Advertising stops every ~15minutes

[JeanMBoones]

Hello, 

I want to do fast advertising (100ms) (LE privacy enabled) for about a minute, then I want to transition to slow (1000ms) advertising forever (or until a connection starts).  The fast to slow transition works fine, but even if I put a very large value for the slow advertising duration, it always seems to stop every ~10-15 minutes.  I need to restart it to keep going.  Is this the normal behavior?  Is there a way to advertise forever?

Hi,

Set the timeout to 0 for unlimited advertising.

Also make sure that you use general discoverable mode.
 

init.advdata.flags                   = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
