[ONE General] CravingMender9:
Hey all,

I wanted to use my new OPO (without an extra SIM card) as a permanent slave to my original phone, and as a permanent fixture on my car as a car-puter for my 2005 Accord. I have to say, I am pretty impressed with the phone, and where I've reached now.

Hardware required:

1) OPO (obviously)

2) Main phone (In my case, my Note 3)

3) Car with Bluetooth Head Unit (depending on usage)

4) Cheap 7$ OBD2 Bluetooth interface from eBay

5) Raspberry Pi + RasPiCam (for backup cam)​

Software:

1) Torque for getting data from OBD.

2) Navier HUD Free (For some cool HUD Effects for my car ;))

3) MapFactor Navigator for free Offline Maps and navigation

4) Google Voice + Spare Phone (didnt want to spend on another phone line)

5) Tablet Remote ()

6) Tasker

7) fqrouter [to be discarded and replaced with WiFi Tether router]

8) Tablet Talk

9) RTSP Player​

Modules:

1) Wireless backup camera

I used Raspberry Pi with its camera module to use as a backup camera.

The Pi fetches the video and transmits it as a live RTMP stream using nginx web server. I can then see the stream play on my phone.

I use fqrouter to create a hotspot between OPO and RPi to get the live stream without losing tethered wifi connection with my Note 3.
​

2) Navigation & Car stuff

MapFactor Navigator free uses OpenStreetMaps to get free navigation to your phone. No need of a separate GPS unit.

Torque has the ability to connect to my car's OBD2 interface. It also has a HUD functionality which I thought was cool :D

Can also use Navier HUD Free for HUD displaying speed and navigation.​

3) Communication

Now, this one was a bit tricky. I wanted it to be connected with my phone. Since I had unlimited 4G LTE data from T-mobile, I had to leverage that somehow. I couldn't just use tethering as tethering isn't unlimited (now found a workaround for that too ;)). So I wanted to use Wifi Tether only for Google Voice texts and rare phone calls.

Communication involves multiple things:

a) Receive Phone and Text

For this, I used a fine but no-longer-supported app called Tablet Talk. In the future, I'll try to develop something for myself. For now, this one is good. I can send/receive msgs that I get on my main phone (connected via bluetooth) from this one. As for phone calls, Tablet Talk gives a nice notification about who is calling, with the contact's photo and name synced from your phone book.

ISSUE: Tablet talk is meant for tablets. So when used in landscape mode, the answer/reject/speaker button goes below the screen. So I created a tasker profile, which says when I get a call notification on tablet talk, disable screen rotation temporarily. Does the trick ;)

Another issue is that the calls are attended from your phone. i.e. call audio comes from your phone. Simple solution, also connected the phone with my car's bluetooth (another hack made from a broken 20$ Sony MW600 bluetooth headset I found on eBay). So I can answer the call from OPO fixed in car, and talk via car bluetooth, and the phone always stays inside.

b) Music & audio

I have my full music collection on my main phone. I don't want to sync and have duplicates. Thank's to a discovery by [MENTION=3031979]darktranquility18[/MENTION], I realized that the OPO can be used as a media sync when using bluetooth. i.e. It acts as a bluetooth speaker for my main phone. Now, the issue I ran into was that I couldn't change tracks or volume using it directly. So I had to use another software: Tablet Remote. Works like a charm :D
​

That's all I have for now. Let me know if you can think of any suggestions, additions or ideas. Open to many more tweaks and hacks. After all, the phone says: Never Settle :D
