Hot Audio/ Dasaita PX5 4G - Anyone got Blutooth or Usb tether working? - MTCD Android Head Units General

My friend and I both got this head unit for our Honda Civics and we cannot get Usb tether or Blutooth tether working. I have a Note 9 and he has a 2 year old samsung phone but not sure what model. The head unit does not detect the connection when the phone is set to USB or bluetooth tether. Standard bluetooth works fine and syncs fine.
Is this not supported on the unit? Has anyone gotten it working?
NOTE: We have both updated the MCU to the latest 3.06 and the latest update and he tried it on an older mcu also.

I use wifi tethering.
No bluetooth tethering is supported as bluetooth is controlled by mcu

I need help understanding how bluetooth works on these MTCB HU's.

I've searched and looked, and I can't seem to find a complete answer to exactly how the bluetooth works on these things.
As far as I can tell; there is the native bluetooth manager that's built into Android, and then a Bluetooth app. Seems like the app is used to make calls and stream from the phone?
I've also read that there cannot be an OBD2 sensor and a phone connected at the same time? I remember reading somewhere that's because Android doesn't actually handle the bluetooth itself, so if I were to get a bluetooth dongle, would that fix this?
FYI, I have a joying headunit and I have been using the Torque app w/ a Bluetooth ODBII adapter and received calls while both are connected. But yes the Bluetooth profiles that come with these units are very limited and basic.

What is your process in getting them to work together?

I remembered that I had another BT OBD2 adapter. I was using this one and couldn't get it to work, https://www.amazon.com/dp/B011NSX27A/ref=cm_sw_r_other_apa_F0mqxbPZDQSQ5
I then pulled out my old one, (not this exact one, but looks identical) https://www.amazon.com/dp/B00EQ57BE8/ref=cm_sw_r_other_apa_b8mqxbA6SEVRV and now they both are working together.

Is it possible to get DashCommand working on these units? I like it better than torque.

Sure no problem, and what I did is just buy a self powered USB hub and stick an additional Bluetooth dongle in there (android compatible, costs about $4) and pair with both.
Never had a problem with any of them
Hello,
The BT module in these devices are not an internal device, rather an external BT chip. There is no direct data line between device and BT chip. Basically they send commands and share metadata over serial port. Thats all about so dont consider it is a native bluetooth device.

Bluetooth and HotSpot problem after Phone update to Android 8.1

I have an MTCD PX5 unit using SVA ROM Android 6 and I have been using it with my Phone for calling over Bluetooth. I am also using WiFi HotSpot on the phone to share the Internet Connection.
After the phone has been updated to 8.1 (it's a Nokia 6) Bluetooth only works well (not perfectly) if the HotSpot function is disabled. When enabled, the bluetooth connection is lost after I make the first call (which fails actually, the sound moves back and forth between the unit and the phone).
Does anyone else use a phone updated to 8.1?
Thanks.

noob question regarding connectivity on headunit

Hey everyone,
My apologies if this is a really silly question, but I'm new to these headunits and was just wondering how network connectivity works.
Assuming the headunits get network connectivity from my android phone, does it do so by connecting to my phone using my phones wifi hotspot? Does it use bluetooth to trasmit stuff like album artwork?
More importantly, does it auto connect to my phone everytime I start my car? What if my hotspot on my phone is turned off, do I have to manually turn the hotspot on everytime?
I've used Android Auto on the Pioneer units and it just pairs up automatically so I thought I'd ask here how these PX5 and newer PX6 units work.
So many questions. Thanks fellas!
Bluetooth connects automatically to your unit once you switch on the unit...(if you have the bluetooth enabled on your phone and you had already paired to the headunit)
With respect to the wifi....you have to enable hotspot on your phone for the unit automatically connects....but you can automate it by means of tasker or any other task manager on your phone in which when detected bluetooth connection to the car bluetooth enable hotspot...or as I do...I use a NFC tag to enable my hotspot.

Great info thank you! I'm a heavy tasker user so that's a great option. I also have some NFC tags laying around as well! Thanks again!
I guess that also leads me to my final question, is there any difference between tethering wirelessly or tethering over USB? For example album art or anything? I usually plug in a USB to my phone now so it's not a big deal, just wondering if wired has any benefits.

I can't get wireless android auto working on my PX6 MAX 10.
I have the Bluetooth connected to my phone and my phone connected to the head unit's hotspot but nothing happens.
Works over wired though...

Same here, any suggested solution?
pretty sure it doesn't support it. try using headunit reloaded app instead, but its still a faff to get working

Dasaita wifi & bluetooth connection issues

I have PX6-HA5393-MAX10-CP updated with the VIVID10. Loving everything about that, however I purchased a Cobra SC201 dashcam with 5.0 Bluetooth and dual band 2.4ghz & 5 ghz wifi. My head unit cannot recognize either of the dashcam's Bluetooth or wifi networks to connect. The dash cam is visible and accessible with other devices such as phone and laptop. Only the head unit can't detect the dashcams wifi or Bluetooth networks to connect. The head unit is 2.4 ghz wifi only and the dash cam claims it's dual wifi (2.4/5.0 ghz). Both claim 5.0 Bluetooth. I have tried manually adding and connecting to dash cams wifi using different encryption keys with no success. Same issue before update to VIVID10 also.

- The Bluetooth is crippled and only works for phones and certain obd adapters
- The max10 can't do 5ghz... only 2.4
- The camera software will not do wifi cams.

Bob,
Thanks for the follow up! Has anyone been able to successfully bypass the internal wifi/Bluetooth with USB wifi/Bluetooth adapter installs on these Android head units. I've read rumors of wifi bypass of others that know someone, but have yet to find any helpful links. Also not sure I follow regarding the camera software not doing wifi cams. Are you referring to Dasaita's DVR camera apps?

As far as I know... yes. The app is trained to look for cams on usb and on the dedicated dvr cam plugin. I have not been able to get it to look elsewhere for cameras.
From what I understand, some people have had LIMITED success with usb bluetooth adapters. Some have managed to get them recognized, but then they operate in the same crippled fashion. The bluetooth regardless of what bluetooth system you use, will only recognize phones and some basic obd2 adapters and as far as I know, no one has been able to work around that.... and this is not just Dasaita... but pretty much all of them.
would rooting fix this limitation?
Bump - anyone out there was able to get Bluetooth for anything other than phones/OBD devices to work with any of these Android head units?
I have tried three off-the-shelf Bluetooth dongles and playing with the BT "drivers?" in the list for BT under Factory settings (i.e Head Unit > Settings > Car > Factory Settings > BT).
No luck!

No, you cannot. See above posts.
UIS7862 FYT based units work, including BLE.
