problem with 3g connection - MTCB Android Head Units Q&A

Hi all
I'm using Joying rk3188 1024p with Huawei E1750 3g dongle.
My headunit is rooted installed stock rom and there is 1 USB starage for music.
When I drive my car and after 30~60 minutes 3g connection lost.
The icon of 3g signal disappear(Triangle shape) and there is no connection before I unplug and re-plug dongle.
I tried call-pppd script and wired external power to USB hub (5v 1A) and there is no luck.
Any comments or simple solutions will help me.
Thanks

Try with another dongle and/or another SIM.

Landline Adapter

Hi, i am looking for an adapter so i can plug my phone in via miniUSB cable to Landline phone and have it take n make calls over landline, any ideas? I had a google and a search through this forum but cant seem to find anything.
Thanks
Mat.
you dont mention what device you have
but only the Athena
can do any type of usb host
which mean other devices can only use it's connector for 3 things
1 be connected to from an usb host like a pc
2 use the audio wires for a headset
3 be charged over it
problem 2 is that
usb is a digital serial bus and landline is an analog system
so they cant talk unless a modem is between an analog old fasion modem
like 56K
and one which support voice input never seen one which
can do it over usb
Hi thanks for your reply i have an XDA Orbit.
so i guess no ethernet connection, or OTG usb. I will have a look at the athena though as this is my personal phone and i am looking for somthing for work.
Though how about usb over ditital networks and interfacing to ip phone switches ?
Thanks

can you get a modem to usb? & what about ethernet connections, or OTG usb.

ipphones dont use the real landline connection they use the adsl digital connection which is modulated on top of the old analog system

USB wireless keyboard/mouse using wifi

Well I've been searching for a while trying to connect the S3 as a laptop using MHL+USB OTG, but seems it is not possible or simply hard enough to consider other options. Several options have been considered:
1- Using BT keyboard/mouse is not always suitable since most of us use 2.4Ghz USB keyboard/mouse and it does not consider connecting HDD or other stuff.
2- I found an application that allows you to use your keyboard/mouse connected to your PC to control the phone, "takecontrol", take a look here:
https://play.google.com/store/apps/...NvbS5kcm9pZGNvbnRyb2wudGFrZWNvbnRyb2xsaXRlIl0.
Using this app you could also share an HDD connected to that PC solving one of the previous problem BT has.
But this configuration forces you to have your computer switched on... a bit useless if what you want is to connect the S3 as a PC instead of using an actual one.
3- After this I thought of using a wifi USB HUB, but hey! most of routers have USB ports, so why don't we use them instead of buying a new equipment? Then I realised it should work fine for sharing contents from a USB HDD but for USB wireless mouse/keyboard...
(those of you who have a BT mouse/keyboard but don't know how to connect the USB HDD to get "full" PC experience with the S3/S2/Note..., maybe it's still interesting this option)
So my question is if it is possible to connect a USB wireless mouse/keyboard plugging it to a wifi USB HUB. Maybe with an android app? what do you think guys?
I'm still thinkin about this.
Would be possible to use a wireless USB Hub, via wifi or BT?

3G dongle issue

Hi,
I have KLD rk3066 with malayks rom and huawei dongle.
I have disconnection while I am driving (the signal bars are displayed but the 3G sign dissapears).
I tried the script in the faq page, and I also bought powered USB splitter.
I still facing the same issue.
Is there anything else I can do?
Thanks.
May need to look at using a usb powered hub (or similar)

Compatible 3G/4G modems

Hello,
The modem that worked 100% of the time in KGL MTCB units, the Huawei E173u-2 doesn't work anymore.
The manufacturer sent us a list of modems that are - to say the least - very exotic in Europe.
Does anybody have a list of compatible modems? What modems do you guys use?
Do MTCD units support 4G/LTE modems or still only 3G?
Make use of an old phone, making wifi hotspot! - works best for me.
No need to buy slow sticks. Blackberry Q5 is very cheap - and LTE 4g wkan-hotspot is in.
Try the "chinese" umts stick for umts/wcdma that are sold within the headunits. these mostly are 7.2mb/s download. not statisfying, is it?
Yep, the UMTS stick is crap. I bought a Huawei E8372 LTE-WiFi-Stick. This one runs much better.
I tried a Huawei 3131H USB stick and it works fine (3G). The connection appears as a mobile 3g regular icon on the head unit. Sometimes the stick connects, but there's no visual feedback on the unit (still works).
Then I switched to a Huawei R216 (modem/wireless router with battery) with 4G, also works fine. The connection appears as "shared via cable" - 2 small overlapping computer icons. It also works seamlessly. You cannot connect the head unit to the modem wifi while connected via USB (makes sense and I don't know if there's any setting to switch from shared cable connection to wifi)
Hotspot with internet connection (from various phones) - works without a hitch and you can do it with an older phone connected to the USB for power, I tried with an old Samsung S3 Mini and it worked.
The Vodafone tech guys said that their stick modems may not be compatible with my setup, because they had people returning them after tying to connect them to tablets via cable. I suspect that's the case for the headunit too, so I didn't risk it - Vodafone Mobile K4607-Z (from ZTE) and Vodafone Connect USB Speed 6 4G (Huawei I think) are the ones in question.
Hope this helps.

