SPI returns 0x0F on any request after random period of time

Sergy

Hi, im using nRF24L01+ to constantly transmit data and all working fine, but at some point SPI fails and the only returned values I get are 0x0F - doesnt matter which register I try to read or write. Any idea why is that happening?

Thanks, Sergey

    Hi,

    Can you provide us with a bit more information?

    1. Does this happen on other nRF24L01+ that you're testing with?
    2. What SPI freq and voltage is used?
    3. Have you scoped the SPI-lines to see that the signal is nice and clean, and verify that 0x0F is going over the bus?
    4. Does every read-command return this, even read pipe address?
    5. When this happens, is it possible to recover by flushing RX and TX pipes?

    Best regards Håkon
