Hi

I use an avr attiny441 with the nRF24AP2 (ANT) from nordicsemi. Communication is over SPI byte flow. After start up, I get the start-up-message from ANT. That's fine. Afterwards, when I want to assign a channel or set a Channel ID or everything else, I dont get any response messages from ANT2. I think, the communication works, because when I send the messages above, I get the sync-byte from ANT 0xA5, afterwards just 0xFF, and at the end of the packet ANT pulls SEN to high. But afterwards, I never get any responses from the ANT, the ANT never pulls SEN to low to show me that ANT has any messages (in this case response message) for me.

Does anyone know anything about my problem?

Thanks.

Hi,

Are you able to provide a logic analyzer view of your communication?

Thanks
