The scanning operation itself for bluetooth will receive packets from every device every time it sends out a "scan" ping. It could very well be that you aren't filtering the scanning packets to ignore/discard repeated scan response packets from the device(s).
Yes, that's true; however, it appears that the packets are supposed to be filtered in the example:
BLEManager.StartScan(new CyBleScanSettings(CyScanType.PASSIVE_SCAN, DEFAULT_SCAN_INTERVAL, DEFAULT_SCAN_WINDOW, CyInitiatorAddrType.PUBLIC, CyScanInitiatorFilterPolicy.ACCEPT_ALL_ADV, CyDiscoveryType.OBSERVATION_PROCEDURE, DEFAULT_SCAN_TIMEOUT, CyScanDuplicateFilterPolicy.ENABLE_DUPLICATE_FILTERING), ScanCallBack);
CyScanDuplicateFilterPolicy.ENABLE_DUPLICATE_FILTERING should enable scan advertisement duplicate filtering.
Hmmm, I haven't run into this. Perhaps someone else has input? :)
So far I haven't seen this issue in that example. Have you done any modification to the project? If so what are those? Can you please attach your modified code here?
No, I have not modified the project at all.
