RE: How to setup nrf51(PTX) to nrf24L01+(PRX) ?

Hi,

On the nRF24L-side you have to ensure that the configuration matches what you've set on the nRF51-side.

I would recommend starting with the "plain" example in the SDK (more or less what you have now), then start modifying your nRF24L-side to match the settings on the nRF51-side. In your example, you're sending on PIPE3, try with PIPE0 instead.

Proposed configuration changed (should be equal on both sides):

Setting 2 byte CRC
Setting payload length on your PIPE0 to 32 bytes
Setting RF channel to '15'
Enabling dynamic ACK (See FEATURE register, field "EN_DPL" in nRF24L01+ datasheet)
Setting the RF Address equal (by default; 0xE7E7E7E7 in both examples)

Cheers, Håkon
