Hello,

Strange, the link works for me. It is pointing to the Softdevice specification (https://docs.nordicsemi.com/bundle/sds_s140/page/SDS/s1xx/radio_notif/radio_notification.html). Could you try to access it again?

[quote user="hiroiwas"]The scan interval is 20ms, the window is also 20ms, and the radio notification distance is 5500 us.[/quote]

This means you are scanning 100 % of the time. Please try to set the window size to 10 ms.

Best regards,

Vidar

Hello, Vidar.

Thank you for your quick reply.

The link you provided was unconfirmed.

I was referring to the offline documentation.

nRF5_SDK_17.1.0_offline_doc.zip

> What is the duty cycle of your scanning?

The scan interval is 20ms, the window is also 20ms, and the radio notification distance is 5500 us.
And the beacon (advertising) interval is 100ms.

Best regards.

Hello,

You may have seen it already, but the radio notification feature is described in more detail in the Softdevice specification. What is the duty cycle of your scanning? There must be time between the scan windows for the radio notification signal to be available.

Best regards,
