hi,
i'm running ios 6.1.2 on my
iphone and recently noticed
that the default connection interval -- assuming i don't request a
parameter update from my peripheral -- is 29ms according
to my
packet sniffer; in the past, this
value was in the 100ms range....
experimenting a little, i
found that i could send a
parameter update request with a minimum
connection interval of (8 * 1.25ms) and a maximum connection
interval of (16 * 1.25) and the iphone
would *accept* this request and change the connection
interval to 18ms
(15 * 1.25).... isn't this
outside of the apple bluetooth guidelines, which
require a minimum
connection interval of 20
ms (16 * 1.25ms)????
note that
requests
for shorter
intervals were
rejected....
is
this a fluke, or
is this behavior
something we
can count
on....
bob.
