I am using the TF-Lunar Lidar module with an Arduino Uno board and it works quite well.
The default Baud rate for the serial data is 115200 bps which works ok for the UART port on the Uno board, but is too fast for a software serial port.
So I would like to change the default serial Baud rate for the device.
The Product Manual is here: (https://files.seeedstudio.com/wiki/Grove-TF_Mini_LiDAR/res/DE-LiDAR%20TFmini%20Datasheet-V1.7-EN.pdf)
It lists configuration commands on Page 15 in Table 9, and I have been able to use most of the commands OK, but I don’t understand the command for setting the Baud Rate.
The command is shown as: Baud rate 5A 08 06 H1 H2 H3 H4 SU
What I don’t understand is what is required for the H1 H2 H3 H4 fields which are obviously used to specify the Baud rate.
Any help greatly appreciated.
