Benewake TF02 pro rangefinder

I’m currently working on integrating benewake TF02 pro rangefinder with the pixhawk 6c configuring on missing planner with ardupilot.

I have plugged it into the telem 2 port using UART and configured that which is serial port 2 put that on a baud rate 115200 with the protocol rangefinder. Followed the ardupilot guide of which parameters to change and currently receiving power which is only 5Volts with the pixhawk.

the problem is that when checking the data in mission planner no data is being outputted from the lidar.

I’ve come across that it could be that it needs to be supplied with 12 volts instead of 5Volts to send off the data.

Is there anything else it could be why the data is not being outputted to mission planner from the Lidar.

The manufacture says this module has a wide input range from 5-12V, so it has also to work on 5V and I assume this is not the problem.
As I see on the manual the TF02 pro has a 4 pin connector while th pixhawk 6c has a 6 pin connector on Telem 2. How you connected the TF02 to the FC?
It must be:
FC 5V to TF02 5V
FC GND to TF02 GND
FC Telem2 RX to TF02 TX
FC Telem2 TX to TF02 RX
Did you configured the TF02 directly with a PC (USB to UART Adapter)?

The wiring met the requirements you outlined and missed the SDA and SLA Pins on telem 2 connector, and it was configured in mission planner using a usb connector to the pixhauk which the lidar was plugged into telem 2.

What do you mean with “it”. The parameters of the FC or directly the lidar itself.
To check if the lidar is working correct i recommend to directly connect the lidar to your pc using a USB FTDI Adaptor and a check with normal terminal software like TeraTerm

The LiDAR itself was configured with the parameters in mission planner for rangefinder1 (RNGFND1), to check if the LiDAR is working I need a TTL to usb connector, I was hoping to rule every other possible cause for the problem before doing this.

I think this is only setting parameters on the FC but is not talking with the LIDAR itself.
Maybe some setting is wrong, connection is not as good as it should be or the LIDAR itself is missconfigured or defective.
Last two points can be evaluated by connecting the LIDAR directly to a PC port
For the first point you have to show all your parameter settings.
Electrical connection can be checked with a multimeter

Ok thank you, appreciate the help :slight_smile:
