1. A sensing device comprising:
an analyte sensor;
a memory;
a processor; and
a transceiver comprising:
a first radio unit configured for bidirectional communication with an external device using a first radio communication protocol, wherein the bidirectional communication comprises receiving configuration data from the external device; and
a second radio unit configured by the configuration data for unidirectional communication with the external device using a second radio communication protocol different from the first radio communication protocol, wherein the unidirectional communication comprises the second radio unit transmitting a second radio signal to the external device, wherein the second radio signal communicates data based on a plurality of measurements obtained by the analyte sensor; and
wherein the first radio communication protocol has a shorter range than the second radio communication protocol.
