Hi Noboru

There is no way to change this interval unfortunately. The SoftDevice allows you to configure which of the three channels to advertise on, but not the interval between advertise packets on the different channels.

The delay between each transmission is 500us.

You can see how this breaks down using the online power profiler.

Essentially the 500us delay consists of four stages:

1) TX to RX switch
2) Receive window (to listen for scan requests and connection requests)
3) Standby period
4) TX rampup to prepare for the next transmission

Best regards
