Hello Everyone,
I have mounted a FLIR Vue Pro R thermal camera core to my 3DR Solo for obtaining still thermal-IR images.  The Vue Pro has an Accessory Port cable that is pre-terminated to connect properly with the 3DR PixHawk TELEM 1 port (see attached illustration from Vue Pro user guide).  The Vue Pro can be configured to capture telemetry data provided by GPS, altimeter, accelerometers from the PixHawk. This data is saved as standard EXIF metadata in the still image files (TIFF). Does anyone have experience with the PixHawk on board the Solo with regards to a TELEM 1 port being available for connecting the Vue Pro’s Accessory Port cable to?
Warm regards,
- Craig Thompson

Hi Joel,

Well, I've connected my Vue Pro to the Solo, upgraded the firmware on the Pixhawk and setup the Mission Planner for the correct parameters on the SERIAL2_PROTOCOL.  I've got the radiometric temperature values on the JPEG images but I'm not sure if the location telemetry data has been encoded on the images.  What software are you using to check to see if your images have the temperature values and location data?

Thanks!

Yes, that all looks correct.

**BUT**

Do not do this, yet. If you change the SERIAL2_PROTOCOL parameter you will probably brick your Solo (ie it will never boot up properly).

When you look at your Solo app you will see that the firmware version is 2.4.2 (or something like that). But your Pixhawk has it's own firmware, and it will be running version 1.3.1 from July last year. For some unknown reason 1.3.1 doesn't allow mavlink via serial2, so you need to update the Pixhawk firmware to a newer version, like 1.5.2, before you change that parameter.

There's a very good post on 3drPilots about the process for upgrading to 1.5.2 here:

http://3drpilots.com/threads/autopilot-firmware-upgrade-from-1-3-1-...

If you do this, follow their instructions exactly.

And there's a very long post on the 3DR Solo Hacks facebook group with a lot of info about this particular problem (just search for SERIAL2_PROTOCOL).

I hope this helps, please let us know how you get on.

I get it too ! Thanks

BUT do not forget to also set the MAVLINK setting in the Flir with your smartphone. Settings menu -> ACCY. PORT -> Serial Protocol -> Mavlink.

Mr YangdaOnline Representative,

Is your gimbal able to write the telemetry data (latitude, longitude, altitude, etc.) from the Solo PixHawk2 autopilot to the JPG still images collected on the FLIR Vue Pro?  I would definitely be interested in purchasing your gimbal if that was indeed the case.

Warm regards,

Hi Craig,

Sorry the gimbal can not do that currently.

Best regards,

Gary Chen

Craig,

You were asking about software to read the geotags - you should just be able to do it in Windows Explorer. Right click on the image, select Properties, go to the Details tab, then scroll down to the GPS section.

Hi Gary,

Thanks so much for the reply.  Appreciate you answering me so quickly.

Warm regards,

- Craig

Hi Joel,

Thanks for the info on how to check for GeoTag data.  And thanks so much for your suggestion that you posted over at the 3DR Pilots forum about the Rx (green) and Tx (white) wiring.  You were right!!  They were in the opposite slots on the connector!  I just switched them and was able to get the telemetry data!  :-)   I appreciate all your assistance!

Warm regards,

- Craig

Awesome, glad I could help.

Out of interest which Pixhawk firmware version did you end up using?

Hi Joel,

I used PixHawk firmware 1.5.3

Hey Craig,

I've been working on this for the last few days and I have gotten stuck.  I believe I've followed everything done here, but the telemetry data is not being written to the .jpg files.  I used the same wires you had (Viresity) and the accessory board.  I have updated the firmware and changed the FLIR camera to 'Mavlink'.  The only thing I'm not sure about is the 7 pin Molex to 2 pin DuPont connector.  Not sure what to do with that.  If you're still around or if anyone has any suggestions, I'd be very grateful!

Matthew,

Have you checked that you've got the green wire going to Serial 2 RX, white wire to TX, and black to Ground? I think Craig mentioned that the white and green were reversed in the cable he bought.

The 2 pin connectors go to the Ch6 and Ch7 PWM inputs so that you can send trigger signals and change settings.

Joel

Joel,

I tried switching the RX and TX, but my GPS coordinates still all show up as 0,0,0.  Any thoughts?

Matthew
