Data transmission method and device for robot using buffer

A data transmission device for robot, comprising:

• a transmitter configured to transmit an attribute reporting request to at least one node via an attribute request frame, wherein the attribute request frame is an extended data frame, and the attribute reporting request carries a length of a buffer configured to store attribute data, and the attribute data is in form of block data;
• a receiver configured to:
• receive a first attribute reporting response transmitted from the node, update the length of the buffer according to the first attribute reporting response, wherein the node determines whether a length of attribute data to be reported is greater than the length of the buffer, transmits the first attribute reporting response to the data transmission device in response to the length of the attribute data to be reported being greater than the length of the buffer, and the first attribute reporting response carries the length of the attribute data to be reported;
• receive the attribute data reported from the node wherein the node transmits the attribute data to the data transmission device in response to the length of the attribute data to be reported being not greater than the length of the buffer.

A data transmission device for robot, comprising:

• a processor;
• a receiver configured to receive an attribute reporting request from a main controller, wherein the attribute reporting request is transmitted via an attribute request frame, the attribute request frame is an extended data frame, and the attribute reporting request carries a length of a buffer configured to store attribute data;
• a transmitter configured to:
• transmit a first attribute reporting response to the main controller, in response to the processor the processor determining that a length of at least one attribute data to be reported is greater than the length of the buffer, wherein the first attribute reporting response carries the length of the attribute data to be reported;
• transmit the attribute data to the main controller via at least one block data, in response to the processor determining that the length of the attribute data to be reported is less than or equals to the length of the buffer.
