UUID 0xFFFE – Device ID Number – Read/Write *
[0][1][2][3] Used for the Serial Number – Little Endian – Base64 expected – ‘A’ – ‘/’
– Demo limited to 0001 to 0009
– Power Cycle reset back to 0001
Notes
* The Device ID Number is four Base64 digits.
This is used in the UUID 0x2A00 – Device Name, UUID 0x2A25 – Serial Number, and is present in the Advertising Data in the Complete Local Name.
The demo firmware allows 0001 – 0009, enabling a small network of up to 9 devices for a Demo.
This enables identification of individual sensors in systems where devices are identified by a UUID (eg iOS phone / tablet) rather than the device address.
** The offsets are not used by the firmware. They provide a location for storing an offset.
Use an App such as nRF connect to view the GATT table.
Contact if you have any questions after using an App such as nRF.
The Sensor Sampling is synchronised to the advertising. When the accumulation of Advertising Periods exceeds the Sample Period, the sensors are sampled and the accumulation restarts from ZERO.
The setup is intended for where the advertising period is smaller than the sensor sampling period, for example a 2 second advertising period with a 6 second sensor sampling period, the sensors are samples every 3rd advertisment.
Similarly for the Green Led Flash timing.
Advertising Data
