Data transfer between electronic devices
First Claim
1. A method for communicating between electronic devices, comprising:
- in a transmitting electronic device,transmitting a first data channel protocol data unit (PDU) to a receiving electronic device using a short-range wireless communication interface in a sending window for the transmitting electronic device during a regular event during a connection interval, wherein the first data channel PDU comprises a payload with data D, and wherein the transmitting the first data channel PDU during the regular event comprises using a first frequency to transmit the first data channel PDU; and
transmitting a second data channel PDU to the receiving electronic device using the short-range wireless communication interface in a sending window for the transmitting electronic device during a retransmission event during the connection interval, wherein the second data channel PDU comprises a payload with the data D, and wherein the transmitting the second data channel PDU during the retransmission event comprises using a second frequency different from the first frequency to transmit the second data channel PDU and transmitting the second data channel PDU independent from whether the receiving electronic device listens for the second data channel PDU.

Abstract
During operation in the described embodiments, a transmitting electronic device transmits a first data channel protocol data unit (PDU) with a payload containing data D to a receiving electronic device using a Bluetooth Low Energy (BTLE) interface in a sending window for the transmitting electronic device during a regular event, wherein transmitting the first data channel PDU during the regular event comprises using a first frequency to transmit the first data channel PDU. The transmitting electronic device then transmits a second data channel PDU with a payload containing the same data D to the receiving electronic device using the BTLE interface in a sending window for the transmitting electronic device during a corresponding retransmission event, wherein transmitting the second data channel PDU during the retransmission event comprises using a second frequency to transmit the second data channel PDU.
