Ruuvi sensor (bought Dec. 2023) stays with solid red LED on. Can´t connect to the sensor with the Ruuvi App anymore (neither with BLE nor with NFC).
Detectable and connectable via nRF Connect App. Once connected to the nRF App LED turns solid green. Firmware update possible as well. Once disconnected from nRF App LED turns solid RED again. Battery change didn´t help.
Any help appreciated.
Hi,
Please send image of the circuit board here and let’s see how it looks.

Hi @myxos ,
It looks like there is some dirt at the base of the button on the board. You could try to clean this with Q-tip and some alcohol. If this doesn’t solve the problem for you, please write to our email support@ruuvi.com.
Solved. 
Thanks
