Hi all, I am now connecting PX4FLOW to my quad. I have followed the instructions and comments posted before, such as using an external rangefinder, extra power supply. However, I am still getting the bad optflow health issue in Mission Planner. The external rangefinder I am using is the TFmini plus, which gives correct readings. The FMU I am using is the Holybro Pixhawk 4 FMU v5.
I also tried another way, connecting the USB cable of the PX4FLOW in addition to the I2C. Then, I can get correct opt_m_x, opt_m_y, opt_qual readings. But if I only use I2C, or use an extra power supply connected to the VCC and GND of the I2C port, then the bad optflow health issue arises.
Could you please provide some suggestions for my case? Thank you!
