CC2540: how can I use it..?

Part Number: CC2540
Other Parts Discussed in Thread: BLE-STACK

Hi, I am a student in south korea.

I buy CC2540, and I want to use it. 

I connected it to Arduino, and I want to controll it using AT command.

Although I make circuit and upload programming, I cannot get any signal from Arduino.

I think the reason of this problem is that I am not bootloader this chip. 

So, I want to bootloader CC2540 using Arduino, can I?

I don't wanna CCdebuger because I use just chip not PCB board.

How can I solve this problem?

    Hi Minsu,
    You will need to flash the BLE-Stack to the chip, so you will need a CC Debugger. However, it will be better to migrate to CC2640R2 or even CC2642. They come on launchpads with integrated debuggers.

    Thank you for your answer.

    I am making my own bluno nano(using CC2540), so I cannot use CC2640R2 and CC2642.

    I looking for how to CC2540 bootload. There are a lot of information about that but I don't want to use CC2540 dongle or another module.

    I just want to bootload the 'chip'.

    How can I..?

    Hi Minsu,
    If the CC2540 is straight from the production distribution, it does not contain a bootloader. Initial software/firmware needs to be flashed to the device.

    If the CC2540 was already populated on a board, maybe a vendor has already pre-programmed it. If that's the case, you should reach out to the vendor directly.
