Using Zubax GNSS next to original external 3DR GPS


Can I use the Zubax gnss as the primary GPS but also have the old 3DR GPS online? The 3DR compass is attached to the Flytrex Live logging system and if possible, I’d like to keep using that too.
I’ve set BRD_CAN_ENABLE=2, GPS_TYPE=9, GPS_TYPE2=2 (uBlox) rebooted and calibrated the compasses. All three animations are moving but I’m not sure if its correct. Can’t get a gps fix. Also the log window keeps spamming “GPS 0: detected as PX4”

I’m setting it up on the new Pixhawk 2.1.

Hi, I would suggest you to take this question to the APM forums. As far as I know, APM doesn’t support multiple GNSS units, but I may be wrong.
