Pixhwak LED

#1

Hi
I have recently purchased one of the pi drones, I was trying to connect my TF-Lunar sensor. suddenly pixhwak stopped working and the B/E LED started blinking red (yellow). I cannot connect to the mission planner either with USB or Telem. Please help me. Is there any way to factory reset Pixhwak?

This is an old video, but I think it still applies.

Of course you don’t want to repeat the problem, so what steps did you take to install the lidar?

Here are some references I found:

thanks for your reply!
I have connected like the photo(to Serial4/5) I attached. I set all the parameters in MP. The Lidar doesn’t work.

Do you have the instruction manual?

Using I2C is an option.
