Unkown packet type: 28

[Richard-Haes-Ellis]

I recently got a hold of one Radar_MB_1R2T_V1.5.8 lidar from Aliexpress and I'm getting "Unknown packet type: 28". I haven't looked at the datasheet yet as I just wanted to test out the lidar before. What does this error mean?

Im actually getting a mis of 28 and 93 error codes if that helps. I've also added a logic analyzer capture, perhaps you can compare it to your lidar and see if its radically different.

I used the Saele Logic Analizer (https://www.saleae.com/)

I don't have a proper datasheet, so this driver is mainly a product of reverse engineering and a previously created ROS1 driver. If you could find out what that packages mean, you could add these definitions to the driver via a PR. My lidar does not produce this packets or at least it did not while I was testing it.
