I just opened the box with a CC2540 mini DK delivered from Digikey.
When following the user's guide SWRU270B for the BT-LE CC2540 mini devolopent kit, I expected to see the "Found new hardware" wizard window pop up when plugging in the usb dongle into a USB port of the PC. Instead, nothing happens. No device is detected.
Since a memory stick works on the USB port, I conclude that this one is functional.
I did assume, that the board comes pre-programmed?
An attempt to program the firmware with the CC Debugger also did not succeed. I did install the smart RF tool. According to the manual, a green LED should show up in the CC Debugger when powering the USB dongle from an USB port and when connecting the USB dongle to the programmer. In my setup the red LED is switched on permanently. Programming, however, of the CC Debugger itself seems to be functional.
Do these symptoms indicate that the USB dongle board is defective? Should send back the CC25400DK-Mini to the distributor and ask for replacement?
Did you press the reset button on the CC Debugger after you connected it to the USB Dongle?
The USB dongle needs to be plugged into your computer for power.
You will also have to install the USB driver for the dongle. That should be found in the C:\Texas Instruments\BLE-CC254x-1.2\Accessories\Drivers folder of the BLE Stack.
If the above fail, then you may indeed have a defective USB Dongle.
