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

Well checking for -64 dBm wont really help, because it wont say anything about how much over -64 the signal power is. May be there is some hardware solution? Like installing a blocking diode for the RX?

The problem is that you will then degrade the receiver sensitivity as well, which affects your overall range. I would recommend that you use a lower output power instead of doing this.

You could try a power-output scaling based on the number of re-transmissions that occurs. If you have a low re-transmit count, then you scale the output power down. When it rises, you set higher output power.
