Documentation and code states that device will continue to advertise for 30s after button is pressed. However, I'm seeing a 3 minute timeout instead. I haven't been able to determine where this 6x factor is coming from.
I've noticed that the discoverable mode is set to GAP_ADTYPE_FLAGS_LIMITED. Is this the default timeout for limited mode?
Changing the mode to GAP_ADTYPE_FLAGS_GENERAL doesn't seem to do anything other than to make sure that the advertising never stops. Is there a way to control the advertising period from within the stack or do I need to set up a timer to turn it off and on? The gapRole_AdvertOffTime looks like it is meant to be the time that the advertising stays off, but the code never sees a GAP_END_DISCOVERABLE_DONE_EVENT. What kicks this off?
I've tested this with both the 1.3.2 and 1.4 images with the same results.
