Unbale to communicate with XL-320 with the Pixl board


I just bought a Pixl board for my raspberry but unfortunatelly none of my XL-320 are detected.
I’ve tryied different solution to solve this porblem but it has always been a failure.

I’v tryied the OS proposed by roboticIA and the one proposed by the Poppy git.
I’ve also tryied to change baudrate.

I hope you can help my to solve my problem.
