issue using espnow on my esp32 wroom and dht11 (AEGHB-358)

[Brunno93]

I've connected a dht11 do pin 14 and a had the readings, but when I simply add a esp_now.h line in the code it stopped reading the sensor values.

Can anyone help. Pls!

@Brunno93 Could you share your code on the get-started example

const unsigned long eventInterval = 1000; unsigned long previousTime = 0;

float Temp; float Hum;

define DHTPIN 14

define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

typedef struct message { float temperature; float humidity; };

struct message myMessage;

void onDataReceiver(const uint8_t mac, const uint8_t incomingData, int len) { Serial.println("Message received."); // We don't use mac to verify the sender // Let us transform the incomingData into our message structure memcpy(&myMessage, incomingData, sizeof(myMessage)); Serial.println("=== Data ==="); Serial.print("Mac address: "); for (int i = 0; i < 6; i++) { Serial.print("0x"); Serial.print(mac[i], HEX); Serial.print(":"); }

Serial.print("\n\nTemperature: "); Serial.println(myMessage.temperature); Serial.print("\nHumidity: "); Serial.println(myMessage.humidity); Serial.println(); }

void setup() { Serial.begin(115200); WiFi.mode(WIFI_STA);

// Get Mac Add Serial.print("Mac Address: "); Serial.print(WiFi.macAddress()); Serial.println("ESP32 ESP-Now Broadcast");

// Initializing the ESP-NOW if (esp_now_init() != 0) { Serial.println("Problem during ESP-NOW init"); return; } esp_now_register_recv_cb(onDataReceiver); }

void loop() {

Hum = dht.readHumidity(); Temp = dht.readTemperature();

unsigned long currentTime = millis(); if (currentTime - previousTime >= eventInterval) {

Serial.print(F("Humidity: ")); Serial.print(h); Serial.print(F("% Temperature: ")); Serial.print(t);

previousTime = currentTime;

} }

@Brunno93 There is some issues need check from the code:

1. Where call the loop function which read Humidity and Temperature from DHT11?
2. onDataReceiver function only receive both Humidity and Temperature from the other esp-now device, it didn't have read option.
3. Could you change the pin14 to another pin? eg: https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/api-reference/peripherals/gpio.html?highlight=gpio
4. Please add the code on my provide example links which i can quickly reproduce it.

Thanks for help I put the espnow.h at the top and review some lines of code about espasyncwerver.h
