Ok, this isn't really a gumstix question, but maybe the hardware guys may be able to give me a quick pointer.
Got a WxWorx XM weather receiver for Christmas. Works great. Now I can get near real time radar in my airplane. Problem is, I wanted the bluetooth version but got the USB version instead.
WxWorx will upgrade it for me, but I have to send it in for their modification. And they want $200 for the upgrade.
I suspect the "conversion" consists of simply populating a bluetooth module, but WxWox won't sell me the module or tell me what it is.
I'm wondering if an adapter exists that could plug into the WxWorx receiver to convert bluetooth to USB, similar those used to provide bluetooth capability on the PC side. Of course, no driver software could be added, since the WxWorx receiver is closed architecture. And, the bluetooth interface is on the slave side, like what the gumstix-BT must implement (I guess).
Or, is there a widely used module typically used in embedded platforms that might hook up to a serial interface and provide BT capability? I can see some unpopulated modules in the unit--maybe I can "beep out" enough wires to see if the net connections are consistent with popular bluetooth modules?
Is this worth pursuing, or should I just give up and send my new unit off for a couple of weeks to get it updated to bluetooth? Maybe the firmware on the WxWorx receiver would need an update for Bluetooth support also?
Thanks for any help,
