Missing documentation about low_cmd.head

[SmnGdn]

Hello,
I'm trying to control the robot using ROS, but when sending a message I don't find any documentation on what values can the low_cmd.head take. Any information on what is this field doing, and what values it can take?

Thank you

Hello, I am sorry that we do not support sending udp directly to the motor for the time being. It is recommended that you switch the unitreearm class to lowcmd to send control commands to the motor by using our SDK.

Just to clarify, I am using the SDK, and I am sending low_cmd messages.
For anyone having the same question, these are the values you should use:
lowCmd_message.head[0] = 0xFE;
lowCmd_message.head[1] = 0xEF;
low_cmd_ros.levelFlag = LOWLEVEL;

Hello,you can click the link below for reference. In line 20 of this code, udp.InitCmdData(cmd); This can automatically set the frame header.
