About nRF51822 scan window and scan interval

[Wisem]

Hello,

I am using nRF51822, SDK12.3.0, pca10028, S130 as a central scanner.

Now I set the scan interval to 100ms and the scan window to 50ms. It is planned to use 50ms to scan ADV data, calculate it in the other 50ms.

And the question is, how to learn the state after every scan window, so I can deal with receive data immediately? Or maybe like the BLE_GAP_EVT in function  on_ble_evt() ?

Thanks.

Hi,

You will get BLE_GAP_EVT_ADV_REPORT events during the scanning, for each advertisement scanned. See the Scanning message sequence chart, and the documentation for sd_ble_gap_scan_start().

If handling of the received advertisements requires some computation, then you may want to handle the event in main context. For that you can use the Schedule handling library.
