CC2540 USB dongle pairing

Other Parts Discussed in Thread: CC2540

Hello, all.

I am trying to receive data with CC2540DK and CC2540 USB dongle connected desktop. 

I am testing the interface set-up by support program (CC2540 Data Throughput) and serial reader program.

The paring seems fine but I need to make them be remained in paired mode to read data.

I used BTool to pair them but I can not open the COM port as it was used by BTool.

Is there proper way to record the data? 

  • Hello,

    I'm afraid I'm not able to completely understand what is happening for the description. If you can't open the COM port in BTool, then likely the CC2540USB dongle is in use by another application on your PC or the COM port number has changed. Check the Device manager for the correct COM port.

    If you paired/bonded via BTool, then you'll need to save the keys (i.e., LTK) in a text file.

    There are some PC examples on how to control the CC2540USB on the BLE wiki: processors.wiki.ti.com/.../CC254X_PC_Examples

    Best wishes
