Sensor cannot be found via bluetooth scan
One of our MetaWear C sensors was working perfectly for at least 5 weeks. However, a few days ago we cannot detect the sensor anymore. We used the sensor as a pendant and has a plastic case to keep out water. The sensor was not dropped nor smashed.
We tried to replace the battery as well as using different phones to scan the environment, the sensor didn't show up. It didn't show up when we scan the environment with the Nordic app. And the new battery showed fast voltage drop.
How can we deal with this sensor? We might need your help to identify the issue.
