Unsolicited uplink status commands
The sensor polls the server for configuration parameters the during the
Configure
state. This
is done by sending unsolicited uplink status report (0x20). This is gives quick feedback to the
installer that the installation has been successful and enables downlink configuration
commands to be sent. After approximately 2 minutes the device changes to
Operational
state.
Port:
Port 1
Payload 0x01 20 00
0x01: Data type
0x20: Status command
0x00: Normal startup
The expected behavior is 0x01 20 00. If not contact Talkpool support.
9.3
Periodic measurement reports
The sensors transmit periodic unsolicited measurement reports, either from a single
measurement or grouping several measurements to one transmission to conserve energy.
9.3.1
Periodic single measurement report
The default configuration is that temperature and humidity is measured and transmitted every
15
th
minute and transmitted. The data is compressed to conserve energy and minimizing
interference.
Port:
Port 2
Payload: Measurement value (see
chap 9.3.3)
Size: 3 Bytes
9.3.2
Periodic grouped measurement report
To optimize the time granularity or extend the battery life length, several measurements can
be grouped into a single transmission.
Port:
Port 3
Payload: Grouping header, Measurement value (T=0), Measurement value (T=-dT),
Measurement value (T=-2 x dT), ….
