Sensor Tag cc2650 has updated firmware (1.12), can pair with windows 8.1, but cannot view data

Other Parts Discussed in Thread: CC2650, BLE-STACK, CC2650STK

Hello,

I have the Sensor Tag cc2650 and I have updated the FW using the iOS app. I am now able to pair the Sensor Tag with a Surface Tablet (Windows 8.1) but am not able to view anything off the sensor tag in BLE Device Monitor. Am I doing this incorrectly?

Thanks,

Anton

  • Hello,

    It's not clear from your description which BT component you are using to establish a connection to the SensorTag (STK). The BLE Device Monitor (DM) is designed to work with the CC2540USB dongle and not the built-in host stack of the Win 8.1 machine. Are you able to establish a valid COM port connection to the CC2540USB dongle?

  • Hi JXS,

    I did not know that a bluetooth dongle was needed. The forums and information provided about cc2650 stk is not clear regarding it's compatibility with windows. If my cc2650 has updated FW 1.12, I can pair it with a Windows 8.1 computer. Am I able to view the data off the sensortag through another program (such as the DM)? Do I need a dongle specifically for this sensortag? 

    Regards,

    Anton

  • Hello Anton,

    If you use BLE Device Monitor PC application, the CC2540USB dongle or CC2560DK running HostTestApp is required (hex file provided in the BLE-Stack SDK). You are certainly free to write a BLE-compliant application that communicates with the SensorTag using the Win8.1+ host stack that supports BLE. The profile for accessing the SensorTag's peripherals is published on the TI BLE wiki and www.ti.com/sensortag.

  • Hi JXS,

    A few more questions.

    1) In order to use the BLE DM, I will need to purchase the dongle or this controller (www.ti.com/.../cc2560;tisearch=Search-EN-Everything). The latter would require installing HostTestApp (is this a separate program I have to find or does it come with the BLE stack) and using the hex file from the BLE-Stack. The controller is for cc2560DK, not the cc2650STK (actual sensor tag) correct?

    2) Where do I get the Win8.1+ host stack that supports BLE? What is a "host stack"?

    3) I assume that accessing the peripherals (through change of code using CCS 6.1) would allow me to stream from the sensortag to a custom designed program?

    Thanks for your help.

    Anton

  • Hello,

    HostTestApp comes pre-built with the BLE-Stack, refer to the BLE SW Developer's Guide. Just to clarify, the BLE Device Monitor only works with the CC2540USB dongle.

    For developing BLE apps on Win 8.1 that use a Windows compliant BLE controller, you can refer to this post: stackoverflow.com/.../developing-for-ble-windows-8-1 which was found via a simple web search for "windows 8.1 ble stack". Ironically, it uses SensorTag as an example :)
