How to launch two devices

[russellyq]

Hi, Thanks for your great work

I am trying to launch two devices at same time.

I am using "roslaunch livox_ros_driver livox_lidar.launch multi_topic:="1" bd_list:="XX&XX""

However, it can only launch one of these two devices.

To be clear, instead of using livox hub, are there any ways to launch two devices which are directly connected to laptop ?

[Livox-SDK]

"roslaunch livox_ros_driver livox_lidar.launch multi_topic:="1" bd_list:="XX&XX""

"multi_topic commandline parameter " is depreated,

add the broadcast code to livox_ros_driver/livox_ros_driver/config/livox_lidar_config.json file, for example:

{ "lidar_config": [ { "broadcast_code": "1PQDH5B00100041", "enable_connect": true, "return_mode": 0, "coordinate": 0, "imu_rate": 0, "extrinsic_parameter_source": 0, "enable_high_sensitivity": false }, { "broadcast_code": "0TFDG3U99101431", "enable_connect": true, "return_mode": 0, "coordinate": 0, "imu_rate": 0, "extrinsic_parameter_source": 0, "enable_high_sensitivity": false } ],

and then,use the following command : roslaunch livox_ros_driver livox_lidar.launch

Thanks for your reply.

I changed the config file as follows:

"lidar_config": [
    {
        "broadcast_code": "3WEDH7600103381",
        "enable_connect": true,
        "enable_fan": true,
        "return_mode": 0,
        "coordinate": 0,
        "imu_rate": 0,
        "extrinsic_parameter_source": 0,
        "enable_high_sensitivity": false
    },
    {
        "broadcast_code": "1HDDH1200100801",
        "enable_connect": true,
        "enable_fan": true,
        "return_mode": 0,
        "coordinate": 0,
        "imu_rate": 0,
        "extrinsic_parameter_source": 0,
        "enable_high_sensitivity": false
    }
],

However, it still can only launch one of these two lidars.

Is it possible because of Ethernet port ?

One lidar converter is connected to the network port on PC and one lidar cable is converted to usb 3.0 and conects to PC.

Hi, russellyq Both lidars must be connected to your PC in the same loacal erea network！ You can buy a network switch or network router.
