CPT not connecting to Display and/or AppUpdated a month ago

"Not connecting" is a general symptom that can have a few different causes.

Thermometer on standby? 

Remove CPT from charger/booster.

It could mean the thermometer's battery is dead - that's usually because there's something interfering with charging.

Dirty contact?

Hey, it happens. If the charging contact (on the butt of the handle) is not making a good connection with the charger/Booster, the CPT won’t charge.

Scrub the contact with steel wool (it won’t hurt it) and see if you get a charge going. The charger light will turn from green to red (or amber) if the cleaning helped. After a full charge, try connecting.

For fully charged CPTs, an incomplete firmware update can prevent connection

Did you recently update the firmware?

Rarely, the thermometer may only partially update the firmware, leaving it uncommunicative. Although it may be fully charged, it will not communicate with either the Display or the App.

Very frustrating!

You can undo this but it takes time.

Leave the CPT outside of the charger/Booster for 48 hours. That will reset the firmware to factory settings so you can redo the firmware update.

Be sure to get the newest app version before applying firmware updates.

Don't try to do multiple firmware updates at the same time.
