RE: Changing the GAP parameters and advertising interval at run time from Peripheral device side(which is advertising)

Aswati Vijaykumar — Tue, 28 Jan 2020 05:26:56 GMT

Hi Vidar,

In my BLE project I want to get the advertising interval displayed in log file, I'm also varying the advertising interval at runtime for more than two values.

Please share a logic to measure the time period between the advertising packets. Please help as soon as possible.

Thanks & Regards,

Aswati

Hi Aswati,

I'd recommend using the Connection Parameters Negotiation module to manage the connection parameter negotiation with the central. It includes APIs that let you request new connection parameter at runtime.

The Advertising Module already includes a fast and slow advertising mode allowing you to specify two different intervals and durations. The fast mode is usually set with a short timeout and short interval when both modes are enabled. The module switches over to "slow" advertising when fast advertising times out. The SD advertising API must be accessed directly if you need a more flexible solution.
