how to set timeout for radio receive function ?

[Mehmet Nuri]

Hi everyone,

I use the radio example as my basis. I call the read_packet() function from receiver example. And there is no incoming data, it stucks there. How can i set a timeout so that it continues to operate right after the function ?

Hi,

 

That is not included in the basic radio examples. If you add a timer instance to your example, you can use that as a timeout source.

However, if you need auto-ACK, re-transmissions, and other basic features, I'd recommend that you look at the ESB (Enhanced ShockBurst) examples.

 

Kind regards,

I have set an app_timer instance but when that instance occur, it takes approximately 20 seconds to operate again. this is my handler function:

static void radio_timeout_handler(void * p_context){
	
		NRF_RADIO->TASKS_DISABLE = 1U;
		
    while (NRF_RADIO->EVENTS_DISABLED == 0U)
    {
        // wait
    }
		
		
}

Hi,

 

You should not implement the while loop in the timer handler.

Set a variable there instead, and check it in the original while-loop.

 

As mentioned, if you require such functionality, please see the ESB examples, as this includes basic functionality like re-transmission and so forth.

 

Kind regards,

okey i will check the ESB examples. By the way, i did implemented a bool in timer handler. This is the final version. I changed it a 100 times. Thanks for ESB suggestion. Will check it.
