Recommended scan interval and scan window for scanning more beacons | nrf sdk 15.2

[sowmiya]

I am using NRF SDK 15.2 SDK for development , Im trying scan more beacons ,

static ble_gap_scan_params_t m_scan_param = 
{
.active = 0x01,
.interval = 0x0100 ,
.window = 0x0050 ,
.filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL,
.timeout = 0x0000,
.scan_phys = BLE_GAP_PHY_1MBPS,//|BLE_GAP_PHY_CODED,
.extended = 1,
};

SCAN_INTERVAL[0x00A0 - 100ms] ,SCAN_WINDOW[0x0050 - 50ms] ,SCAN_DURATION[0x0000]

SCAN_INTERVAL [0x0100 - 160ms] ,SCAN_WINDOW -[0x0090 -90ms] ,SCAN_DURATION[0x0000]

I have setted scan interval and scan window has mentioned above.per second it scans 70adv packs to 110 adv packets,

what is the recommended way to set scan interval and scan window to scan more number of beacons ? How much it can acheive ?

Thanks in advance!

Hi,

what is the recommended way to set scan interval and scan window to scan more number of beacons ?

If you are only doing scanning, you can set the scan-window equal to the scan-interval. Then the radio will then be scanning ~100% of the time.
