We all know of our gps problems, not getting as much discussion is the compass which is just as bad.
I got a bluetooth gps as a work-around for the first issue, but what of the compass?
Is a a ROM which is considered superior in getting the compass working?
Or is there a way to bluetooth a compass to the phone, if not?
Figure since it's meant for outdoors it would have a magnetometer for compass apps. I've heard it both ways so far. Can somebody confirm that the app Bearing or any other compass app works with this watch?
NOT CompassX app, by the way, as it uses gyroscope/accelerometers to gauge direction, which isn't at all accurate.
Does not have a sensor for magnetic field. You can get compass via gps bearing wich sucks
I've added a few things to my head unit but i would like to add more sensors.
First was the external wifi antenna.
Then the extra ground from the display panel ground to the chasis.
And now im wondering how i can add basic arduino sensors.
Such things as:
Accelerometer
Gyroscope
Compas
Light intensity
Preasure
Temperature
Is it as simple as getting the sensor and adding it to the i2c bus or is there a better way?
Another thing is that I'd like to add a battery backup and connect it so that the os recognises it and gives me voltage and temperature. How could i do that ?
And lastly I'd like to change the right tune knob to a rotary knob instead of the spring loaded one. I just dont know if i could get a rotary one to replace it or if i would have to use a rotary encoder and an arduino to translate that into momentary on/off's.
Thanks
Stephen

Instead of arduino, maybe you can send UDP data to HU from another android device that have more sensors (i.e.: android smartphone): https://play.google.com/store/apps/details?id=com.ubccapstone.sensorUDP&hl=it

Cool thanks.
Im subscibed to that thread.
Does the android os sensor suite also include libraries for external sensors and would it recognise a well known sensor if i simply connected it using any of the busses?
As in: could i add a light sensor and have the os recognise that its a light sensor and to use that for diming the screen like a typical smart phone or what is the process to make that happen?

Id like to build the sensors in to the unit once i figure out a way to integrate but ill have a look at that

I guess you read the other thread.
How would the OS auto magically recognize your sensor and know what to do with it?
Do you really have a problem with dimming or are you looking at tinkering with this for fun?
I like Mekanix1's idea...
I would really like to see inclinometer and G meter working in Torque app.

What is this good for? Is it because of noise in the speakers? Because I have a noise and maybe this is another try for me to get rid of

Just for fun. Id like to add the same sensors that would be in every smartphone. I thought that the framework would be there and all i would have to do is find a way to make it happen.

Yeah that was another reason i was looking to do this.

On mine there was terrible emi interference when using the front mic and making calls over bluetooth.
Turns out it was because the ground plain of the display was inducing emi into the mic and feeding it through to the bt module.
I added a ground wire from the display board's ground to the chassis ground and it reduced the noise considrerably.
The next thing i did was disconnect the mic ground and just connect that directly to the chassis ground instead of on the display board and that fixed the problem.
For example

External usb sensors maybe can be easier solution than build them? http://www.yoctopuce.com/EN/products/usb-position-sensors/yocto-3d
However, i think the bigger problem is not hardware, but software: the Android OS of Huifei HU is not a "full and standard Android 4.4" so it is missing some features, like sensor reading capabilities...

I used an android sensor scanner on my unit and it said there was support for a variety of sensors but no input was detected.
I wonder how much one of those would cost to get and if android would recognize it.
I mean the unit does recognize different usb things I've connected.
It recognized a usb keyboard and mouse.
Just tried with an arduino connected via usb.
I uploaded a simple serial command called ping pong.
Basically when the arduino senses a connection to something on the serial it sends the text ping, and using a basic serial terminal app I got the text. Then responded with pong and it responded back. So, There is one way of having communication with an external device to do something useful.
The next thing I tried was upload a sensor suite app. If read a pressure sensor, humidity and temperature along with a real time clock.
Once connected it fed all that information to the serial program. I could see how I could add temperature and vibration sensors to it so that I could read something useful happening in the vehicle. Then I could just add sensors to the drive-train and have a way of monitoring. lots of interesting things to mess with.
Now its just a matter of using processing to create some sort of GIU. Arduino i can play with but processing is stil la mystery to me
I have been looking into this as well, but more as a future plan, as I don't have my HU yet.
Would be interested in getting direct sensor I2C support, shall start doing some digging to see how it's dune in regular phones
Did anyone come right with integrating external sensors to these HU units. Would love to use Torques inclinometer functions with an external accelerometer
Hi all,
Is there any app that can be used to detect movement on what is being displayed on the screen. So not using the front or rear camera.
The use case is a wireless endoscope camera, you connect to the wireless signal and it streams the feed direct to your phone (not connected to internet, just 30m away from the transmitter box). I want to then leave my screen open and if there is any movement on the screen for it to alert me.
I understand it will drain battery having the screen on for hours but I dont mind that, its for watching wildlife.
There is no app available that will connect to my endoscope camera that also has motion detection and the only way I can think of getting this to work is having a second phone pointing at the first phone and have the motion detection on the second phone haha. If i can do it all on one phone that would be great but not sure if there is any app that will notify me of changes in the feed of an app, or change of the display.
Any ideas?
Also forgot to say the phone is rooted (Samsung S8) encase that helps with the options
Problem jeep compass with android Hi, I sincerely hope that you can help me, I explain, I put a new browser on the jeep compass, (android) but I have problems On-board computer language goes to Chinese (I managed to put it in English and I can do fine) but the parking sensors recognize the image, you see but you can't hear the audio. The car doors when it locks for the children in front with the unlock button I have to press the button again but before that I just opened my door, on the navigator there is this option but the item is not checked. Mcu of the navigator and this k (7706) 90 c9 k1 ca (all) amp By chance, do you think there are some updates to get these things working again? thanks a lot
