nRF51822 stop advertising to save power

[AnthonyThet]

Hi currently I am handling a project in which I used nRF51822. I am using SDK 11 and softdevice SD130. I  want to know is there any significant difference in power consumption if I stop advertising (actually the device cannot go into system off power mode) to save more power and if so , how can I do it?

Whether it's significant or not will depend on the rest of the system.

So you need to do a profile of the whole system's power consumption - then you'll see how much is due to advertising and, thus, whether that's a significant contribution.

Note that you can reduce power consumption due to advertising by reducing the Advertising Interval - at the cost of "connectability" ...

Hi awneil, thanks so much for your answer. But I don't know how to properly stop the advertising. Actually when the device is charging, I want to stop the advertising because of the charging current issues and I want to advertise again (normal mode) when the charging is off. I want to stop and start the advertising properly. How can it be done?
