Initialization (Selecting UART Pins and Baudrate)

Initialize the ESP8266 module (Tx = P16, Rx = P15, Baudrate = 115200).

esp8266.init(SerialPin.P16, SerialPin.P15, BaudRate.BaudRate115200)

Show happy face if successful.
Show sad face if failed.

if (esp8266.isESP8266Initialized()) {
    basic.showIcon(IconNames.Happy)
} else {
    basic.showIcon(IconNames.Sad)
}

WiFi

Connect to WiFi router.

esp8266.connectWiFi("my_ssid", "my_password")

Show happy face if connected successfully.
Show sad face if failed.

if (esp8266.isWifiConnected()) {
    basic.showIcon(IconNames.Happy)
} else {
    basic.showIcon(IconNames.Sad)
}

Thingspeak

Upload data to Thingspeak (Data can only be uploaded every 15 seconds).

esp8266.uploadThingspeak("my_write_api_key", 0, 1, 2, 3, 4, 5, 6, 7)

Show happy face if data is uploaded successfully.
Show sad face if failed.

if (esp8266.isThingspeakUploaded()) {
    basic.showIcon(IconNames.Happy)
} else {
    basic.showIcon(IconNames.Sad)
}

Blynk

Read from Blynk.

let value = esp8266.readBlynk("my_blynk_token", "V0")

Write to Blynk.

esp8266.writeBlynk("my_blynk_token", "V1", "100")

Show happy face if Blynk was read/written successfully.
Show sad face if failed.

if (esp8266.isBlynkUpdated()) {
    basic.showIcon(IconNames.Happy)
} else {
    basic.showIcon(IconNames.Sad)
}

Internet Time

Initialize internet time to timezone +8.
Show sad face if failed.

esp8266.initInternetTime(8)
if (!(esp8266.isInternetTimeInitialized())) {
    basic.showIcon(IconNames.Sad)
}

Update the internet time and show the time.
Show sad face if failed.

esp8266.updateInternetTime()
if (!(esp8266.isInternetTimeUpdated())) {
    basic.showIcon(IconNames.Sad)
} else {
    basic.showString(esp8266.getHour() + ":" + esp8266.getMinute() + ":" + esp8266.getSecond())
}
