Known Issues

• Tempo Environment Monitor device cannot be paired to a Windows machine. If the target platform of your application is 32-bit Windows or 64-bit Windows, it cannot be paired to the Tempo Environment Monitor.
• Tempo Environment Monitor device has a timeout period of 10 seconds after connecting to the application, and then it disconnects. The application can request data and receive the response data during that period. After that, the application needs to connect again.