What units do you guys have? Out of curiosity? KLD, KGL, etc?
GS (Xtrons)
Some one test the Huawei E367U-8?

Surely this has nothing to do with MCU version and is dependent on the ROM?
Zubie
I bought a Zubie. It plugs in to the OBD2 port and provides wifi to the car through my Verizon account.
In order to still use a bluetooth OBD2 adapter simultaneously, I bought an OBD2 splitter cable off amazon.
I love this setup.
DOES NOT WORK:Telstra Pre-Paid MF823 4G USB (ZTE MF823) (Unlocked via ebay code)
Only works if when initially plugged in, does not work when resumed from standby or swapped from wifi: HUAWEI E122
Also, There is a big difference for applications activity between a "Cellular" data connection and a WIFI connection (Tethered/hotspot). EG. Spotify set to only download on WIFI connection cannot differentiate between your home WIFI connection and a hotspot or Play Store set to update on WIFI only. This can become costly if you're on a small data plan.
Huawei e3372 (4G/LTE) works perfect when updated the MCU (MTCD_KDV1.82_1 Aug 26).
Initially I've tried with MTCD_KDV1.52_1 May 4, but didn't work.
but nevertheless, there's not 3G or LTE icon signal, there's a Network icon (two computers like MsWindows icon) like if it was an ethernet connection.
I've tested and it works at LTE speed. Cool! :good::good:
Only there's only one problem: This network connection is preferent over WiFi, so, to connect to a Wifi Nework i've to unplug the USB dongle. It's impossible to connect to a WiFi when the dongle is connected.
Joying posted a new 4G dongle, but looks like it works more as a wifi hotspot:

100% a hotspot, the unit is simply powering it.

I've actually got the R216 and I can't make it connect via USB at all - just using the wifi connection.
Could I ask what MCU you are running and roughly where you see it in the network settings?
Thanks!

hey, I have the R216 from Vodafone Romania and I just plugged it in in one of the 3 USB ports with a microSD cable (works on any of them, with no special settings) and threw it in the glove box. My unit is a HotAudio MTCD 5.1. As for the MCU, it worked with both the default one from May, and with the updated one from this forum (June, I think). Can't exactly recall the versions, 1.53 and 1.63 I think. The modem works with both cable sharing and hotspot simultaneously. The unit takes the cable connection as a priority from the modem (you can not plug it in the USB, but choose the Wifi from the same device). I also found out that in some ROMs, the cable net speed is vastly superior to the wifi one

Awesome - thanks heaps!
I have Vodafone Australia version, so probably similar. I think I have one of those MCUs and I'm using the June version of @Malaysk's great software.
Will have to check things out further - my unit has this thing where only one of the usb ports is assigned to be used with the modem, and I can't remember which one I plugged my usb webcam into.
Thanks again for responding.

In my unit's printed schematics & cables, the single shorter one is designated for modems (and has a separate port in the back of the unit). I just plugged the modem in the other 2 for curiosity. For HotAudio MTCD i think there are only 2 MCUs anyway, I couldn't find more. ROMs don't seem to matter, I went through 2 factory versions, 2 Malaysk versions and now I use a Xtrons one,no issues. If you can't get it to work, it may be the modem's firmware to blame.
Silly question, what do you guys use for the SIM card? Surely you don't pop it out of your phone and install it in the modem every time you go for a drive?

Separate sim. Here in Australia I am using a sim from Aldi Mobile on the "Pay as you go" plan.
Still waiting to find a working 3G/4G sim modem for the MTCD

Question internet with cable usb?
