A method of wirelessly exchanging glucose information between a first communication device associated with a continuous glucose sensor and a second communication device (14, 16, 18, 20) associated with a glucose information display device, the method comprising: receiving, using a user interface of the second communication device (14, 16, 18, 20), user input comprising an identifier associated with the first communication device; generating, using the second communication device (14, 16, 18, 20), both a first device ID and a sensor security code, based on said identifier; transmitting a first beacon using the first communication device, the first beacon comprising a second device ID and a challenge value; receiving the first beacon using the second communication device (14, 16, 18, 20); determining, using the second communication device (14, 16, 18, 20), if the second device ID transmitted by the first communication device matches the first device ID stored at the second communication device (14, 16, 18, 20); and executing an authentication protocol, using the second communication device (14, 16, 18, 20), if the second communication device (14, 16, 18, 20) determines that the first device ID matches the second device ID, wherein executing the authentication protocol comprises: generating using the second communication device (14, 16, 18, 20), a first authentication key based on the challenge value provided by the first communication device and the sensor security code, wherein generating the first authentication key comprises applying a hash algorithm using the challenge value and the sensor security code; transmitting, using the second communication device (14, 16, 18, 20), the first authentication key and a request for glucose information; receiving, using the first communication device, the first authentication key; generating, using the first communication device, a second authentication key based on the challenge value; and determining, using the first communication device, if the first authentication key matches the second authentication key; and wherein the method further comprises transmitting the requested glucose information using the first communication device if the first authentication key matches the second authentication key. receiving, using a user interface of the second communication device (14, 16, 18, 20), user input comprising an identifier associated with the first communication device;
