Welcome everyone! The problem is that I upgraded Upair px4 v1.2 to qgroundcontrol 3.5.6. I have not calibrated the level now. What firmware do you need or custom firmware? Thank you for your answers in advance.
What’s Upair? I don’t know what that is.
Upair one plus drone
The original UpAir One used a customised ArduPilot fork. The One Plus shifted from the 8 bit AVR board to a 32 bit STM32F4 PX4 variant. I never got hold of a firmware to see what it was based on: but I’d suggest it’s a safe bet that whether the firmware is PX4 or ArduPilot based, it won’t be a mainline release, so probably better to stick with what it shipped with.
Hi there…did you ever find out what firmware to use to update your upair?
