Lidar a3m1 error

Question

Hi,

I am using the RPLidar A3M1, but it is not functioning as expected. The system displays the following message:

Timeout set for 2000ms
RPLidar SDK: 2.0.0
Slamtec SDK: 2.1.0
Connected to COM13 @ 256000
Model: 43
Hardware Version: 113
Firmware Version: 7824
Serial No: 9B291C7164E72B13E0CF5E303CE92B13
Motor Ctrl Supported: False
Health: , Code 7209
System.ArgumentException: Parameter is not valid.

Could someone help me understand what might be causing this issue? I would appreciate any guidance on how to resolve it.

Many thanks!

Hmmm it looks like a screen render issue. Let me have it looked at.

Hi DJ looking forward to you

Something caught my eye actually... in the debug log it shows... Health: , Code 7209 There's no health value being returned - which isn't right. It also shows an error code of 7209. I'm not sure what that means. Does that lidar work with the slamtec robostudio?

it works well with Slamtec RoboStudio

Try with the latest update (https://synthiam.com/Support/Skills/Navigation/RPLidar?id=20980) and there should be better logging to understand what error you are receiving and why.

RPLidar A1 & RPLidar C1 works very good

The health is not returning a value. Check into your wiring or power to ensure it’s connected correctly. In addition, make sure it has the default values set. (Eg default settings) The log data is missing the health. I’m curious if you can show a screenshot of the health value from the robostudio. Any screenshots of log data from robo studio would be useful. This is using the Slamtec sdk so I’m having difficulty understanding why it wouldn’t work.  ps, if you post code, please use the code tags or press the code button in the editor. It makes it easier for me to read. I edited your message for it. Thanks

One more thing. The serial number and error code are different between your two log posts. So is the firmware versions. All the data is different im wondering if maybe the baudrate isn’t correct? Can you try a different baudrate? Because that would explain the weird values.
