Configuration
The following fields in secrets.h have to be configured:
- CLIENT_MAC
- SERVER_MAC
- PMK
- LMK
You have to configure the real STA MAC address of both the client and server. It might be odd that the AP MAC of the receiver isn't used, but that's how ESP-NOW works. You can find the MAC address with the following code.
#include <esp_wifi.h>
void printMacAddress()
{
uint8_t mac[6];
esp_err_t ret = esp_wifi_get_mac(WIFI_IF_STA, mac);
if (ret == ESP_OK) {
Serial.printf("{ %#x, %#x, %#x, %#x, %#x, %#x }\n",
mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);
}
else {
Serial.println("Failed to read MAC address");
}
}PMK and LMK have to be 16 characters long and should be the same between the client and server.
