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 preamble period to a first preamble period;
transmitting a communication initiation data frame;
activating a receiver of the master controller for a first receiving period of time to receive signals from the slave device;
in the event no response has been received by the master controller during the first receiving period of time from the slave device then;
setting the preamble period to a second preamble period different from the first period,retransmitting the communication initiation data frame, andactivating the receiver of the master controller for the first receiving period of time to receive signals from the slave device;
in the event a response has been received by the master controller during the first receiving period of time thenpreparing further data frames to include the slave device address portion and command portion,setting a preamble period to a second preamble period,transmitting the further data frames, andactivating the receiver of the master controller for the first receiving period of time to receive signals from the slave device until a response is received by the master controller.

Abstract
A method for wireless transmission of data between 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), and to a corresponding blood glucose system (1, I1). The slave device (3) is normally operated in a power saving mode in which 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) by means of a signal comprising 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.

-
setting a preamble period to a first preamble period; transmitting a communication initiation data frame; activating a receiver of the master controller for a first receiving period of time to receive signals from the slave device; in the event no response has been received by the master controller during the first receiving period of time from the slave device then; setting the preamble period to a second preamble period different from the first period, retransmitting the communication initiation data frame, and activating the receiver of the master controller for the first receiving period of time to receive signals from the slave device; in the event a response has been received by the master controller during the first receiving period of time then preparing further data frames to include the slave device address portion and command portion, setting a preamble period to a second preamble period, transmitting the further data frames, and activating the receiver of the master controller for the first receiving period of time to receive signals from the slave device until a response is received by the master controller. - View Dependent Claims (4, 20)

2. 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; in the event the evaluating step or the determining step is false, deactivating the receiver of the slave or in the event the evaluating step is true, deciding whether an address portion of the data frame includes an address of the slave device; 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. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
