The RS1xx offers three packet format options:
▪
Laird
▪
Cayenne
▪
Laird 2
Prior to version 4.0, only the Laird option was available. If using the Laird packet format, the sensor must receive a network
time packet (in Laird binary format) before data is stored in memory for future transmission.
Data logging is not available with the Cayenne packet format, so network time is not required for this packet format. Refer to
the
Network Time section for more information.
The Laird 2 format was introduced in firmware version 5.4. The data format is the same as that of the Laird packet format, and
a time packet is also required from the network.
It differs from the Laird packet format in that it can be configured for unconfirmed packet transmission to the network, and
defaults to this behavior. Furthermore, a sensor data packet is sent immediately upon successfully joining the network such
that sensor data is immediately available to the server. Selection of the Laird 2 packet format can be observed physically in
that the green product LED is held on for 3s upon successfully joining the network.
The packet format can be configured on the Mobile App through the LoRa Radio Settings and Info option.
