# ESP-DMX-WiFi
Art-Net to DMX gateway. It supports RDM and sACN (E1.31) too.
Strongly based on amazing [LXDMXWiFi_Library](https://github.com/claudeheintz/LXDMXWiFi_Library) example [ESP-DMX](https://github.com/claudeheintz/LXDMXWiFi_Library/tree/master/examples/ESP-DMX).
Configuration utility for macOS and Windows is [here](https://github.com/claudeheintz/LXDMXWiFi_Library/tree/master/examples/configuration%20utility)
The biggest change from source project is when connection to Station fail or timeout happens, it starts with default configuration (AP mode). There is no need to have a startup button.
```
uint8_t DMXwifiConfig::setupWiFi(IndicateActivityCallback indicateConnecting) {
... omissis ...
unsigned long start = millis();
while ((WiFi.status() != WL_CONNECTED) && ((millis() - start) < 15000)) {
delay(100);
indicateConnecting();
}
if (WiFi.status() != WL_CONNECTED) { // Connection to Station failed, start with default configuration (AP mode)
initConfig(); // initialize but do not store in EEPROM
rv = LX_AP_MODE;
WiFi.mode(WIFI_AP);
WiFi.softAP(SSID());
WiFi.softAPConfig(apIPAddress(), apGateway(), apSubnet());
}
... omissis ...
}
```
