Hi Kenneth,

Thanks for the reply,

In this ant_state_indicator.c Line 133 :

case EVENT_RX_SEARCH_TIMEOUT:
									 //Rixtronix LAB
								   //8 Sept 2021, 
								   //on search timeout, and idle, make device on if there is a signal from sensor ?
									  NRF_LOG_INFO("EVENT_RX_SEARCH_TIMEOUT...\r\n");
                    //err_code = bsp_indication_set(BSP_INDICATE_IDLE);//default
								    err_code = bsp_indication_set(BSP_INDICATE_SCANNING);
								    nrf_pwr_mgmt_feed(); //Function for indicating activity. 
								     
                    break;

Which variable is being used for increasing the timeout ?

Thanks

You can just restart searching on timeout.

Is it possible without button, so the system is always on search for peer device ? how ? thanks

I guess you will need to setup a wakeup on button press or for instance wakeup on app_timer, such that after the user press a button or after app_timer expire that the application will open the ANT channel again to try to search for the peer device?

You can find an example here on how to configure app_timer to wakeup:
