Sensor startup
1.
When the sensor starts up, it loads
configuration from the internal memory and
merges it with user configuration.
2.
When the configuration is done, the sensor
writes the new configuration to the NFC chip.
The sensor always writes new configurations
to the NFC chip when something changes in
the sensor or if NFC data is corrupted by an
NFC writer or phone. The sensor always writes
the new configuration to NFC chip at startup.
3.
When the configuration is done, the sensor
tries to join the network if OTAA (Over the Air
Activation) is enabled.
4.
The sensor LED flashes orange when it tries to
join a network. It will try to join every 10
seconds initially. This interval will increase to
save battery, at most up to one time per hour.
5.
After successful connection to a network, the
sensor sends a settings packet and enters
sampling mode.
