CC Debugger can not be recognized

Other Parts Discussed in Thread: CC2540, CC2650, CC2640

Hello,

I would like to use CC Debugger to download an image on my CC2540 USB dongle. I bought a new CC debugger and plug it in my windows 8 laptop. The system can not recognize it and I saw the following in device manager:

I try to use SmartRF Flash programmer to update the firmware but it failed. The LED on CCD is red even I correctly connect it with CC2540 USB dongle. I tried to connect it to another windows 10 laptop but I got the same issue. Is it a hardware issue or a firmware issue? Could you please help me with it?

Thanks,

Jianlin

  • What kind of errors are you getting when you try to update with SmartRF Flash Programmer or CCS?
  • Try to use the attached driver for CC debugger.

  • Hello Yikai,

    Thank you very much for your help! I haven't work with BLE before. I would like to build a BLE GATT client which allows me to read characteristic value from another BLE device and read the value through USB port. The client can be either CC2650 LP or CC2540 USB dongle that is why I would need the CC debugger. Do you have a recommendation on which would be a easier option?
    I tried to use the CC2640 simple_server example. However, I don't know how to print the characteristic list and print the value of a characteristic. Could you kindly please tell how to do that or is there an example to follow?

    Many thanks,
    Jianlin
  • I would suggest you to start from CC2640 simple_peripheral example in BLE Stack 2.2.1. By the way, I suggest you to post BLE related issue to  Bluetooth® low energy Forum.

  • Hello Yikai,

    I posted the same question on the BLE forum. If it would be more convenient for you, we could chat there. I have already build a BLE peripheral which has a customized profile and allows people to read value in the GATT characteristic list. My next step goal is to build a central(BLE client) which could read the value every 1s and send it to Laptop though UART(USB). i could do it with BTOOL to read the characteristic value, but I have to do it manually. I know that the read/ write process are all event triggering. Could you please give me a hint on how to do that?

    Thank you very much,
    Jianlin
