NRF24L01+ RX_ADDR_P0 and TX the same address?

[SKRIM]

I'm planning on testing an rf link with just a pair of NRF24L01+. Having battled with the PTX side and got that working i'm looking at pipes an addresses.

An answer to a another question on here suggest that power on defaults for two chips should be sufficient for the two to communicate?

The power on defaults are RX_ADDR_P0=0xE7E7E7E7E7, RX_ADDR_P1=0xC2C2C2C2C2 and TX_ADDR=0xE7E7E7E7E7.

It seems counter intuitive to me that one chip would have the same TX and RX address as another.

Hi,

This is to ensure that the AUTO ACK-ing feature of the Enhanced ShockBurst (short: ESB) is working. ESB requires you to use the RF_PIPE0 as the reception pipe for the ACK.

This means that if you want to send w/ACK you must always ensure that RX_ADDR_P0 = TX_ADDR.

Cheers, Håkon

Also tried with RX_PW_P0-6 = 0x03 0x03 0x00 0x00 0x00 0x00 still no data received.
