Not recognizing Bluetooth device - MTCD Android Head Units Q&A

Hello guys, I ran into a little "trouble". Bought one of those chinese bluetooth footwell led lights, and they have an app, happy lighting, it works well on my phone because my phone and my tablet too are able to find and connect to the bluetooth channel of the lights, but my HU's bluetooth cannot find them, neither through the app nor with the original in built bluetooth scanning interface of the headunit. It would be really nice being able to connect them with my unit via bt and use the app to set the light color and intensity directly from my HU and not having to take my phone out everytime I want to do something with the lights. Notice that I have a 4gb px5 mtcd unit with MD725 bluetooth and Hal9k mod installed. Thank you.

Hi, Did you ever find a solution as I have the same problem?
Thanks
Baz

I have the same problem.
I have this:

Hal9k and Dasait PX6-Max6 with RF210 bluetooth module.
It's correctly selected in the factory setting bluetooth module setup (I tryed all model options).
I can pairing OBDII and LG Phone but I can't recognize the bluetooth lights, it's not founded in the available devices.
If there is no solution I will buy an external USB bluetooth.

[Q] Android Car Stereo Head Unit massive problems

Hey there guys!
I bought a Unbranded Android Car Steoreo Head Unit and it went pretty good in the first place.
After i installed spotify and downloaded music, once the Wifi wasn't availiable anymore, spotify told me that the USB-Storage is no more there (but it is).
I thought a upgrade would solve this so i googled and found this Thread:
"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit
As my Radio says its also a AN-21 U i thought it will work.
This is my Radio by the way:

}
So after updating the MCU it lags a little bit and the volume-knob and the +/- knob is changed with each other and not responding proper either.
I also tried to update the System but activating this just boots up the device saying update start and update end at the same time, not taking any affects.
Software System Reset is not solving this, and im not abled to enter the boot menu (By pressing power on + vol up butten (i tried both knobs after MCU update)).
Do you have any idea for what i could do? I would really appreciate your help because im not able to solve it myself.
Thanks!
PS. Sorry if this is the wrong area

[Completed] can't make calls with Bluetooth headset

hi.
i have UMI Super for about 4 months.
until now i was able to make calls with BT headset
suddenly, i don't know what happened, even when the BT is connected to the device i can't make calls via the BT headset.
i see that the problem is that the "phone audio" is unchecked

Greetings and welcome to assist. Have you tried unpairing/resetting the bluetooth device or factory resetting the phone ?

I can not connect to a BT device

Hello people, I'm trying to connect the stereo to a special BT device of the car that I use to tune, with this device I see specific gauges and I can configure the original ecu of the car for whatever I want, with the cell phone I managed to connect without drama, but with the application from the stereo I can not, does not even recognize the BT signal of the device, even a friend with an iPhone the same thing happens, what could it be?
The device is a jb4.
Thanks!

No. The built-in bluetooth is for phone calls only.
Use USB devices for tuning instead

Oh I see, there is any way to change that with software or change de BT module on the unit?
I just found out that the device I want to connect to is of type BLE (Bluetooth Low Energy),
Any ideas?

Question USB Network via cable

I have a question.After an upgrade of my head unit with a PX6 I have no WIFI or Bluetooth. The question is, is it possible to connect the headunit via USB-Ethernet adapter direct via UTP-cable to my router in-house. I can realize a test setup for the unit in my office, but am not sure if this will work? An experience with this setup?

If you have a PX6 you are in the wrong forum.
If you have FYT now after your PX6, then the answer is: No, this will not work. The USB stack is blocked to only allow the "FYT approved" USB devices and a USB ethernet dongle is not one of those devices.
I'm using an FYT/Atoto device with USB-to-ethernet dongle. It won't work while you're using USB debugging however.
If you're in developer options, once you select the second option, it'll disconnect your dongle.

Question Joying + Sennuopu DP-X10 DSP problem.

Don't know if anyone has experienced similar? But I recently fitted the DSP unit and used toslink/optics output from the HU to the DSP, and I am using the STD amplified output from the DSP unit to the speakers, audio from a USB drive works perfectly but on watching my first film with this setup I found that I was getting audio drop-outs in the quiet scene but only the four speakers and not the sub which is also run from the DSP unit but via an RCA cable to another amp, I have tried so far several different video player apps and its alls the same, but some are worse than others, it's almost like the audio feed is cut during the quiet passages, not yet tried another toslink cable but in my mind if this were bad there would be a problem with normal audio playback? Any ideas?
Post details of headunit, including Android system information including MCU version
The Joying unit is 10.1" SKU JY-UQS10N4G-H and I have now attached a pic of the MCU version etc.
