CC2531 USB Dongle not detected

Other Parts Discussed in Thread: CC2531, Z-STACK

When I plugin CC2531 USB dongle to my laptop, no new hardware is detected. I have two CC2531 USB dongles, both behave the same. When plugging in, LED2 blinks once and then goes off. What is the issue? Do I need any additional hardware? I guess it is not a driver issue, since I can't find any hardware to install the driver for.

Thanks in advance.

  • Hi,

    CC2531USB must be programmed with suitable firmware. For example with CDC-ACM driver, or HID for it to be recognizable by OS.

    I think that the most straight forward approach to test your CC2531 USB dongle, is to program it with packet sniffer firmware which distributed along with smartRF packet sniffer

  • Hi Awai,

    If you want CC2531 usb dongle act as sniffer HW, you can try to flash sniffer_fw_cc2531.hex into your dongle with CC debugger. The hex file "sniffer_fw_cc2531.hex" would be in C:\Program Files\Texas Instruments\SmartRF Tools\Packet Sniffer\bin\general\firmware after you install TI packet sniffer.

    IF you want CC2531 usb dongle act as ZNP, you can flash ZNP hex file. The ZNP hex file is in C:\Texas Instruments\Z-Stack Home 1.2.0\Projects\zstack\ZAP\ZNP-HexFiles after you install Z-Stack Home 1.2.
