If a sensor has stopped transmitting it may be due to the reception or antenna connection. Please use the following steps to troubleshoot.

1. Confirm that the antenna and cable isn’t damaged - inspect the length of the cable for any signs of rodent damage
   
2. Use the BLE Scanner under 'More' > 'Sensor Tools' > 'BLE Scanner' within the CropX App to see if the sensor is powered. The sensor should be detected by your mobile device and seen in the list.
   
3. If the BLE Scanner does not find the sensor and the sensor did not beep upon battery insert. Remove the foam pad in the bottom of the battery compartment if applicable. Then reinsert the charged battery and rescan with the BLE scanner.
   
   When the V4 sensor is not powered, then removing the pad can help.
   
   
4. Loosen and re-tighten Antenna cable and antenna connections making sure the cap is seated fully around the antenna connection in order to thread the connection completely 
5. Ensure the antenna is raised as high as possible
   
6. Run Diagnostics to trigger a new measurement and transmission test
   
7. If this fails then, perform these steps in order
   
1. Download data with your mobile device via Bluetooth if applicable - under sensor actions > 'Download Data'
   
2. Reset
   
3. Restore Factory (under 'More' > 'Sensor Tools' > 'Restore Factory')
   
4. Change Network (The sensor will search test its modem by searching for all available networks). IF this succeeds and displays a list of networks, choose the most appropriate network and save. IF this fails replace the sensor and contact CropX support. 
   
5. Run Diagnostics
8. You will receive a notification of sensor measurement success or failure
   
9. Contact CropX support if the failure continues at 650-265-0208
