9.1.20.6 Smart One Sensor Service Settings

Smart One Sensor Service is a BLE service the ST150M offers where up to 10 sensor nodes may advertise data to be sent
over-the-air when data is available and needs to send. The ST150M will switch from peripheral mode to central mode at the
Sensor Service Scan Interval below, and look for any advertising sensor nodes.
Up to 10 sensor nodes can work in conjunction with a single ST150M.
When a sensor advertisement is discovered, the sensor's data is captured and sent as a Type 59 or Type 63 Sensor OTA
Message (See Messages Section), and the sensor becomes whitelisted for a minimum of several seconds.
ECDSA is used in combination with a configurable AES public key to provide authentication of messages. Additionally, the
device's ESN or UID can be used to authenticate sensor nodes meant only for the intended ST150M.
