Hi!
We are using ble_radio_notification for changing the advertisement data after every advertisement.
The problem is that it doesn't work, the device freezes when trying to do this.
Here are some code snippets that might give you a better understanding.
void radio_notification_evt_handler(bool radio_evt)
{
if (radio_evt) {
//radio going active
//turn on LED
LEDS_ON(BSP_LED_2_MASK);
} else {
//radio inactive
//turn off LED
counter += 1;
LEDS_OFF(BSP_LED_2_MASK);
advertising_set_data(&counter, sizeof(uint8_t)); // This is where we die!!
}
}
All we want is to set a number that is increased by one for every advertisement. So this is the code that tells us when to "update" the advertisement data, it is initialized by:
err_code = ble_radio_notification_init(RADIO_NOTIFICATION_IRQ_PRIORITY, NRF_RADIO_NOTIFICATION_DISTANCE_5500US, radio_notification_evt_handler);
where priority is 3 and the distance at the moment is 5500us (all combinations tested).
advertising_set_data looks like this
static void advertising_set_data(const uint8_t* p_in_data, size_t dlen)
{
uint32_t err_code;
ble_advdata_t advdata;
ble_advdata_t scanrsp;
ble_advdata_manuf_data_t manuf_data; // Variable to hold manufacturer specific data
uint8_t data[8] = {0};
memcpy(data, p_in_data, dlen); // Our data to advertise
manuf_data.company_identifier = 0x1337; // "Random" company id
manuf_data.data.p_data = data;
manuf_data.data.size = sizeof(data);
ble_uuid_t adv_uuids[] = { { LBS_UUID_SERVICE, m_lbs.uuid_type } };
// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = true;
advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
advdata.p_manuf_specific_data = &manuf_data;
memset(&scanrsp, 0, sizeof(scanrsp));
scanrsp.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
scanrsp.uuids_complete.p_uuids = adv_uuids;
err_code = ble_advdata_set(&advdata, &scanrsp);
APP_ERROR_CHECK(err_code);
}
It is only when we do this in radio_notification_evt_handler that the device dies/freezes. Doing it in for example here doesn't give us this issue.
// Enter main loop.
for (;;)
{
power_manage();
advertising_set_data(&counter, sizeof(uint8_t));
}
All feedback that could help us avoid this issue is greatly appreciated.
