Recently used Processing application SynchArduinoClock to set RTC in Arduino sketch via USB / COM link.
Now working on menu driven app and looking into putting the menus in PC AND replacing the hardwired link with Bluetooth.
Seems doable.
Anybody done that and has some pointers / references for me?
I'll let Mr google do some search also.

It should be pretty straightforward.
Get like an HM-05 bluetooth module. It shows up as a bluetooth COM port on the computer side, and communicates as serial on the other side (as you'd expect). Usually these come ready-to-go, saving you even the effort of configuring the adapter. The things are dirt cheap too.
I've never used bluetooth with Arduino, only Espruino, but i see no reason it couldn't be used to replace serial there. I don't know if you can program the Arduino over it, though - I don't know if it gives you a DTR pin like the FTDI adapters use to reset the Arduino for programming.
It is fairly simple to get an Arduino to connect to a PC / Smartphone via Bluetooth. You can find Bluetooth transceiver modules on e-bay for about $4-5 (HC-05, or HC-06 would work). There are many tutorials online and on this forum. I documented a couple of my projects here: Search Results for “bluetooth” – 42 Bots
Also, there is a cool module sold by Adafruit that automatically detects baud rates and has a DTR/RTS/DSR pin, so you can actually use it to program your Arduino via Bluetooth:
Thanks for all the references, it is very encouraging and helpful.
Did not expect such prompt reply.
I see only one minor “challenge” - I need to interface with existing Arduino hardware so will have to go with “USB to Bluetooth” dongle.
