Is writing nRF24L01+ status reg. executable only in standby?

I would have to assume most people just copied existing examples ;)

I don't know of any other configuration registers that can be changed without going into standby, no.

As you say, all the other commands can be issued at any time, including the commands for flushing buffers and reading/writing payloads.

I'm also very surprised by your answer. It makes me wonder how everyone "just knew" to ignore both directives in the datasheet!

Are you aware of any similar undocumented exceptions to registers that can be written to without being in standby or power down?

As I understand it now then, all SPI commands listed in table 19 can be executed at any time - with the exception of W_REGISTER write-addressing any register other than Status. Can you confirm that this is an accurate representation of the hardware?

Hi Adrian

It is safe to clear the interrupt bits without leaving TX/RX mode, and this is the recommended way to do it. As you noticed it's not very practical to disable the radio every time you need to clear interrupts.

I was surprised to hear this is not written in the datasheet, but I can't find any descriptions of it either. This should have been described better for sure, but I doubt this will be changed after all these years unfortunately ;)

Best regards
