Have you enabled wakeup on those pins through the WUOPC0/WUOPC1 registers? Also, what package type do you have? The 48-pin package does not allow you to enable wakeup on pin on P0.3 and P0.4, but the 32 and 24-pin packages do.

Wakeup on most pins is active high only. Are your buttons active high or active low?

Hello

Thank you very much for the reply!

I did try your code, it kind of worked, but it was not fast enough. The delay after I pressed the button was around 1.5 seconds and about 20% of the clicks did not COMe through at all.

The datasheet says that wake up time should be around 1ms...

Just to clarify, my setup is following: I have a transmitter with buttons connected to pins: P0.03 and P0.04 and reciever has LEDs connected to the same pins.

Do you know what might be the probleem, how to get rid of the delay ?

Thanks in advance !

Arvo

Hi Arvo

I haven't played much with the nRF24LE1 lately, but I had a go at modifying the ESB TX example to use RTC sleep.

You will find the result attached: main.c

Can you give that a try?

I tested it briefly, and verified that it sent a packet every second as expected.

Best regards
