mouse?

I have heard on some smart phones you could get a bluetooth mouse to pair and function with the phone. Does anyone know if this is possible with the dash?

Not that I heard of. What phone did you hear does this?

Yeah I couldn't find the thread I had read earlier. This was the closest I could find. I read somewhere that someone did get a bluetooth mouse to work with Excalibur. However now I can't find the article. He said the only problem he had was finding a mouse pointer program.

I was experimenting with something similar to his earlier today, although I desired the reverse method of control. I noticed that XP MCE device manager had a HID that was called Bluetooth Remote Control.
After a little search, I discovered a free application called Bluetooth Remote Control for Windows Mobile.
http://www.jaylee.org/remotecontrol/
I installed the application and was quite surprised that I could control my XP MCE laptop's Media Center as well as Windows Media Player with my HTC S620 (modded Dash). The application even utilizes the HTC display to display song information and also there is no line of sight requirement.
What I really wanted was to be able to control the PC's mouse and keyboard with the Smartphone. Not view the PC but just use the phone like a mouse and keyboard. The application has this ability (Screen Control) for PPC's but not completely for Smartphones. I was able to scroll up, down on a web page or application but that was all.
I installed FakeCursor and configured SmartToolKit to launch it from an extended keypress. Now I was able to move the mouse pointer on the laptop, a bit, and enter data via the HTC keypad. However, Fakecursor stopped sending data after it reached the edge of the Dash screen so I could not completely navigate the laptop.
If anyone is looking for a free remote control for audio/video application the application mentioned above would be a good start.
Any tips about the best way to use a Smartphone Standard without touch to control a PC would be welcomed.

Canbus Management

I'm new to android radio, having looked but not touched for a long time.
I have a 2015 Jetta and for my birthday my family got me a Burger Motorsports JB4 (Piggyback tuner), and an XTRONS radio (PX5 8 core 4GB unit.)
The JB4 unit uses the CANBUS to keep track of engine parameters while it modifies signals between the engine and ECU to control boost, fuel pressure, and timing. Officially BMS says it won't work if you have other devices connected to the CANBUS and say it is due to bandwidth issues. If the JB4 detects that it isn't getting enough information across the CANBUS it defaults down to a safer tune.
I've discovered that as long as the radio boots after the JB4 they seem to play nicely together, for the most part. But this means the XTRONS software loses lots of settings every time I start the car.
I'm looking for a way to control what and how much the Radio uses the CANBUS for, I think if I could limit it to steering wheel controls and reverse camera I would be happy, or even just delay the CANBUS connection in the car for 30 seconds. The other path would be to flash a ROM that keeps all its settings when it is rebooted but I haven't seen that issue addressed in the HAL9000 or Malaysk threads.
Is there a way to modify what the CANBUS module is looking for? Would other ROMS tolerate being rebooted better?

Hi Profsnakes,
I am currently working on modification of some images in canbus.apk file
I am not sure you can get more from your car by just modifying the software, it depends mainly on the canbus adapter you are using
Have a nice day

Thanks for the reply. Unfortunately, I don't know or understand much about the development side of this stuff. I've worked as an electrical technician for years and have a good understanding of how a Canbus works but not the programming or design side of the stuff attaching to it.
Rather than getting more out of it, I was hoping actually to be able to limit how much it used the network somehow. Even just reducing how often it polls the network. The other device I have attached requires a constant data stream from the ECU.
At this point, I have narrowed the problem down. While it would still be good to limit the bandwidth used by the radio. It seems the error I was having was being caused by the USB connection between the radio and the tuner when the car was starting up. So far disconnecting the USB when the car is off and reconnecting after it turns on seems to keep it stable. I ordered a USB "KVM" style switch that I'm hoping will keep me from having to open the glovebox all the time.
Heres what I've got going.

PX5 MTCD Android head unit knob remapping

Hi guys,
I have a android 8.0 head unit on my 2011 VW polo, I'm also using a carplay dongle,
The head unit has two knobs - a left knob that controls the volume and a right knob that controls the song currently playing (next & previous).
I would like to change the right knob's functionality - instead of moving between songs to act just as pressing up&down (just works better with carplay)
I've found that the knobs have the same functionality as the steering wheel buttons as shown in the picture below: (sorry for the bad quality)

}
Yellow ones are the same as the left knob
Red ones are the same as the right knob
I want to remap the right knob without losing the functionality of moving between songs using my steering wheel.
I've also found on the factory settings a changeable value named knob mode:
As for my understanding, 8.2k/15k ADC ports correspond to the steering wheel buttons,
I guess the other next option corresponds to the steering wheel buttons on the other side of the wheel (I only have left side buttons, so that's a problem for me)
My next option is the IO Ports, but I have no idea how to set them as I wish.
The head unit seller could not help me.
Any help will be appreciated

