Hi, Thanks for your advice, it was really helpful, I have already implemented in a way you told me.

Hi Øyvind,

Thanks for your response. I change to TIMER1 it doesn't help. I can debugg and see that the program enters to a interrupt handling function and I assume It should set flag1 to 1. But when it returns to a while loop it doesn't break the loop, I really don't understand why. I even tried the same example by removing radio and using only the timer, but no difference. I would really appreciate any advice.

Thanks Gor

Hi,

Since you're not receiving any packets the radio is not going to send an EVENTS_END, but instead it will wait for a packet to come. You can see that this stalling in while(NRD_RADIO->EVENTS_END == 0U) occurs in the base receiver example as well. A solution for this is to add a timeout, a set amount of time that your radio will listen.

In pseudocode: while(NRF_RADIO->EVENTS_END == 0U && some_counter < some_number)

Best regards,

Øyvind
