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,

    Are you using two of those modules for communication? if yes; how far are they from each other?

    Those modules have a PA on them, which will then send with 20-30 dBm output. The receiver LNA (low-noise-amp) will be saturated at >0 dBm (0 dBm = max input), which can explain why you are getting strange behavior.

    Best regards Håkon
