Connection problem with Raspberry pi4b and the LSS Adapter

Hello everyone, i could use some help with connecting a raspberry pi4b to the LSS Adapter. so i have them connected with a USB cable, i have the complete Robotic Arm also connected and powerd with the LSS power supply that came with the Arm kit. when i use the LSS Flowarm web interface everything works and moves as expected. However when i try to control with the raspberry pi nothing moves. the pi runs without error, the green power light is on the LSS Adapter and i get a red blink or two from the LSS Adapter when i send a python code to the Adapter. the code runs without error is VS code and also in Thonny in the raspi. if Anyone could possibly tell me what im doing wrong or had the same problem and can help ? I would be truly Greatful.

Best Regards Nick.

Hi Nick46

Welcome to the RobotShop / Lynxmotion Community…!!

To sum it up, you already tried our app (it’s not a web interface) with your robotic arm and it was working.
Then you connected the LSS-Adapter USB directly to the Raspberry Pi and send Serial commands without any good results.

The first thing I would look for is the Baud Rate at which you are sending your serial commands.
If that do not solve the issue, you might want to verify that you are actually sending a carriage return at the end of your command as well.

We have a Python LSS library here:

All the best,
