Vibration sensor transmission count premature reset

Hardware
1

While troubleshooting our one and two channel vibration sensors there is a transmission_count reading. As I understand it this is supposed to reach a count of 254 before it resets and counts up again from 1 to 254.

The battery life on the sensor is not dropping below 3.28, the RSSI to the gateway is in an acceptable range of below -65dBm

What would cause it to reset premature of 254 besides physically resetting it or sending a command?

These are communicating using a 900mhz modem with Node-Red and the NCD-RED-WIRELESS library v1.6.21.

it sensor encounters error during any operation which it can not resolve it will trigger the WDT and that will reset the sensor and counter.

how frequently this is happening.

also setting network id will do it as well ( if you are setting it using node red)

OTF is on but network ID configuration is turned off. We have Set On Request Timeout on, Sampling Interval on, ODR on, and Dead Band in mg on. I attached a graph of the frequency.

when was the device first installed ?

possible 4 reason –

  1. if devices fails to send data 5 times in a row. i.e. – device sent the data packet and did not get ACK from the gateway 5 times in a row.
  2. receiving reboot command
  3. WDT reset
  4. if there is high magnet field around the sensor sometime and its tripping the reed switch

Thanks

June 21st was the adoption date.

You said " 1. if devices fails to send data 5 times in a row. i.e. – device sent the data packet and did not get ACK from the gateway 5 times in a row." does this apply if the sensor is set to broadcast?
