EMDCB

EMDCB is a BLE-based human detection sensor and illuminance sensor.
It can be attached to ceilings, etc., to measure the amount of light in a room and the number of people entering and leaving the room.

isDevice(peripheral)

Determine if the scanned peripheral is an EMDCB with BLE.

// Javascript Example
await obniz.ble.initWait();
const EMDCB = Obniz.getPartsClass("EMDCB");
obniz.ble.scan.onfind = async (peripheral) => {
  if (EMDCB.isDevice(peripheral)) {
    console.log("device find");
    console.log(peripheral);
  }
};
await obniz.ble.scan.startWait();

getData()

Parses advertisement and retrieves data.
There are two types of advertisements, Sensor Data and Commissioning Data, which differ in the data they return.
(see data format)

// Javascript Example
await obniz.ble.initWait();
const EMDCB = Obniz.getPartsClass("EMDCB");
obniz.ble.scan.onfind = async (peripheral) => {
  if (EMDCB.isDevice(peripheral)) {
    const result = EMDCB.getData(peripheral);
    console.log(result)
  }
};
await obniz.ble.scan.startWait();

Data format

Sensor Data

{
  address: string;
  energy_level?: number; //電池残量(%)
  light_level_solar_cell?: number; //太陽電池の光量(lx)
  light_level_sensor?: number; //センサーの光量(lx)
  occupancy_status?: boolean; //人がいるかどうか
}

Commissioning Data

{
  address: string;
  commissioning_info?: number[]; //AES key & device address(22byte)
}
