4.3 SENSOR BOARD GATT SERVICE
The data from the RN4870 peripheral IO are stored in the characteristics of a custom
GATT service accessed by the Sensor Board BLE Client App. To create the Sensor
Board GATT Service, enter the following commands while in Command mode:
1.
PS,AD11CF40063F11E5BE3E0002A5D5C51B
to create a 128-bit UUID to
identify the GATT Service.
2.
PC,BF3FBD80063F11E59E690002A5D5C501,10,02
to declare a two-byte
characteristic with notify property enabled. This characteristic stores the value of
the ADC channel used for light sensor.
3.
PC,BF3FBD80063F11E59E690002A5D5C502,10,02
to declare a two-byte
characteristic with notify property enabled. This characteristic stores the value of
ADC channel used for potentiometer.
4.
PC,BF3FBD80063F11E59E690002A5D5C503,18,14
to declare a 20-byte
value used to manage both the Push button state (virtual LED in App) and the
LED blink rate on the Sensor board. Both notify and write properties are enabled
for this characteristic.
