A computer implemented method for transmitting messages generated by a continuous glucose monitor (CGM), the method comprising: generating a first message at the CGM at a first time, the first message being related to blood glucose measuring； generating a second message at the CGM at a second time, the second time being after the first time, the second message being related to blood glucose measuring； determining an elapsed time since a transmitter of the CGM has transmitted data； determining whether the elapsed time is greater than a threshold； determining whether the second message is to be transmitted before the first message, in response to the elapsed time being greater than the threshold； and transmitting data corresponding with the second message before transmitting data corresponding with the first message to a diabetes management device, in response to determining that the second message is to be transmitted before the first message.
