Hello,
I have bought a u-blox7 USB GPS module, have connected it to the Pi, it seems to work, but I've "re-discover" how awfully slow the fix of a GPS-only device is, so far as it's almost unusable in my experience (I'll have to keep my phone close to the dash so that it'll will provide good GPS data).
So I searched for A-GPS and luckily I found out that u-blox provides such a service. Check these links:

https://github.com/gokuhs/ublox-agps
I tried to make it work in our case but I experience the problem described in this issue (no answer unfortunately):
https://github.com/gokuhs/ublox-agps/issues/1
I don't think it's specific to the code, I believe something else also tries to use the serial port and we get this error. So, I wanted to ask the OAP developers, does OAP communicate in anyway with the /dev/tty/ACMO port or whatever equivalent the GPS module provides, in order to "publish" the sensor to the phone? If you do communicate with the device, could you possibly integrate the above A-GPS code so that we can insert the token in openauto_system.ini and make it work?
