Frozen/Stuck Reading - CustomTypeOne

If your reading appears “stuck” or not updating, there are a few common causes.

Is the BG value shown in blue?

Blue indicates that SugarPixel is not receiving new readings from your data source. This commonly happens due to:

Sensor warmup, signal loss, or sensor error
The CGM phone having no internet connection
The CGM app not uploading
A temporary CGM server outage

If your Dexcom Follow app, Libre LinkUp app, Gluroo app, or Nightscout site is not showing current readings, SugarPixel will not update either. In these cases, you will need to wait for the upstream issue to resolve.

Does your follower app show current readings, but SugarPixel is delayed more than 15 minutes (and not blue)?

This usually indicates a WiFi network issue — most commonly mesh networks or WiFi extenders. If you use:

A mesh WiFi system (multiple small nodes around your home), or
WiFi extenders

These setups can prevent stable communication even if other devices appear to work normally. Please follow the Home WiFi Advanced / Troubleshooting guide and set up a 2.4GHz Guest Network, then connect SugarPixel to that network. This resolves the issue in most cases.
