Systems and methods for display device and sensor electronics unit communication

A display device for communicating with sensor electronics of an analyte monitoring system, the sensor electronics processing sensor information and transmitting processed sensor information to the display device, the display device comprising:

• a display;
• a first communicator comprising a Near Field Communication (NFC) module configured to communicate with the sensor electronics via a first communication protocol using the NFC module;
• a second communicator comprising a Bluetooth module configured to communicate with the sensor electronics via a second communication protocol using the Bluetooth module;
• a graphical user interface configured to present first processed sensor information received from the sensor electronics on the display, wherein the graphical user interface is configured to receive a user selection of one or more commands for transmission to the sensor electronics unit using the first communication protocol;
• wherein the display device is configured to:
• (1) transmit at least one of the one or more commands to the sensor electronics via the first communication protocol (2) receive second processed sensor information from the sensor electronics using the first communication protocol as a response to the transmitted at least one of the one or more commands, and (3) automatically receive third processed sensor information from the sensor electronics using the second communication protocol.
