the BLE spec has a notion of
reading/writing "long values" -- values bigger than a packet (22
bytes) -- by transmitting an "offset" parameter as part of the
request.... there is support for this capability in the BLE
staick available with the TI CC2540, for instance, which i'm
using for testing...
is there support for this feature in the new Core Bluetooth
framework??? at present, i can read characteristic values of
length 20; but reads of characteristics of length 25 never
invoke the method in the peripheralDelegate.... is there some
other API and/or procedure i need to follow to read
characteristic values larger than a single packet....
along these lines, the BLE spec also talks about procedures by
which central and peripheral can "negotiate" an MTU (packet)
size.... is this supported as well???
thanks in advance.
bob.
