CC2640 Serial Port Profile PC Connection, UART TO BLE BRIDGE

Other Parts Discussed in Thread: CC2650, LAUNCHXL-CC2650

Hi everybody,

I am trying to connect my CC2650 Launchpad board to PC. I found that TI released a sample project that implments Serial Port Profile which runs on launchpad. When I download and run the spp_ble_server project, bluetooth manager on my PC (running windows 10) recognizes and I can establish a connection. Then, I tried to use Tera Term to send and receive bytes but I realized that there is no virtual port to connect. In other means, no virtual port seems under device manager except the ports for xds110 connection.

How can I estalish a connection between PC and TeraTerm using spp profile released by TI. The source fro spp profile for CC26xx devices is in the below link;

    Hello,

    The LAUNCHXL-CC2650 will enumerate with two virtual COM ports. You should connect to the Application UART port. Make sure any programming / debug tools (CCS, etc.) are closed and plug/re-plug may be required to re-enumerate the USB port after programming.

    Best wishes

    Hi,

    Thank you for your help. What I am trying to do is to send data from PC's bluetooth device to launchpad over SPI. I configured launchpad to blink LED whenever it receives a character. I think I do not have anything to do with XDS110 application and auxilary ports.. Or am I doing a very big mistake ? What is the use of application port in my case ? (I am just trying to send a char from PC's blueotoh device to CC2650 launchpad and blink an led on launchpad..) 

    Let me restate my problem, before doing anything,I am trying to pair my PC's bluetooth device with launchpad. However, no virtual COMM port is created when I look at Device Manager on Windows. I have done samething with many other bluetooth modules from different vendors. I was always pairing the blueotoh module with PC and the COMM port always was generated. But this time there is no COMM port generated when I check the device manager on Windows.

    Hope it is clear . Any help/ suggestion is deeply appreciated.

    Many thanks
