Just purchased the SmartSDR for iOS app and can't get the app to find my 6500. Have tried "discover" "scan" and "fixed" settings but none connect. "Discover" just shows the whirly icon indefinitely, "scan" shows "nothing found" and "fixed" shows "seach error" after entering the IP address of the radio. The radio works fine with a cable to the PC and the PC has a solid wifi connection. Any ideas?
