Relay with buttonless dfu code stop scanning beacon with random event

[abhijit]

In our project nrf52 device scans for nrf52 beacon device throughout the day. It scans number of beacons available and send it to esp32 device on serial. that is how its working. The problem is sometimes it stop scanning beacon and sends number of beacon 0 even if beacons are available it happens continue until restart.I have tested from hardware side and its okay but i think there is a problem from BLE Stack side.

i am using following scan parameter,

.extended = 1,
.active = 1,
.interval = SCAN_INTERVAL(0x640),
.window = SCAN_WINDOW(0x640),
.timeout = SCAN_DURATION(0),
.scan_phys = BLE_GAP_PHY_1MBPS,
.filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL,

please suggest probable issue,(sdk 15)

Hi,

1. What SDK and Softdevice versions are you using?
2. Do you ever connect with the beacons or other devices?
3. Are you sure that the device stops scanning? 
4. Can you upload your code?

hi,1)sdk 15.0.0,softdevice 6.0.0

2)no,only scan beacon data in BLE_GAP_EVT_ADV_REPORT callback

3)yes,i check beacon still advertising and scanner prints its data without beacon data
