Hello,
Using a Windows (10) PC, I can connect and program via USB or Bluetooth to my XRP without any problems.
As I need this PC for another purpose, I would like to use another PC; this one has Linux. Unfortunately, I cannot connect via USB or Bluetooth with this Linux PC with the same XRP (and USB cable).
XRP has MicroPython v1.23.0 on 2024-06-02; Raspberry Pi Pico W with RP2040
Linux is Ubuntu 24.04.1 LTS
with Google Chrome 132.0.6834.159 (downloaded/installed on 01/29/2025)
Using the same USB cable on the Linux PC, I get:
Board in FS mode (ttyACMo) - Paired
Connection FAILED. Check cable and try again.
I have tried other cables (that work on Windows).
If I press the Bootsel button on the Pico and connect the Linux PC and the XRP, the RPI-RP2 USB drive appears.
The Linux PC detects the Bluetooth from the XRP but cannot connect.
Are there drivers for Google Chrome (or this flavor of Ubuntu) that I need to install?
Any suggestions/help is appreciated.
I do not have a PC set up in this way. But, the main things to Google would be WebSerial and Ubuntu.
I’m having the same issue. Can’t connect with Linux. I’ve added a udev rule as suggested by the internet, but still can’t connect using Chrome on Linux MINT. Would be nice to get some help on this one: the location where we are using XRP is 100% Linux.
UDEV rule that is not working:
UBSYSTEM=="usb", ATTR{idVendor}=="2e8a", ATTR{idProduct}=="0005", MODE="0664", GROUP="plugdev"
lsusb:
...
Bus 001 Device 006: ID 2e8a:0005 MicroPython Board in FS mode
...
I have spent several hours researching, and trying different solutions. I am still unable to use my XRP with Bluetooth on Ubuntu.
Updated MicroPython,
made sure my {username} was part of group dialout,
removed brltty,
successfully paired the XRP with Bluetoothctl pair {device ID},
verified that I can connect to the XRP via USB (in Chrome).
I could not find WebSerial on my Ubuntu machine and installation instructions are unclear for XRP. How should it be installed?
Any insights/help is appreciated.
So that I don’t keep banging my head against an unbreakable wall, is there anyone who is using Linux (any flavor) with XRP and connecting successfully via Bluetooth (even USB)?
I am using Raspberry PI 5 desktop with Bookworm operating system. Chromium browser works connecting XRP robot via USB and Bluetooth after enabling experimental features.
