Recently, I try to programme nRF51822 DK communicating with nRF2401e1 DK,unfortunately,which does not success. With setting radio configuration: TXPower,frequency channel, data channel,address,and other paras, It still didn't work. So I want to ask if they can communicate or compatible each other, or yes,but what should I pay attentinon to? Thanks so much ! wish your reply as soon as possible.
