I have an Android app need to discard the mDNS packet once the all information is retrieved. But the Android nsdManger cache it too long.
By wireshark, I found the mDNS packet sent by CC3000 actually asks to cache it for 1 hour, 15 minutes. Is there anyway I can change it to 10 seconds? Thanks.
below are parsed info from wireshark:
