Integrating BleuIO with Adafruit Feather RP2040 for Seamless BLE Applications Part 2

• Search for ClosedCube OPT3002, and install the ClosedCube OPT3002 library

• And a SCL clock wire, and and a SDA data wire.

• (Optional) Change the frequency the sensors are read and advertising data updated, in the code
  

// How often we read the sensors and update the advertings message

(in seconds)

#define READ_UPDATE_FREQUENCY   5

Scanning the results

To see the results you can use any BLE scanner app.

Here we use nRF Connect:

The data in the red box is our sensor values:

0x006203EB001700170041

When we parse the hex into decimal values we get:

Light: 0x0062 = 98 uW/cm2


Pressure: 0x03EB = 1003 hPa


Temperature: 0x0017 = 23 Celcius


Humidity: 0x0017 = 23 %Rh


Gas Resistance: 0x0041 = 65 KOhms
