A flag value of 0x00 means no sensor data is included in that particular advertising packet. This could occur when:
Sensors are disabled in the device configuration
The device is sending only beacon identification data without sensor telemetry
The device is in a specific power-saving or initialization state
The fact that you occasionally see normal data (like 0x83 in your last log entry) suggests the sensor is functional but intermittently sending packets without sensor data. This may be normal behaviour depending on your configuration, but it’s worth investigating further. Please contact support via Partner Portal
There is no option to reset to the default configuration, just to save the configuration and to upload the configuration
