If you want to send data as ack payload you need to have different addresses for the different devices. you will then have to add the payload to the tx fifo for each device, make sure you watch the fifo status.

Hi run_ar,

Actually isn't working, even with two transceivers. I want to know how to broadcast the message, send it to all the transceivers. I was wondering that maybe exists a more practical way, because I'm also developing the library and need to know how to change the address of the modules to send it.

I read in some places to use the same address for all the transceivers to reach them all at the time by the tranceptor, when I tried this just one fo them could gets the message.

So, in the general way I'm looking for a way to send to all the transceivers the same message, is that possible? Or I do have to change the address every time I want to send it to a different module?

Hi,

I am not sure I understand what you are asking for. You say your configuration is already working? If you want to use the auto ack with payload feature you should look at chapter 7.4.1 Auto acknowledgement in the product specification. Remember that the ack payload has to be placed in the tx buffer before you receive the packet you want to ack.
