Survey Single
Test connectivity with the gateway at different data rate and power combinations. Each survey whether it passed or failed saves survey results to a data file on the device but only successful surveys are transmitted to the gateway. See Survey Data File for data format.
- The device joins the network. The LED1 flashes and the device
displays Joining message. Once complete, the LED1 turns green and
the Join Success message appears. If Join fails, check: the network ID,
the network key, frequency sub band to make sure they match the gateway.
See Configuration Mode for details. - If the data file exists, choose either press SW2 to Erase or
SW1 to Append the current file. - Press SW2 to select the first survey or SW1 to cycle through the
data rate/power combinations to desired selection. - Then press SW2 to start selected survey.
- LED1 flashes and one of the following results
appears:- If a survey is successful, the device displays:
- Survey index: survey ID.
- TX data rate and power
- Up margin: upstream signal margin (dBm) above
the demodulation floor (level at which signal can no
longer be distinguished from noise). - Down RSSI and SNR: downstream signal strength
in dBm and signal-to-noise ratio. - GPS longitude(if available)
- GPS latitude(if available)
- GPS time and date(UTC format — if available)
- If the survey was successful and data packet transmission is
enabled, the device sends the following data:- TX power
- Number of gateways which received the link check
request - Up margin: the upstream margin above the
demodulation floor - Downstream RSSI and SNR
Note: If the data rate allows for enough payload, GPS
information will also be sent to the gateway. - If a survey is unsuccessful, the device displays:
- Survey index
- TX data rate and power
- Error message
- GPS longitude(if available)
- GPS latitude(if available)
- GPS time and date (UTC format — if available)
- If a survey is successful, the device displays:
- LED1 flashes and one of the following results
