How to set sd_ble_gap_scan_start() scan parameter for 1M-PHY and LE-Coded-PHY on SoftDeviceV6.1.0

[loquat]

nrf52840 SoftDevice V6.1.0 release-notes written,

The scanner and initiator roles can now be configured to receive ADV_EXT_IND PDUs on both 1M and Coded PHY, using
a single call to sd_ble_gap_scan_start() or sd_ble_gap_connect()


I try sd_ble_gap_scan_start() follow params

    .extended                    = 1,
    .report_incomplete_evts        = 0,
    .active                        = 1,
    .filter_policy                = 0,
    .scan_phys                    = BLE_GAP_PHY_1MBPS | BLE_GAP_PHY_CODED,
    .interval                    = 0x0100, /* 160ms */
    .window                        = 0x0100, /* 160ms */
    .timeout                    = 0,


But  error(0x07 NRF_ERROR_INVALID_PARAM) returns.


How to set ?

Hi!

The migration document states:

"For scanning on two PHYs, the API expects the interval parameter to be larger than or
equal to twice the scan window and the extended flag to be set to 1."

In your case the interval and window is the same value. Try setting the interval to  be (2 * window).

Let me know if that works.

Best regards,
Joakim
