Keep Android and 3G Dongle always ON - MTCB Software Development

Hello guys I'm looking for a way to leave the 3G modem always on, even when the car is turned off.
any way to do this only in the software settings?
I really don't care to leave the android turned on in a fully standby mode.
The energy the appliance spends is much Less than the size of the battery in my car.
I'm using newest Malakya Rom. And the 3G dongle is connected in the 3G/USB Cable.
I don't want to make hardware modifications.
Thanks!!!

Justo to note. I stop, and leave my car many many many times in a regular day. And the 3G dongle takes about 1 minute to get Internet signal, so I can finally, get routes using Waze. Keep stopped in a car during 1 minute is not really safe here at Brazil.

I don't know about the 3G dongle. but the way I have mine setup the stereo stays on all the time. I have my accessory cable pluged in with the power cable. I have to manually turn the stereo on and off every time I get off the car but it's starts right away. and with an offline GPS app you don't have to wait for the internet connection.

Get a powered usb hub.
Use that between your stereo usb and the 3g dongle.
All you have to do is use a 12v usb car charger connected to your constant 12v then connect the 5v output to the usb hub.
That way when the stereo can receive data but the stereo isn't powering the usb hub or the 3g dongle.

But i have indicator light but dongle dont work. I have no connection. Its Huawei dongle btw

I have the problem that the dongle 3g not always connects on radio start. often I have to reboot the device. its a huawei too...

No charge when usb connection on car stereo

Hey everyone,
I'm having problems when connecting the thunderbolt to my Sony usb stereo. It asks me what I want to do and I choose charge only but it doesn't charge.
I use to have the Droid X and it worked fine on the stereo.
Anyone having the same problem?
Any hints or tips for this?

Your deck usb port might not provide enough power for the thunderbolt...but might have for the droid x. The usb addon for my pioneer never worked for charging when I had it installed. Just read flash dives, but that's just my two cents on the problem...could be something else.

I know some devices (like my Motorola dumb phone) will not charge over generic USB power (power and ground only), but if you use a USB "Data blocker" (grounded data pins) some of them will charge. This may be the same way... or it could be the whole requires more than just 5V to initiate charge without detecting data (meaning a PC connection).
You could try placing some MP3s on your SD card and tell your radio to "play" the usb drive and set the phone to automatically mount as a drive. That may do it, if not, look into the grounded out USB cable.
I just installed a lighter receptacle behind the stereo and ran up a car charger (not a usb charger) through the back of the dash to the car dock.
I was able to get the phone to charge via the USB port on my kenwood deck, but it was USB power, and discharged faster than it could charge.
It now reports charging AC, and charges normally. Cost $6 at radio shack.
I just tapped into the positive and negative wires that were already going to the original 12v lighter.
I'm actually having a reverse problem. My phone charges in my car stereo's USB slot, but the receiver doesn't recognize it as a USB drive. The phone doesn't even notice there's a USB connection, even though it's charging.
Oh well. It has AUX too so, no problem really.

I have the same problem, but I suspect that's because of that stupid "Verizon Mobile" virtual CD on the phone. I bet that's what your deck sees and can't find any music.
If anyone knows how to get rid of that partition without rooting the phone, I'd like to know.
In my case I have to use the Bluetooth connection. That works, but it doesn't give me the song information on the deck. Might have to revert to an old iPod for our music in the car.

With my old Incredible, my car stereo acted differently. It would see the phone and the phone would ask me to go into disk mode. After a few moments of scanning, the receiver would say "Invalid Media". I was also on CM7 for a little and I was actually able to get the receiver to play music thought it.
It's a Pioneer DVD player.. Unfortunately with the Thunderbolt, it doesn't do any of the abolve. It just says "No Device" and the phone doesn't even do anything except charge. Doesn't ask me to mount.
Okay I found a solution. I believe the problem was the Verizon crap that ran when plugged in. I installed The Perfect Storm Rom and now its charging fine.

[Solved[Battery draining while plug in!

Hello again.
I'm having a problem with my HTC evo 3d. My phone discharging while is plugin to an ac adapter or while is on my charging PC port!. This only happens when I'm using the wifi hotspot or USB tethering and Bluetooth tethering option.
My USB sync cable is branew since the i though the issue was my old sync cable but that wasn't the problem. I guess my phone using more power than what the ac and port are giving to the phone. I have to stop tethering and use the fast charger option to go back and re-use tether. But I kinda getting tired of pausing Netflix and sometimes downloads just to let the phone charge. What can I do on this situation that I have on my hands.
Thanks in advance.
[Solved]
I used the voltage control app from the market it fixed the issue and now I can use the phone and tethering at the same time without the phone discharging....

Charging with USB data pins disabled or disabling data connection

Hey guys,
I'm using my tablet in my car and have it connected to a Kenwood radio which has two USB ports. The radio can recognize the android device and changes automatically to USB as an input and then my steering wheel controls don't work anymore.
So as a workaround I bought an USB adapter which only connects the power pins. But with this adapter, the tablet is not charging. The cable itself is working as intended with another phone, so it has to be something special about the tablet.
Does anybody know if there is a way to use a data connection via USB to only give power to the Z2 tablet?
Man, somtimes I'm just an incredible idiot. The Xperia Z2 Tablet has a dedicated charging port at the bottom for which I already have a cable. So, I'm going to use that.
Sometimes the solution is so damn obvious

Possible to to connect Ethernet to Mate 20 Pro

Hi,
I just wondered if its possible to connecta an Ethernet cable to the Mate 20 Pro and use the phone itself as a USB modem.
I know there are loads of USB C to Ethernet connectors out there but they seem to be aimed at PCs.
Basically I want to turn my phone in to an hotspot via ethernet, then plug the other end of the cable in to a WAN port on a router, and use that router as the wireless hotspot if that makes sense. It's because I am moving houes and will have 3 week wait for broadband to be installed.
A Raspberry Pi solution could be an option. I don't know enough to describe what to do.

Ignore me!
I already have a WiFi extender at home, I will just turn my hotspot on and programme the Wifi Extender to rebroadcast the signal. When I am out of the house the extender won't work obviously but will kick in to life when I turn o the hotspot back on etc.

Question AA Wireless intermittent

I use Android Auto on my 2019 NSX with the AA Wireless device ( received a couple months ago).
It works great 90% of the time but every now and then the connection will drop playing Spotify.
Does not drop when using the USB cable connection.
Is there a firmware update available?
Thanks for your assistance.
do you have the smartwatch connected to your phone as well when this happens?
I do not have a smart watch. It will connect, disconnect, then reconnect automatically a few times a week. It never did this when I connected to the USB port via a cable.
Thanks for your help.
