Radio Addresses in custom protocol

[lbe]

Good morning everyone,

I am writing a custom protocol using the RADIO module and I am having a hard time understanding the address organization.....

My protocol supports either unicast transmissions or broadcast transmissions, so I need each device to be able to receive on both addresses.

I read the (short) section 23.4 of the product specification and I had a look at the different sample codes available with the SDK, but it is 

still unclear to me how the addressing scheme works.

I would really appreciate if someone could point me to a more exhuastive document or to a short example code for addressing in the following situation:

I have 3 devices, how should I set their address, so that they can communicate via broadcast and unicast with each other?

Thanks in advance

Hi,

You can find the address configuration for the RADIO here:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/radio.html?cp=2_1_0_22_3#concept_mdy_kcj_4r 

It depends on BASE[0..1] and PREFIX[0...7] registers. Such that if BASE0 = 0x12345678 and PREFIX0 = AB, then it can receive any packet with the address 0x123456789AB.

I think the ESB library is the possible "easiest" implementation and usage we have the RADIO:

Source code in the SDK.
