This is normal as new data comes in.

• Green = means it is new data
• Yellow = means data is 1 second old
• Orange = means data is 3 seconds old
• Red = means the connection with the probe has been lost

The further you are away from the probes and the more probes you are using, the slower the data will come in.

If a probe stays red or disappears entirely, see Bluetooth Troubleshooting: Android Permissions or Probes Not Showing Up. You can also hold measurements when you need to step out of Bluetooth range.
