Configuration

In addition to selecting collected signals, you can configure the device after connecting.

Available settings

Setting	Command	Accepted values
LED brightness	set led_brght <value>	1–16
ECG sampling frequency	set ecg_fs <value>	250, 500, or 1000 Hz

Changing the ECG sampling frequency may break compatibility with official apps.

Sending a configuration command

Send the command through send(...) using the default processId of 0.

Python

# Set LED brightness to 10.
command = "set led_brght 10"

# To set the ECG sampling frequency to 500 Hz instead:
# command = "set ecg_fs 500"

await device.send(command)

Android

// Set LED brightness to 10.
val command = "set led_brght 10"

// To set the ECG sampling frequency to 500 Hz instead:
// val command = "set ecg_fs 500"

val payload = "$command\u0000".toByteArray(Charsets.UTF_8)
device.send(payload, processId = 0)

Apple Platforms

// Set LED brightness to 10.
let command = "set led_brght 10"

// To set the ECG sampling frequency to 500 Hz instead:
// let command = "set ecg_fs 500"

let payload: [UInt8] = Array("\(command)\0".utf8)
device.send(payload, processId: 0)

Flutter

import 'dart:convert';
import 'dart:typed_data';

// Set LED brightness to 10.
const command = 'set led_brght 10';

// To set the ECG sampling frequency to 500 Hz instead:
// const command = 'set ecg_fs 500';

final payload = Uint8List.fromList([...utf8.encode(command), 0]);
await device.send(payload, processId: 0);

Unity

using UnityEngine;

public class ConfigureAidlab : MonoBehaviour {
    private Aidlab.AidlabSDK sdk;

    void Start() {
        Aidlab.AidlabSDK.init();
        sdk = FindObjectOfType<Aidlab.AidlabSDK>();
        if (sdk == null) {
            return;
        }

        sdk.Connected += Configure;
        if (sdk.IsSdkInitialized) {
            Configure();
        }
    }

    void Configure() {
        // Set LED brightness to 10.
        sdk.SendCommand("set led_brght 10");

        // To set the ECG sampling frequency to 500 Hz instead:
        // sdk.SendCommand("set ecg_fs 500");
    }
}

Python strings and Unity's SendCommand(...) are null-terminated automatically. On Android, Apple platforms, and Flutter, encode the command as UTF-8 and append a null byte as shown above.