I think you're wrong.
The Knob mode is not intended for the Wheel Steering buttons. For this you have to enable the option "Steering wheel key assign" inside "factory settings->others", Apply and exit (reboot may required).
Now you should see the option "Steering wheel keys" inside "CAR" settings, and moreover you should have the shortcut in your apps.
From this panel you can assign the actions to the Steering wheel keys, and obviously it works only if your original steering wheel keys system is resistive. Otherwise if you have a canbus system, you need for a canbus decoder which needs to be connected between your canbus line and unit cables.
The Knob mode, is intended for the type of phisical button's panel your unit have, specifically for the volume encoder (rotating) object. Some panel come with various resistors, calculated based on the encoder hadware's type, so you should never edit the Knob mode, since it's properly set-up from the manufacturer.
To re-map the physical buttons on the left and right side of your unit, you just need to go in "Factory settings->Key study->Panel key study".

Op joined, got answer, didn't thank poster who answered. Typical.

Peugeot 508 with JBL amplifier cannot run Android unit, cut off the sound in 3 second

Hi, I bought Peugeot 508 with factory integrated JBL 5.1 sound system with already fitted Andoid (A-media, RK3188, 5.1.1, MTCE_MX ) already canbus decoder (no brand, just sign for 2008) connected to the unit.
All signals from the steering wheel and buttons are working. Wipers, fuel level, volume, clima, etc... So the canbus is doing his job, except for the audio.
I tried different ROMs factory, Malaysk, Hal9k, with different versions of MTCE_MX from 2.96 to 3.30, but the same result.
I found a video having totally the same behaviors as mine:
https://www.youtube.com/watch?v=7Eb2N_9NF2c
If I move the volume control I got perfect sound for 3 seconds than cuts off....so if I'm moving the volume up and down contentiously I'm never loosing the sound, but it will show on the screen volume up-down all the time.
I tried all manufactures and types in the CANBUS sub-menu but all has the same result - no sound or sound 2-3 seconds and cut out.
In my mind the canbus adapter doesn't send sync signal to the JBL amplifier and then amp is cutting the sound, but I'm not sure.
Cannot be too high levels of the signal, because I can turn the volume up to the end and still is keeping perfect sound for 3 sec and cut off.
I also tried to change the type of amp with lexia there are 2 types "other" and "RT5", both has negative result.
Observations:
1. Without canbus module is no sound at all when the unit is connected in the car.
2. With Lexia diagniostic utility test of the Amplifier is completed without any issues, I can hear all speakers and sub.
3. I tried to connect the Android unit out of the car with directly connected speakers without Canbus, and all is working fine.
So for me is 3 solutions now:
1. Check with different canbus module box, but looks like every different manufacturer is producing its own canbus modules... My Android device is having brand A-Media ((MX) MAI_XIN Shenzhen Mai Xin Da Technology Co. Ltd) and there is no any support I found.
2. Find diagram for the AMP to catch where the signal is expected
3. Find app in google play to emulate up and down volume every second
4. Find the file responsible for CAN audio and change it with working one, if any.
If someone knows what can be done, or just ideas... please lae me know!
Thanks in advance!

I have the same car with same setup. I had the same problem when installing the head unit. It's easy to fix. Just go to the "Factory settings" and select the same settings like on the picture.

The difference is:
Aircondition : type1
and you have MTCE_MX_V3.41_1 and I have 3.30.
I will update MCU and revert.
Also mine is RK3188 and your is RK3368.
Thanks a lot again, I will keep you posted!

Any news?
Is it working?

Question [SM-S901U] How can i change the bluetooth bit & sample rates and turn on HD audio in the dev options?

It wont let me change these settings, regardless of if im connected to a bluetooth device or not. Do i need to have other settings enabled/disabled before i can change the audio settings under the developer options menu?
I have the U.S model with the Qualcomm snapdragon chipset, running android 12 and One UI 4.1, in case that's worth noting.
Im not sure if these will be of any use but just for reference heres 2 screenshots of the menus im unable to interact with.
All other bluetooth settings between "HD audio" and "Bluetooth Audio Codec LDAC:"
I'm unable to change, even though i can open the menus and none of the options appear to be grayed-out.
Sorry if this has been answered elsewhere. Im fairly new here and android 12 as well (most recent android version ive used in recent years is android 8.0 oreo). still learning my way around.
thanks in advance for any help, answers, etc.

tldr: I’m no help, but I can confirm some parts.
I’ve got a pair of Sony WF-1000XM3. As long as the headphones are connected, I can turn on and off the HD audio setting and switch between SBC and AAC (they don’t support better standards).
My old Bluetooth speaker and a Jabra Evolve 65 don't activate this settings, so it depends on the Bluetooth version and supported audio formats?

Yes I can confirm that, same here.

It's as simple as connecting a headset capable of this codecs/options.
I think generally the best option would be selected automatically.

You can only initiate the changes for HD codecs when the bluetooth device is connected. Example, With Sony linkbuds S, I can select LDAC Or AptX. Once configured, the codec activates every time you connect the BT device.
