I found it in one of the discussion that,
TGAP_LIM_ADV_TIMEOUT controls how long you advertise when GAP_ADTYPE_FLAGS_LIMITED is set. The documentation states "Maximum time to remain advertising, when in Limited Discoverable mode. In seconds (default 180 seconds). "
So,3 min is the default
But I cant understand how to minimise it. I search lots of but do not find the code line for setting the TGAP_LIM_ADV_TIMEOUT. Please tell me how to minimise default timeout time
