Method for transmitting data in a blood glucose system and corresponding blood glucose system
First Claim
1. A method for wireless transmission of data between components of a blood glucose system including a master controller having a receiver and a transmitter and a slave device having a receiver and a transmitter, the method comprises the steps of:
- setting a sniff interval for the slave device to a first sniff interval;
determining whether a preamble data transmission is received within a first interval;
in the event the determining step is true, evaluating whether a remainder of the data frame is a communication initiation data frame and deciding whether an address portion of the data frame includes an address of the slave device;
in the event the evaluating step or the determining step is false, deactivating the receiver of the slave; and
in the event the deciding step is true, deactivating the receiver of the slave device and switching the slave device to a communication mode such that the transmitter of the slave device is activated to transmit a response to the master controller and then the receiver of the slave device is again activated to wait for further data frames from the master controller.

Abstract
The present invention relates to a method for wireless transmission of data between components of a blood glucose system (1, I1) including a master controller (2, 2′) having a receiver (10) and a transmitter (9), and at least one slave device (3) having a receiver (19) and a transmitter (18). The slave device (3) is normally operated in a power saving mode and its receiver (19) is only activated intermittently at a receiver activation frequency for a predetermined listening period. The controller (2, 21) transmits a communication initiation data frame to the slave device (3) via a preamble signal transmitted for a preamble period. Upon receipt of the communication initiation data frame, the slave device (3) is switched to a communication mode in which it transmits a response to the controller (2, 21), and the slave device (3) is switched from the communication mode to the power saving mode.
