NMEA USB out

[1959c172]

Would it be possible to have the autopilot NMEA data sent out via USB along with the Bluetooth out? I see we have adsb USB in already. I've been getting drop outs using Bluetooth and thought it would be more reliable via hardwired. Then we could use a USB to serial converter cable for output. Let me know, Thanks

I'd love this as well.

1) It reduces complexity of parts required. (BT dongle vs FTDI cable.) 2) It eliminates a source of RF noise. I doubt that BT is causing radio issues in the cockpit, but a BT dongle would ideally be mounted on the rear of the instrument panel, near the autopilot, and in that position it's significantly closer to sensitive analog circuitry.

In release 10.2.8.

@apps4av, neat and thanks a million!

Is there some documentation on what kind of hardware this was tested on, and what kind of cable we need?

Supported devices are here https://github.com/apps4av/avare/blob/master/app/src/main/res/xml/device_filter.xml

@apps4av Perfect.

I'm trying to give it a shot by looking in the IO menu, but I'm not seeing a menu entry which looks like it'd be the right one. All I see which seems relevant is Auto Pilot via Bluetooth.

You may install from GitHub releases. Or wait for update on the store. Google is taking very long these days to publish updates.

Oh, interesting. I had updated 2 days ago but missed that Google Play wasn't playing ball.

I installed the APK from the GitHub release and I can now see the Autopilot via USB option. Awesome! I'm waiting for the USB OTG module so I can plug my phone into an FTDI cable, but in the meantime I'm guessing that the connection string setting 230400,8,n,1 is:

• the baud rate,
• the data bits,
• the polarity, and
• the stop bits.

So for an AeroCruze 100 Trutrak autopilot, I would think I should set the string to 9600,8,n,1 to account for the required 9600 baud rate.
