Peripheral Examples
Wi-Fi 6 (2.4 GHz + 5 GHz)
cpp
#include <WiFi.h>
void setup() {
Serial.begin(115200);
WiFi.begin("your-ssid", "your-password");
while (WiFi.status() != WL_CONNECTED) {
delay(500); Serial.print(".");
}
Serial.println("\nConnected: " + WiFi.localIP().toString());
Serial.printf("RSSI: %d dBm\n", WiFi.RSSI());
}
void loop() { delay(1000); }Bluetooth LE Beacon
cpp
#include <BLEDevice.h>
#include <BLEAdvertising.h>
void setup() {
Serial.begin(115200);
BLEDevice::init("T7-C5");
BLEAdvertising *adv = BLEDevice::getAdvertising();
adv->setScanResponse(false);
BLEDevice::startAdvertising();
Serial.println("BLE advertising started");
}
void loop() { delay(1000); }Notes
- Dual-band Wi-Fi 6: 2.4 GHz + 5 GHz (802.11ax) — first ESP32 chip to support both bands
- Protocols: Bluetooth 5 LE, Thread/Zigbee (IEEE 802.15.4)
- SDK requirement: Arduino ESP32 core v3.x+ and ESP-IDF v5.3+ are required
- Antenna: Onboard ceramic antenna
FAQ
Q: Board not listed in Arduino IDE? A: The ESP32-C5 requires Arduino ESP32 core v3.x or later. Update via Boards Manager.
Q: 5 GHz Wi-Fi not connecting? A: Verify your router supports 802.11ax (Wi-Fi 6) on 5 GHz and that you are using the correct SSID/password for the 5 GHz band.
