ESB How to retreive the sender address

[Gaétan]

Hi,

I use ESB protocol, and all is working fine :)

Now I want to retreive the address of the sender because I can have multiple sender in my network.

I can add this in payload, but if possible I prefer to get the adress used in the radio packet.

Regards, Gaétan

You can get this information from examining which pipe the packet arrived on.

Example RX configuration:

• base_address_0 = 0x12341234
• base_address_1 = 0xabcdabcd
• pipe0_prefix = 0x01
• pipe1_prefix = 0x02

A packet arriving on pipe0, the TX address is 0xabcdabcd01

A packet arriving on pipe1, the TX address is 0x1234123402

Thank You Jørgen,

Sorry for this question:

all packet received on pipe1 have the same adress ?

I have multiple sender with the same firmware, the IC internal address is not used ?
