Using near-field communication both for out-of-band pairing and physiological data transfer
A method for obtaining physiological data from a medical sensor device includes detecting a proximity of the medical sensor device by an electronic computing device. After the proximity is detected, a message is received from the medical sensor device. A determination is made as to whether the received message includes configuration information for a wireless communication link. When the received message includes the configuration information for the wireless communication link, the wireless communication link is used to receive physiological data from the medical sensor device and the received physiological data is processed at the electronic computing device. When the received message does not include configuration information for the wireless communication link, a determination is made as to whether the received message includes physiological data. When the received message includes the physiological data, the physiological data is processed at the electronic computing device.
