Show OBD Status - Githubissues

What steps will reproduce the problem?
1. Start the application.
2. Watch the screen and try to tell if your phone can actually talk to the OBD 
reader.

What is the expected output? What do you see instead?
I would like to have a status message (e.g. in the main window) telling me 
whether an OBD reader has been found and the app can talk to it - in a way that 
is clear even to new users of the application.
Instead, I see a notification saying "ODB Connection has started". However, I 
get this on every app start, even when there is no OBD reader anywhere in 
sight, and the notification disappears as soon as I press "Start Live Data".

What version of the product are you using? On what operating system?
Currently using version 1.3, installed from f-droid.org. OS is CyanogenMod 
10.1.0 on a Nexus S, with a generic ELM327 reader, in a 2005 Audi A4.

Please provide any additional information below.
Testing a successful connection with the OBD reader could be done by sending a 
universally supported PID (e.g. Mode 01 PID 00 - list supported PIDs) and 
checking for a valid response. Connection status can be:
- Connected - if we got a valid response
- Invalid response - if we got a response but it doesn't look like a valid 
response to the PID we sent (e.g. for Mode 01 PID 00, if the response length is 
not equal to 4 bytes).
- OBD device not found - if no Bluetooth connection to the selected OBD device 
could be established
- No device selected - if no device has been selected in Settings
