No sending/receiving data on serial_driver_bridge #63

Hi, I wasn't able to neither send nor receive anything with launching the serial_driver_bridge_node.launch.py I'm trying to execute the launch file using the configurations of my device:

/**:
  ros__parameters:
    device_name: /dev/ttyUSB0
    baud_rate: 115200
    flow_control: none
    parity: none
    stop_bits: "1"

I'm using ros2 galactic in docker. I'm sending the following message to my device :

echo -ne '\x00\x00\x45\x44\x76\x00\x00\x36\xFF\x4F' > /dev/ttyUSB0

and I'm receiving back a message (using hexdump):

 0000000    0000    0000    0076    3600    4eff    0000    0000    0000
0000010    0000    0000    0000    0000    0000    0000    0000    0000

Is there any other special config to make it work? Thanks

I think the problem is #72 And I have created a PR to fix it. You can also clone my fork repo and build from source code to use serial_driver for now.

Thanks for the reply! I've decided to create one by hand and it has worked. I'll try your fork later.
