ENES100 Arduino Library v6.2.4

One ENES100 library for the Arduino Uno and Arduino UNO R4 WiFi.

Board behavior

• Arduino Uno: uses the external ENES100 WiFi module over SoftwareSerial. The WiFi-module firmware must be compatible with the current ENES100 serial protocol.
• Arduino UNO R4 WiFi: uses the board's onboard WiFi and only the R4 registration data.
• Other boards intentionally fail at compile time.

begin()

Arduino Uno with external WiFi module:

Enes100.begin("Team Name", MATERIAL, 205, 1116, 3, 2);

UNO R4 WiFi:

Enes100.begin("Team Name", MATERIAL, 205, 1116);

The examples include a commented RX/TX form for classic Uno users. AdvancedPosition is explicitly UNO R4 WiFi-only because it uses the onboard 12x8 LED matrix.

Debug states (classic Uno + WiFi module)

• 1: connected
• 0: module is responding but WiFi/WebSocket connection is still in progress
• 255: no valid state response was received; this can occur briefly while the module boots

lastDisconnectReason is historical. If wifiConnected = true, a previous disconnect reason does not describe the current connection.

Example initialization

The examples intentionally avoid preprocessor #if blocks. The simple form is used directly:

Enes100.begin("Team Name", MATERIAL, 205, 1116);

On an Arduino Uno, this uses the standard external WiFi-module pins (module TX = 3, module RX = 2). If different pins are needed, the examples show the explicit form immediately below as a comment:

// If using an Arduino Uno with an external WiFi module, you can use this instead
// to explicitly assign the WiFi module TX and RX pins:
// Enes100.begin("Team Name", MATERIAL, 205, 1116, 3, 2);

The four-argument form remains the normal form for the Arduino UNO R4 WiFi.
