SDK 15.2 API 6.1
I am advertising with 1 nRF module and trying to scan with a second nRF module and connect.
the advertiser
/**@brief Function for initializing the Advertising functionality.

the scanner

/**@brief Function for initializing the scanning and setting the filters.

}
When i start the advertiser and engage the scanner, the switch statement in the scan_evt_handler for p_scan_evt->scan_evt_id = NRF_BLE_SCAN_EVT_NOT_FOUND
the name is established for the scanner and advertiser as follows
#define DEVICE_NAME_TLBX "ABCDEF"
//for scanner
static char const m_target_periph_name[] = DEVICE_NAME_TLBX;
//for advertiser
strcpy(device_name, DEVICE_NAME_TLBX);
...
err_code = sd_ble_gap_device_name_set(&sec_mode,
device_name,
strlen(device_name));
APP_ERROR_CHECK(err_code);
...
init.advdata.name_type = BLE_ADVDATA_SHORT_NAME;
init.advdata.short_name_len = DEVICE_SHORT_NAME_LEN;
How come i get evt not found error instead of connecting? Also why does the switch statement break when the event is event not found. The switch statement never enters default and it goes into a break point infinite loop. It never enters the NRF_BLE_SCAN_EVT_NOT_FOUND case.
