Solo with third parties gimbals

[denmol81]

Hello there I just did this!!! I put a tarot 2d gimbal in my Solo and is fully functional, the tilt, and I also can power the gopro through that light weight USB cable I did, which I connected to the gimbal output cables, I used the power lines 5V+ plus ground, I also connected Data+ and Data-, but I cannot control the camera through this, like record, change the settings, etc.
Are those two DATA lines for this??? Any Idea???
Please help me with this,...you can check the video of the gimbal working here

Straight from the 3DR solo developement guide https://dev.3dr.com/hardware-accessorybay.html

Pin Name Color Description
1 VCC Battery Red 12V to 16.8V. Max recommended current/power is ~3A/50W. Drawing additional current may damage the battery and increases the risk of accident.
2 VCC 5V Yellow 4.75V to 5.4V voltage pin for Camera (only). Current should be less than 1A.
3 GND (Gimbal) Black
4 GND (USB) Brown
5 Gimbal Rx White
6 Gimbal Tx Green
7 USB D+ Blue Positive differential data signal to iMX6 OTG USB port.
8 USB D- Violet Negative differential data signal to iMX6 OTG USB port.

The Gimbal TX and Gimbal RX lines send Mavlink data over a serial connection between the Pixhawk flight controller and the gimbal. This connection is used to both control the pitch, roll, and yaw of the gimbal motors as well as send commands over to the camera (start recording, stop recording, change modes, etc).

This is through the back-plane of the GoPro camera,

Good job, keep up the great work!

You could mount the camera upside down to get better access to the HDMI port.
