I have an original 3dr pixhawk (not v2.1) and I am running rover (latest firmware) I am attempting to run the Here+ rtk system but am having some issues
first it does connect and acquire satellites Ive seen as many as 17. Also I am able to set the ground station location with mission planner.
But. The arming switch does not work and the Compass does not work mission planner does not detect a 2nd compass. Rotating the Here+ rover side puck does not show a compass change. I have both compass 1 and 2 selected in mission planner but only the internal pixhawk compass is recognized.
Because I am using the older pixhawk I had to switch to df13 connectors. I followed the pinout as shown in this link
So I have 3 df13 ends coming off the cable one to switch, one to i2c and one to GPS.
Why would the compass not be detected?
Why does the arm switch not function?
Can you confirm the wiring diagram?
