I am considering adding Bluetooth to a piece of test equipment I am designing. I am not really very familiar with it, but it seems to be pretty easy to implement by connecting a transciever module to the microcontroller RX/TX lines and having the PC find it and then using it as a wireless serial port. I just purchased a little Bluetooth 4.0 USB dongle for the PC (only $12) and I ordered a module for the PIC controller of the test set:
I'm fairly sure it will not work encased in an aluminum box with a 1/8" aluminum panel, although possibly the signal could get in and out through some openings that are locked only by an LCD display and other components. I will probably need to expose the antenna, or add one that might even be incorporated into the panel overlay which has a membrane keypad. We may need to redesign the panel and perhaps an antenna could be added, but otherwise (and for the prototype), perhaps I can just cut a rectangular slot for the antenna portion of the PCB to be exposed, and maybe add a plastic cover to protect it.
Has anyone had any experience with these modules, or others, and specifically using them in a metal enclosure?
And is it possible to use the WiFi controller built into the PC (Toshiba
Satellite C655) for Bluetooth?
I did not find any Bluetooth adapters in Device Mangler and when I plugged in the USB adapter it enumerated and installed automagically. But I don't have any Bluetooth devices to test it with.
It installed as follows:
(Bluetooth Radios) Broadcom BCM20702 Bluetooth 4.0 USB Device Microsoft Bluetooth Enumerator
(Network Adapters) Bluetooth Device (Personal Area Network) Bluetooth Device (RFCOMM Protocol TDI)
I don't see it listed as a COM port, but maybe it first needs to be paired with a slave device.
