Hi, I am using nRF51822 with Softdevice S110 v6.0 to advertising packets and I would like to know when transmission is over to read some data from external sensors. I tried to use radio notifications but they seem to work incorrectly. To check it i put into handler two functions to send info about radio state to terminal and i discovered that interruptions are triggered constantly couple times per second independently to advertising interval (i set the longest available period 10,24s, so i think that interrupts with the same radio state should be triggered with approximately this interval). Below I attached my functions to handle radio notifications and i would like to know what is wrong with them.
/**@brief Function for handling radio notyfication.
*/
void ble_radio_ntf_handler(bool radio_state)
{
if(radio_state==true)
{
// Radio active.
simple_uart_put('a');
}
else
{
//Radio inactive.
simple_uart_put('i');
}
}
/**@brief Function for enabling radio notyfication.
*/
static void radio_notification_init(void)
{
uint32_t err_code;
// Enable Radio Notification
err_code = ble_radio_notification_init(NRF_APP_PRIORITY_LOW,NRF_RADIO_NOTIFICATION_DISTANCE_800US,ble_radio_ntf_handler);
APP_ERROR_CHECK(err_code);
}
