I investigated USB serial adaptors to the Parrot. The FTDI driver is in the Parrot Android, but there are some problems with loading it (you can hack it from the adb shell, or from an App with root access). Parrot themselves say it is not yet supported, but planned for future.
I investigated bluetooth. Prior to the latest firmware it didn't work at all. With the latest 2.1.1 firmware I have had more success. I managed to get bluetooth to my Pebble smartwatch working (which means I can control Parrot volume from my wrist), but so far I haven't managed to get bluetooth SPP working. It should work, so maybe just me,
From the OVMS hardware point of view, things are not so easy. The PIC18F is very limited and it is hard to get extra connections. It should be possible to disconnect the connection to the modem and instead go to a bluetooth module on that single ASYNC port (both 5v and 3.3v lines are available on the OVMS v2 board). I have heard, but not tried, that it might be possible to get a software async working on one of the free I/O pins - low baud rate with no flow control.
I am working on more sophisticated hardware with 6 ASYNC ports and 2 CAN buses! But, the bluetooth situation is a mess at the moment (Android supports bluetooth 2.2 but not BLE 4.0, and iPhone supports BLE 4.0 but not bluetooth 2.2 - good grief).

Hi all,

is it possible to use a serial to bluetooth dongle on the DIAG port of the module
to get data via bluetooth, requesting data with "MSG commands"? What I want
to do is to use OVMS like a bridge between my car and my parrot device (Android device)
in order to visualize the data I get to the screen. I want to avoid the SIM card and to get
data from the server.

Best regards,
Giannis
