I have a bluetooth 1.1 module, the pin3 should be connected to PIO1, pin 6 should be connected to Reset, in G120HDR, which pins are PIO1, and should I really connect the pin 6 to pin RESET?
@ sf9054 - Where did you see PIO1?
The G120HDR is not meant to be used as a Gadgeteer mainboard. It is an evaluation module for the G120 that provides a few Gadgeteer-style sockets to ease certain development tasks, like using a display.
If you want to use the Bluetooth module with it, you can either port the driver to NETMF and define the pins as needed based on your requirements or you can define your own socket and pass it to Gadgeteer and then physically wire the module to the board to match that socket. The available user socket may help with that.
Pin 3 on the Bluetooth module is used as the status interrupt and pin 6 is indeed the reset pin for the module. You can see the driver source here: https://bitbucket.org/ghi_elect/gadgeteer/src/d1ccb4cec36087bef643e6d73194be51fe4688c9/Modules/GHIElectronics/Bluetooth/Software/Bluetooth/Bluetooth_42/Bluetooth_42.cs?at=SDK-2013-R3
