or Virtualizer with the speaker. The speaker is too small and weak for those adjustments IMO.

Coming from v20 OP prettuly news to me is there any audio mods on this device? Btw im root..missing dolby atmos...is there any magisk sound mod work so far...and yeah would like prefer Bluetooth mod...since i only got Bluetooth headphone...

I'm missing Atmos as well. You may want to look at Viper4Android if you're rooted.

Yeah absolutely! Just installed viper and work the way should work...i assume that dolby not support pie at moment but i guess viper work for me now...

I'm on OOS 9.0.5 I didn't notice it doing anything to change the sound signature.

I'm still on 9.0... Tmo... I notice that it works on some streaming apps but not all. Works with Gmusic for sure. It does work on speaker as well. Not nearly the best EQ but it's usable.

I just got the T-Mobile 6t and I came from an LG G6 . And I noticed a big difference in sound quality in Bluetooth.
I had to recalibrate my car stereo eq settings in my car.
To me it's a downgrade in audio quality. Less bass and just doesn't have the umph. anymore.

Same here...came from v20 Bluetooth audio huge difference... volume is not that loud via BT i has dolby Atmos on v20 and sound amazing compared to OP...i used Viper to increase volume but seem it dont do anything...looking for a way to increase volume...

I didn't install yet but to involve in the discussion, for me compared to my nexus 6p it's a noticeable difference with the Bluetooth, it's better then I had before. Also via Android auto it's better quality then I had before.

I came from my trusty dialy driver the OG Moto X Pure -Rooted - with Sauron Audio Mod and Dolby Atoms EQ. The sound is phenomenal through BT even with the outdated codec. I hope to get the 6T to that level and even better. Patiently waiting to root my TMO Variant. On a side note; the sound from the 6T is pretty good through my gen1 QC35s.

You may have use your preferred Android file manager. Go to your Downloads/XDA Forums folder and install from there.

No prob!

Installed non root tmo.
It MAY be doing something but I can't really tell with the speaker...using headphones I can tell more(bass effect works etc)
I need to pay this phone off before I can root it LOL, that's a new one........just got it with EIP.
Viper is only reason I see the need to root tho. This phone is fantastic. Coming from s8.

I don't notice a difference, using Spotify or YouTube

After you install it.. Go and switch off the battery optimize for the app so it won't stop when playing music

These tweaks improve quality without any effects, it's just better options for output
V4A it's equalizer who work after these options. So if you want, you can combine.

In call volume
Hello,
Thank you for this wonderful mod, it has increased the overall volume, but the in call volume is still on the low side for my tastes . Could you please be so kind to tell me which line I need to modify in the mixer_paths_tasha.xml to increase it more?
edit: I mean the in call volume coming from the phone, not the earphones
Many thanks

I'll see what's the problem with psp emulator
Tested emulator, seems like works fine

I think there is an audio delay between 2 speakers and because of that, sound is distorted for me...I am talking about dual speaker mod. I compared with my other phone, which has same stereo mode (meizu 16th) and playing the same track was clearer, without any lags or latency...

AndroidAuto low volume

Does anyone face issues with low volume or lack of audio quality when using android auto?
I mean sound is ok, but its not as loud as other devices i used with AA.
I have tried the internal equalizer and dolby atmos, it helps a little but still not the same.
I have also tried the app EqualizerFX and so far seems better but not 100%.
Do you use any other method or app for this.
I am on the brink of rooting and going for Viper, but thats my last resort

i use poweramp pro ... it boost volume and bass for my buds - works a treat and it downloads the album art and instantly adds it to the track - quite nice

Have you upted the Bluetooth setting to loud.

1. Bluetooth on the phone has its own volume setting, I hope you pressed that volume up button on the phone, then said "OK" to earpiercing warning, and then pressed volume button up again until you reached max
2. Dullness of sound cannot be cured with any settings on the phone - in Bluetooth original data just streamed to the car (being compressed/decompressed along the way)
3. You can still play with audio setting to affect headphone jack quality - it helped me.

yes i know that.and yes that was basically the first thing i did.
and btw this issue with Android auto is not to do with bluetooth or jack.. it uses usb dac to stream auto and control to the AA interface.
anyways, as said Viper4Android sorted my issue, as it processes audio differently to the stock audio processing.
same as poweramp, has its own audio processing, also for usb dac
