sd_radio_session_open()

uint32_t sd_radio_session_open

(

nrf_radio_signal_callback_t

p_radio_signal_callback

)

#include <nrf_soc.h>

Opens a session for radio timeslot requests.

Note

Only one session can be open at a time.

p_radio_signal_callback(NRF_RADIO_CALLBACK_SIGNAL_TYPE_START) will be called when the radio timeslot starts. From this point the NRF_RADIO and SD_TIMESLOT_TIMER0 peripherals can be freely accessed by the application.

p_radio_signal_callback(NRF_RADIO_CALLBACK_SIGNAL_TYPE_TIMER0) is called whenever the SD_TIMESLOT_TIMER0 interrupt occurs.

p_radio_signal_callback(NRF_RADIO_CALLBACK_SIGNAL_TYPE_RADIO) is called whenever the NRF_RADIO interrupt occurs.

p_radio_signal_callback() will be called at ARM interrupt priority level 0. This implies that none of the sd_* API calls can be used from p_radio_signal_callback().

Parameters

[in]

p_radio_signal_callback

The signal callback.

Return values

NRF_ERROR_INVALID_ADDR	p_radio_signal_callback is an invalid function pointer.
NRF_ERROR_BUSY	If session cannot be opened.
NRF_ERROR_INTERNAL	If a new session could not be opened due to an internal error.
NRF_SUCCESS	Otherwise.
