according to your email address, you work for ISSC. So you might wanna
ask some of your colleges why we can't send big packets with the ISSC
chip. I haven't found any bug in the BlueZ HCI layer, but if the data
packet is too big then your HCI goes spooky. From my understanding it is
a bug in your chip (most likely the HCI part of your firmware).

Marcel
