Target not run as the symbol "main" is not defined

But then....

Why my mobile phone can not detect my Bluetooth device? It detects other Bluetooth devices which are positioned nearby.

Hi,

 Is the information below what you saw? I just ran the same project on my setup using CCS and it works out of box. 

Yes! Output is identical.
But I do not see my device when I search from mobile phone for Bluetooth devices.

What did you modify on your project? Does your phone detect the device when you just download the sample project without modification?

In my project I started to modify pin inputs and output (according to my project needs). I did not modify anything in "BluetoothStack" part.

Also, I downloaded (unmodified) SimpleBLEPeripheral and SimpleBLEPeripheralStack to my hardware. And I still do not see my Bluetooth device when I search from my mobile phone

Do you have sensortag app or LightBlue app? If not, try to download any of them and see if you can find your device from those apps.

I downloaded unmodified SensorTag and SensorTagStack to my hardware. I know that sensor part will not work, but Bluetooth part shal work... Right?

But I still do not see my device when I search for it from my mobile phone.

Hi,

Sorry for not being clear. What I meant was downloading those 2 apps to your phone and keep simpleBLEperipheral project in your device. Search BLE devices thru those 2 apps. you should be able to find it thru sensortag app

I did as you suggested:
a) start SimpleBLEPeripheral at my device
b) download and start BLE SensorTag application at my mobile phone

And I still do not see my device.
I even changed hardware (I have 2 of those) and there is a same situation - device in not visible. So, I think it is not a hardware problem.

I know that my colleague managed to start Bluetooth application on this hardware. But he works on different location. Is it possible to download his HEX file into my board? (And what are exact steps to do it?)

Do you already have the HEX file?

If yes, then you can program the hex file to CC2640 from flash programmer 2, which you can download from here:

If not, and your colleague is using IAR, modifying on top of TI example project (ex: SimpleBLEPeripheral), then you can find the hex file inside the following folder:

C:\ti\simplelink\ble_cc26xx_2_01_00_44423\Projects\ble\SimpleBLEPeripheral\CC26xx\IAR\Application\CC2640\FlashROM\Exe

If you are using CCS, right click on Application, and choose properties.

make sure the you have the following command in your Post-build steps, which should be there by default

"${CG_TOOL_HEX}" -order MS --memwidth=8 --romwidth=8 --intel -o "${ProjName}.hex" "${ProjName}.out"

Then you can find your hex files in your CCS workspace.

In CCS, the hex files are split into stack and application. remember to program both images.

\workspace_v2.1\SimpleBLEPeripheral\FlashROM\SimpleBLEPeripheral.hex

\workspace_v2.1\SimpleBLEPeripheralStack\FlashROM\SimpleBLEPeripheralStack.hex

Finally, I managed to find download HEX file.
Thank you for support!

Glad to hear it worked out :)
