[Aswati Vijaykumar]

Hi Nordic Team,

Please suggest when should the event handler for scanning at central device be called to scan all the peripheral devices which are advertising.

Please help as soon as possible.

Hi VijayKumar,

It is not clear what you are asking. Can you please describe what you are trying to do in more than one line.

Hi Susheel, 

Please explain the point which u did not understand. In my BLE project there is a event handler in the central device scanning code, used to scan the peripheral devices which are advertising. But all peripheral devices are not getting scanned. Please help

Thanks & Regards,

Aswati

It depends on a lot of things Aswati,

1. The scan window and the scan interval
2. Advertising interval of the peer advertisers.
3. At every BLE_GAP_EVT_ADV_REPORT received, there is some processing done in your application while the scanner is paused. After the processing of the particular ADV_REPORT is finished, the scanner is started again. During this time, when the scanner was paused there will be lot of advertising reports missing since the scanner was not sniffing at all.

It normally helps to scan for longer times and start the scanner in the BLE_GAP_EVT_ADV_REPORT very fast.
