Ruuvi with Cerbo GX & v2.84 not working

I bought the Ruuvi tag recently. My Cerbo software was older than 2.80 so I upgraded (v2.84 at the time). The bluetooth sensors option showed up, but I never saw the sensors - even if they were located right next to the Cerbo. I'm also using the touchscreen.

Any suggestions?

Settings --> I/O

Ensure Bluetooth sensors is enabled

Then it should show the Ruuvis

May have to enable them individually on the I/O screen

I saw a note on one of the changelogs that an external USB-Bluetooth dongle is recommended when you want to connect to the Ruuvi sensors as the internal Bluetooth antenna isn't very powerful.

> Cerbo GX requires a Bluetooth USB adapter for Bluetooth
The Bluetooth Radio in the Cerbo GX is not reliable enough to work with the Ruuvi sensors. Therefore, when installing Ruuvi sensors, we recommend to install a Bluetooth USB adapter. List of tested USB Bluetooth adapters.

Indeed, the built in Bluetooth is not reliable for the Ruuvis.

Specifically the issue is internal temperature related, so some in cold conditions may see it working for a while.

Regardless, for all it is recommended to use one of the very affordable USB Bluetooth dongles listed in Paul’s answer.
