how to set the advertising intervals to 30 seconds?

[ALE]

Hi,

I am using the nRF52-DK as a device like beacon encodded with the original code of "nRF5_SDK_13.0.0_04a0bfd\examples\ble_peripheral\ble_app_beacon. I want to change the advertising intervals to 30 seconds. However, the maximum advertising intervals is limited to 10.24 seconds.

Would you please tell me how to change the advertising intervals to 30 seconds?

Thanks in advance! Best wishes

You can't. The Bluetooth spec says 10.24 seconds is the maximum for undirected advertising so 10.24 seconds is the maximum the softdevice (which is BLE compliant) will allow you to set.

But if you really want to go outside BT SIG specification for GAP then you can set your application timer to 30s, then start advertising and timeout immediately after first packet goes out.
