Hi, I'm currently working on a bachelor project and need to wireless transfer data from microcontroller (got PIC18F25K80) to computer. I just bought the BTM431 bluetooth module from Lairdtech and was wondering what to do with pin 3 and 5? I have confirmed that serial communication works over RS232, but I'm not sure what to do to atleast get contact with the device. I'm not totally sure, but I only need PIN 2-6(for serial data communication) and 12-14(for supply voltage) Would really appreciate some help, starting to run out of time
