How to improve GPS fix?(no root) - MTCD Android Head Units Q&A

My Xtrons PA7739BP came with an GPS antenna, which now is located on the dashboard right at the front.
Once I have a GPS fix everything works great, BUT, getting a Fix, that is the main problem. It takes at least 5 to 10 minutes.
This without having any Wifi or Data connection. Not tried yet when having my phone as an hotspot to give the unit data connection
Any idea how I can improve this?
Past weekend I had a trip, and after stopping the car for gas, fix was again gone. So I first needed to wait for my GPS fix before I could get going.
Very annoying.

To be sure that is not an window issue, I moved the GPS receiver outside the car. Just under my wipers (under de hood).
But still it takes a long time to get a fix.
As soon as I start my car, an extra phone i have inside the car start the 4G hotspot.So unit has wifi within 1 minutes. So unit should be able to use this to get a better and faster fix

Bluetooth GPS app

I wrote an app that tells me time to a starting line where the official start is based on GPS time. My app needs the best location accuracy and the time from the GPS satellites. To get DGPS, I need an external module and for that I bought a Qstarz 100XT which has WAAS capability.
I cannot find an app to interface the module to my phone or tablet. Here is what I have tried and what the problem is:
1) Bluetooth GPS - loss of bluetooth lock without re-acquiring. Totally useless in a race situation.
2) Bluetooth GPS Provider - time reported is system time, not GPS time. I can set the system clock off 5 minutes and all my GPS apps thing the time is off 5 minutes. Totally useless.
3) GPS Mouse - same as #2.
In addition I would really like 5Hz update rate which Bluetooth GPS Provider has but more important is something that works, does not lose lock, and reports the GPS time not the system time.
I have read like 100 posts here on xda and Googled it for hours. I posted on stackoverflow without success.
Does anyone know of an app that really works for interfacing with an external GPS and reports distance and time from the satellites and reacquires when it loses lock?

I use Bluetooth GPS 0.7.5a by Googoo Android in combination with an external GNS5870. This works like a charm for months now, using copilotlive premium, sygic (mock locations activated)

[Q] Disable WiFi below a certain connectivity threshold

I have a really good router, and a really terrible car. In the mornings I generally sit in my car while it idles long enough for it to heat up enough that my breath doesn't freeze on the inside of the windshield, which takes about ten minutes. Since I have nothing else to do, I generally browse the internet on my phone. I also have a good enough router that even all the way across the parking lot in my car, I still get some wifi connectivity. It is enough that the phone recognizes it's connected, but not good enough that it can load pages. Therefore, it always gives me "page failed loading" messages. I generally have to manually turn on WiFi for it to default to 4G instead. Is there any setting I can change to where it will automatically disconnect from a wifi network if it has below a certain connectivity that is higher than default?

MK809IV with Bluetooth GPS time issue

Hi guys, please suggest the direction to find an answer.
Use MK809IV in the Car pc project and everything looks good except initial time issue when there is no wifi connection to sync time (tethering is not always a solution here (no coverage or wife driving)).
I use one of the qstarz bluetooth GPS and Bluetooth GPS app to connect it to the system. The app shows on connect 1917 year every time but the month, date and time is correct.
The other app I use for navigation (igo) shows fix but always with 0 satellite in view.
The same GPS and the app on a couple of others android phones works well.

Wi-Fi dies when using bluetooth to listen to audio?

This is my second phone to have this problem. First was my old S4, now my S7 has the same problem. Basically, I want to watch YouTube or Netflix on my phone over Wi-Fi, and I want to listen to it on a bluetooth headset. But after a few minutes of watching/listening, my Wi-Fi connection always dies, I get that little exclamation point next to the Wi-Fi symbol in my notification panel, and the only way to fix it is to turn off Wi-Fi and turn it back on. It'll work for another couple minutes, then die again and need to be reset. Bluetooth stays connected the whole time and never drops. It's just the Wi-Fi that gets dropped. If I turn Bluetooth off and just listen via phone speaker or wired headphones, no problem, Wi-Fi can cruise all day.
The research I've done suggested that 2.4GHz might be causing a problem, but my network is 5GHz. Another suggestion was to switch the phone to a static IP address, that didn't help. I'd also read that Android has problems with IPv6, so I went to disable that in my router and discovered that it's never been on.
So, I found three solutions on my own, and none of them worked. Now it's time to reach out to the brain trust here. Does anyone have any idea what might be the problem? Vanilla S7, no root or ROMs. Thanks!

Have you tried the usual first step in troubleshooting, have you tried booting to recovery and wiping the cache partition?
You can also try flashing the stock firmware for your model number via Odin.

Stop watch from getting Location from Phone, without turning off Bluetooth

I've noticed that if my watch is connected to my phone via bluetooth, it will try to get location data from the phone rather than the watche's own GPS.
Under normal circumstances that's not a problem, however when I go hiking, I keep my phone in my backpack and it loses the GPS signal. That means the watch also loses location data and no longer properly tracks the hike (or any other activity where the phone might not have a GPS signal).
Is there a way to force the watch to use its own GPS even when bluetooth is on?
Turning off bluetooth on the watch fixes this of course, but then I no longer get notifications of text messages coming in while my phone is not easily accessible, which is kind of the point of the watch in the first place.
Maybe turning Off Location on phone ?
