Welcome to this new forum section on Bluetooth low energy.   Please use this forum for discussions and technical support on Texas Instrument’s Bluetooth low energy solution.

 

CC2540DK-mini kit

Our CC2540DK-mini kit will allow you to setup and run Bluetooth low energy demonstrations easily and quickly.   You will find a user guides, quick start guides, reference designs, software and tools at

http://focus.ti.com/docs/toolsw/folders/print/cc2540dk-mini.html

 

The kit contains

CC2540 USB Dongle:  This is the device that will be acting as the BLE Master. It connects to a Windows PC’s USB port, and is pre-loaded with the master demo application software.

CC2540 “Keyfob”:  This is the device that will be acting as the BLE Slave. The PCB sits inside a plastic case, and can be removed with a small Philips screwdriver. It operates on a single CR2032 coin cell battery, and contains a two-colored LED, a buzzer, an accelerometer, and two buttons.

CC Debugger with mini USB cable, converter board, and a 10-pin connector cables: This is used to flash the software onto both the USB dongle as well as the keyfob. It also can be used for debugging software using IAR Embedded Workbench

    OK - 

    Posting, because my CC2540DK-MINI, doesn't seem to recognize / program either device. Tried tech support, they brushed me off saying the matter was technical, and sent me here.

    Installed all software, device driver, double checked all connections / power. Smart RF Flash programmer software recognizes debugger, but does not see either device when attached.  Debugger always shows red light, not green.

    So, did I get a dud? No help, nothing works. This isn't my first dev kit - I'm an experienced developer.

    Any help would be appreciated - need to get something going.

    Not sure what might be wrong. Lets check some things, and if nothing helps we may have to get you a replacement.

    - Do you get red light on usb dongle?

    - Is the red on the small ribbon connected to pin 1 on each device?

    - It looks like you are using the mini-kit debugger so you should have correct firmware, but you can check that it is 8 or above. Sec 5.31 of users guide.

    - A low battery on keyfob can cause this, but usb dongle should work with power from computer.

    As stated in the original post:

    - Yes, the dongle consistently has a red light.

    - Yes, the cables were double checked, are connected correctly, as pictured in directions, and oriented with pin 1 connected to the marked line, both ends.

    - The battery is brand-new out of the box. The master dongle is powered by USB when attempting.

    I have not checked the version of firmware, but it was as shipped on Thursday.. I can check the firmware,  but guessing that isn't it.

    I just received mine, and all went well - just like quick start.

    It soubd like you are doing most things right.  I would doubt both CC2540 boards are bad.  It could be cable issue or CCdebugger/cable/or driver.

    What versions of Windows?  I am running corporate XP SP3 here.   

    Does it recognize the CC2540 at all when you try operations on CCdebugger flash window/SOC operations?

    Did you get the latest smartRF Flash Programmer? (I had old and had to deinstall before installing latest Flash Programmer)

    On  the cables, mine works, but the connectors are 180 out - cable loops toward debugger instead of straight out, but is keyed on that end.  If you are going by red strip position, you should be OK that matches pin 1.    I know I had a CC2510 mini kit and consistently did it wrong and had to reverse the ribbon and it came to life.

    The red stripe should be near the S on Instruments on the CCdebugger as shown in quick start and outboard/away from USB plug on the dongle and nearest the battery on the FOB.

    Double check that the CCDebugger is recognized nicely in the Computer-.Hardware Devices in case there is a driver snafu and the firmware version of debugger just in case.

    To answer these questions, please read my previous posts.

    For specifics, XP SP3 patched current. Using fresh install, latest of all smartRF tools, including Fla

    again: Debugger recognized, firmware id 05CC, rev 0013.

    cables: checked, and rechecked. and now checked about 5 more times.

     

    Please, I need to get this running.

    I currently suspect a dead debugger, since it has *never* shown green, once.

    Thanks for your time, and help.

    Well, I was sitting here resetting the adapter .. with the cables in the same position they had been in.. 

    and suddenly the green light came on, and the debugger worked. Programmed both units with the given flash files which verified.

    I didn't move a cable, switch a supply, reinstall software.. nothing. Just pressed the reset button on the debugger... slowly.. repeatedly.

    Got me as to why this would work. I didn't change a thing.

    Debugger is now working, hopefully. We'll see how long this lasts...

    Mine was red for a long time too when suddenly it went green.  I happened to notice a message just disappearing about how a device driver had been found.

    Hello every body,

    what I did with my kit : 

    Test1:

    I download the last version of TI BLE stack (1.2) and BTool software from TI website
    I flash the CC2540 USB dongle using CC Debugger (green LED) with hex file "CC2540_USBdongle_HostTestRelease_All.hex"
    I flash the CC2540 keyfob module using CC Debugger (green LED) with hex file "CC2540_keyfob_SimpleBLEPeripheral.hex"

    Observations:
    A. The red led of the USB dongle switch OFF just after flashing complete
    B. After launching the BTool software, It didn't detect the COM port

    Test2:
    I flash the USB dongle and the Keyfob module with the first version of TI BLE stack.

    Observations:
    A. The red led of the USB dongle switch ON just after flashing complete
    B. The BLE Demo (Proximity) detect the USB dongle and the application works without any problem
    C. BTool detect the COM port and I can scan and detect the keyfob module (but I have a problem with connection).


    So what I would like to solve is the first problem, why TI BLE stack 1.2 does not work ??
