sometimes, the two port numbers are not sequential In testing, we find that COM port 8 is actually the incoming port. When pairing with Windows 7, we see that COM port 7 is assigned. although we know, from experience, that this isn't always the case. Normally, Windows XP assigns the outgoing port first, and then assigns the next ordinal port number to the incoming port. Is actually the outgoing port, not the incoming port. we can get it to work, but the process reports back only one virtual COM port number, which we have discovered empirically However, in testing with Windows 7, we have discovered that the Bluetooth pairing utility is now different from the one used in XP.
Our product uses the 'incoming' COM port, since it autonomously initiates a commuincation. In Windows XP (as well as Vista), the 'Bluetooth Devices' dialog box shows, after pairing, the COM port assignments for both 'incoming' and 'outgoing'ĬOM ports. So…do I abandon that and just use XBee and Arduino?ĭo I need the serial cable at all (initial setup, etc.My company has developed a Bluetooth product that uses the serial port profile via a virtual COM port. I could replace the header as I have some stock headers of the same size (for my XBee projects), but honestly I’m just not confident in the comms hardware.
I would like to get to using the bot this weekend as I haven’t used it at all yet, other than building it. When I plug everything in, the Bluetooth board does receive power, but the RSSI light is on a slow pulse when in AT mode and a fast pulse otherwise, and the PC does not see it at all, so none of the software works. The Bluetooth board that came with the SCS is manufactured badly, causing the Bluetooth module to not be able to sit flat in the socket as there is something in one of the socket headers…maybe a solder spill over. Now I have them, and I am running into another problem. It is made by Cambridge Radio and took me a lot of time and MANY forum searches to find the real drivers for it. I just bought a BRAT and was at first a little annoyed by the lack of information on the Bluetooth dongle that came with it.
