Omnipod® 5:
Dexcom G6 Transmitter issues

What do I do if I’m having issues with my
Omnipod 5 App connecting to my Transmitter?

Learn how to resolve communication issues between the Omnipod 5 App and your Dexcom G6 Transmitter.

Why does this happen?

Communication issues may occur after activating a new Pod, after switching to a new Dexcom G6 Transmitter or Sensor, or during normal system operation. This could be due to reasons such as Pod and Sensor placement, use of the Dexcom receiver, or incorrect Serial Number entered in the App. You may see the following messages or alerts in the App: 


Transmitter Not Found

If a Pod is unable to connect to the Transmitter within 20 minutes of activation, you will see “Transmitter Not Found”. 


Omnipod 5 Sensor Info

Within the Insulin tab, the Sensor Info display will reflect “Searching…” when the most recent glucose value is not received in a 5-minute window; this message often resolves itself.   

If the issue does not resolve on its own, continue to the troubleshooting steps below. 


Omnipod 5 Missing Sensor Values alert

A “Missing Sensor Values” Alert will occur when the Pod has not received any glucose values for more than one hour. This only happens in Automated Mode and may be seen when your sensor is in the 2-hour warmup period. 

What should you do?

  • Verify that your Dexcom G6 receiver is powered completely off as it cannot be used as part of the Omnipod 5 System. To use Automated Mode, you must use the Dexcom G6 mobile app on a compatible smartphone 
  • Open your Dexcom G6 app and ensure Sensor readings are present. If you do not have any Sensor readings or Dexcom-related issues are present, and it is outside of Sensor warmup, contact Dexcom for assistance 
  • Verify that your Transmitter Serial Number (SN) is entered into the Omnipod 5 App each time you change your Transmitter. Refer to the section titled Where to locate the Transmitter Serial Number (SN) for guidance on locating your Transmitter SN
  • Ensure that the SN in your Omnipod 5 App matches the SN in your Dexcom G6 app
  • Do not have any other Pods nearby that you may have tried to use or used. This will ensure other Pods are not in Bluetooth communication range of the Transmitter (approximately 30 feet or 9 meters)
  • Verify that your Pod and Transmitter are in direct line of sight. They should be worn on the same side of the body in a way that they can “see” one another without your body blocking communication. Refer to Dexcom G6 Sensor Placement in the Omnipod 5 User Guide
  • Toggle Bluetooth on and off, if using a compatible smartphone, and remove other devices that may be connected via Bluetooth
  • Wait up to 20 minutes after Pod activation for the values from your Sensor to appear in your Omnipod 5 App

What if my Pod and Transmitter still won’t connect?

Continue troubleshooting by removing and reentering the Transmitter Serial Number (SN) into your Omnipod 5 App following the steps below. You must be in Manual Mode to manage your Transmitter SN. Refer to Switching from Automated Mode to Manual Mode in the Omnipod 5 User Guide.
