Could you let me know where I can read the connection interval in above sniffer logs? I opened two logs in a wireshark (v1.10.14) but I could not find where the information of the connection interval is. Thank you in advance.

MIN and MAX to 7.5ms did the trick.

From your sniffer logs, i read a connection interval about 10 times higher when connecting to the S120 device. Try setting both min and max to 7.5 ms.

According to pcap files you provided, when doing connection between s110 and s120 Your connection interval sets to 75ms (not 7.5). When connecting with android, connection interval is 48.75ms. Try setting both MIN and MAX connection interval on your s110 to 7.5ms so You will have it for sure.

Also, s120 does not support receiving multiple packets per one connection interval - many android phones do support it (ex. my galaxy S4 does about 3 or 4 packets per connection interval), so throughput is much better.
