# ESP32 ESP-IDF and ESP8266 RTOS SDK component for ESP-NOW interface
## Tested on
1. ESP8266 RTOS_SDK v3.4
2. ESP32 ESP-IDF v5.2
## Features
1. The maximum size of transmitted data is up to 250 bytes.
2. Support of any data types.
3. All nodes are not visible to the network scanner.
4. Not required a pre-pairings for data transfer.
5. Broadcast or unicast data transmissions.
6. Possibility uses WiFi AP or STA modes at the same time with ESP-NOW.
## Attention
1. For correct operation in ESP-NOW + STA mode, your WiFi router must be set to the same channel as ESP-NOW.
2. All devices on the network must have the same WiFi channel.
## [Function description](http://zh-espnow.zh.com.ru)
## Using
In an existing project, run the following command to install the component:
```text
cd ../your_project/components
git clone https://github.com/aZholtikov/zh_espnow.git
```
In the application, add the component:
```c
#include "zh_espnow.h"
```
## Example
Sending and receiving messages:
```c
#include "nvs_flash.h"
#include "esp_netif.h"
#include "zh_espnow.h"
#ifdef CONFIG_IDF_TARGET_ESP8266
