Abstract
A method for data transmission includes: during Bluetooth communication, negotiating, by transmitting a sounding data packet at a data size which is a candidate value of a maximum transmission unit (MTU), with a second electronic device about an applied value of the MTU for the Bluetooth communication. Through the technical solution according to embodiments of the disclosure, MTU sounding is performed by sending a data packet during data transmission between Bluetooth devices. Through the MTU negotiation between the two parties of interaction, an appropriate and stable MTU value is finally obtained to serve as a standard parameter of the interaction.
