Abstract: A data transmission method according to an I2C protocol and a transmission apparatus includes: a first transmission chip obtains I2C data from a first device, wherein the I2C data is data sent by the first device to a second device. The first transmission chip sends first feedback information to the first device, wherein the first feedback information is used to indicate whether the I2C data is successfully received. The first transmission chip forwards the I2C data to a second transmission chip corresponding to the second device. The first transmission chip receives second feedback information from the second transmission chip, and the second feedback information is used to indicate whether the I2C data is successfully received. The first transmission chip stores the second feedback information in a first storage space that is storage space of the first transmission chip.
