Mirf with multiple channels

Hi !

In my dream of understanding the NRF24L01+ modules and Mirf library I made this discovery.

Who can explain me this :

byte rx_addr[5] = {0xE7, 0xE7, 0xE7, 0xE7, 0xE7};
Mirf.setRADDR(rx_addr);

As seen here :
https://forum.sparkfun.com/viewtopic.php?f=13&t=28409

I tried :
String RADDR[] = {"btn00","btn00","btn00","btn00","btn00","btn00"};
Mirf.setRADDR((byte *)RADDR);

But it's not working.

Thanks for support

The nRF24L01 radio links use a 5 byte address. You are passing the setRADDR() the content of a String Object array. Nothing good will come of this.

Read the Data sheet for Nordic's nRF24L01. If you don't understand your tools there is no way you will construct a working mechanism.

ok,

I got the point.

At first I thought that setting address this way will setup the multiple channels, I was really wrong.

I set the address this way :

Mirf.setRADDR((byte *) "clt00");

I used this code to open all channels as by default there is only 2 open.

Mirf.configRegister(EN_RXADDR, 0x3F); //Activate all channels
