Adapting Other Examples
Once you've got it connecting to the Internet you can check out the other examples. The only change
you'll want to make is at the top of the sketches, add:
#define SPIWIFI SPI // The SPI port
#define SPIWIFI_SS 10 // Chip select pin
#define ESP32_RESETN 5 // Reset pin
#define SPIWIFI_ACK 7 // a.k.a BUSY or READY pin
#define ESP32_GPIO0 6
And then before you check the status() of the module, call the function WiFi.setPins(SPIWIFI_SS,
SPIWIFI_ACK, ESP32_RESETN, ESP32_GPIO0, &SPIWIFI); like so:
// check for the WiFi module:
WiFi.setPins(SPIWIFI_SS, SPIWIFI_ACK, ESP32_RESETN, ESP32_GPIO0, &SPIWIFI);
while (WiFi.status() == WL_NO_MODULE) {
Serial.println("Communication with WiFi module failed!");
// don't continue
delay(1000);
}
