CC2652RB: Updating advertising interval when connected, disable required?

Matt Gaidica1

Part Number: CC2652RB

It appears that if advertising is active, it would need to be disabled before the advertising interval is updated using GapAdv_disable(). However, if the connected device is modifying this value is this still true, using this prototype?

// device is connected to iOS app here
GapAdv_disable(advParams1); // required?
uint32_t newInterval = 1600;
GapAdv_setParam(advParams1,GAP_ADV_PARAM_PRIMARY_INTERVAL_MIN,newInterval);
GapAdv_setParam(advParams1,GAP_ADV_PARAM_PRIMARY_INTERVAL_MAX,newInterval);
GapAdv_enable(advParams1); // required?

Hi,

A section of our documentation is dedicated to Changing Advertising Parameters. I confirm you have to disable advertising to modify advertising interval.

Something is wrong with my implementation.

Even though advParams1 exists, I still get a 'bleGAPNotFound' as the status/response for my first line to disable it:

advStatus = GapAdv_disable(&advParams1);

Unsurprisingly, the interval is not changing (or disabling) when I test it from the central device.

Hi,

I missed some errors in the code you have shared. GapAdv_disable() and GapAdv_enable() take an adv handle (not a pointer on advParameters) as parameters. On the top of this you are missing parameters for GapAdv_enable().

Please review the link I have provided (Changing Advertising Parameters). You can also review our SimpleLink Academy labs, one specific task of the lab named "Scanning and Advertising" is dedicated to this exact topic.
