Situtation: when we search the BlackBerry's SDP server, they pop up and ask for pin. They seem to be very secure minded. hciconfig hcio noencrypt sdptool browse --tree will cause the BlackBerry 7290 to pop up the pairing screen (PIN). hciconfig hci1 feature shown the dongle (BroadCom chip) support encryption (mandated feature?) There seem no way (e.g. hciconfig hci1 feature set) to fool the other side that we don't have encryption capabilities (not sure if it is "legal" as this might be an mandated feature). Any suggestion? Anyone? Edwin
