Do you have a modified BlueZ attribute server > or another GATT server? There are no changes required to gatttool. The implemented high level function is still to read an attribute, and the function works the same if the remote attribute is shorter than 22 octets, and will be "long" only if the first response indicates a remote attribute of 22 octets or longer. (accounting for the one octet for the response hdr) I am testing this against against the internal Qualcomm GATT server, which has been tested at the past two UPFs. This is also the same stack which I hope to use to pre-vet the SM changes you are leading, prior to the UPF in Las Vegas. As my next task, I could implement the capability to support long reads in the BlueZ GATT server.
