https://devzone.nordicsemi.com/f/nordic-q-a/36008/nrf52-scanning-problemHi, 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 numberen-USTelligent Community 13Tue, 03 Jul 2018 08:05:09 GMThttps://devzone.nordicsemi.com/thread/138684?ContentTypeID=1Tue, 03 Jul 2018 08:05:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f4f8f46d-040c-4d8e-b19c-0311a49378d6Bastien Reynard<p>What are your scan params (ble_gap_scan_params_t)?

I think your main problem is to find out why the scanner is stopping. Without more code snippets and more information on your device , it is very difficult to analyze. I would recommend you to debug this from application side as it is less likely to be a BLE stack side issue.</p><div style="clear:both;"></div>
