LAUNCHXL-CC2650: How to keep a code running without physical connection?

Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2650,

Basically title.

For example, after I load Project Zero onto the CC2650 Launchpad, I want it to keep running after I disconnect it from my laptop.

I can keep the MCU on the board constantly powered but after disconnection it stops executing the code.

What is the correct procedure?

    Does the device work at all after just connecting power (without trying to debug the device)? You can take the software variable out the equation by loading a pre-build .hex file and see if it operates after connecting power.

    What is a pre-build .hex file and how do I load it?

    You can find prebuilt cc2650lp_simple_peripheral_rel.hex under C:\ti\simplelink\ble_sdk_2_02_01_18\examples\hex if you install BLE Stack v2.2.1. You can use Flash Programmer 2 to download cc2650lp_simple_peripheral_rel.hex to your LAUNCHXL-CC2650 to see if it works.

    Is there a way to generate a hex file from the source code?

    I don't really need the hex file of the project zero. I have a project of my own.

    Do you use CCS? or IAR?

    I am using CCS Cloud.

    Checking with CCS cloud, I can see hex file is output on debug folder and you can download it.

    I loaded the hex file (Project Zero for now) onto the MCU but I don't see the device in the BLE Scanner.

    Flash Programmer 2 gives me:

    Does the resetting at the end has something to do with the launchpad not transmitting?

    Do you also download ProjectZeroStack to your LAUNCHXL-CC2650?
