# Parameter Setting
The following parameters must match on the sender and receiver.   

## Payload size & channel
```
	uint8_t payload = 32;
	uint8_t channel = CONFIG_RADIO_CHANNEL;
```

## Sender side
```
    // Set destination address using 5 characters
    esp_err_t ret = Nrf24_setTADDR(&dev, (uint8_t *)"FGHIJ");
```

## Receiver side
```
    // Set my own address using 5 characters
    esp_err_t ret = Nrf24_setRADDR(&dev, (uint8_t *)"FGHIJ");
```
