LAUNCHXL-CC26X2R1: Advertising Name and Device Name are not reflected by changes made to project_zero.c

oldViking

Part Number: LAUNCHXL-CC26X2R1
Other Parts Discussed in Thread: UNIFLASH, CC2540

Hi, I am currently working on Task 4, Bluetooth low energy 5 Fundamentals, in CCS project ble5_project_zero_cc26x2r1lp_app.

Per the tutorial's directions I have modified 2 variables ( attDeviceName[], and advertData[] ) , in project_zero.c

Please see the attached file. The letters OR have been added to each of the strings.

Clean / build then proceeds smoothly. The project is then flashed into the development board using the CCS debugger. This also seems to go correctly.

After cycling power on the development board, I launch BTool, scan, connect, find UUIDs, and then read the values.

The value of the Device Name still reads "Project Zero"

What am I missing here ?

Thank you

Roy

Hello Roy,

I made the same changes to my project_zero.c and as you can see in the images below the adverData and the DeviceName were updated.

Hopefully this helps.

Hi David, Please see the attached screen shot of my BTool after performing a scan. I still do not see the changes I made to attDeviceName[] or advertData[].

Thank you for your help.

Hi David, After having given this more thought, it appears as though the flashing process is not going correctly, even though I get all of the indications from the debugger that it is.

I am not using the OAD. When using the debugger to flash the modified application software, is there something else that needs to be done with the project zero library or the bim_offchip ?

Is there some way to confirm that the flashing has completed OK and that all has gone well ?

Thanks

Roy

Hi Roy,

You could try with uniflash (devi.ti.com) and see if you get the same behavior. Also you could attach your image and I'll try on my side.

Best regards,

David

Hi David,

Per your suggestion I downloaded and installed uniflash V4. Seems to be a real good tool. It easily recognized my Launchpad and flashed my application image. Unfortunately, I still only see "Project Zero" in the advertising name and the DeviceName. I tried flashing both the .out file and the .hex

Then I erased all program memory, reflashed the .out, and the BIM. Still not the desired outcome.

Thank you for your time.

Hello Roy,

Could you please trying my ble5_project_zero_cc26x2r1lp_app_FlashROM_Debug.hex? And let me know if you see the same behavior.

Removed attachment as it did not include the BIM

Thanks,

David

Hi David,

Using Uniflash I erased the entire memory of my CC2650X2R1 ( at least I think so )

Used the debugger in CCS to program the bim_offchip.

Using Uniflash programmed the out file you sent me.

In BLE Device Monitor (V2.1.0) I see:

The advertising packet shows ProjectZero

The Device Name is Project Zero

This is quite bewildering !

My BTool (V1.41.05), and BLEDM are both hosted on a CC2540 Dongle.

Is there some sort of cache with these tools that needs to be cleared ?

Thank you
Roy

Hi Roy,

Could you please do the following:

1. Using Uniflash erase the entire memory.
2. Using Uniflash program the .out file that I sent you.

For this test do not program the BIM and let me know your results.

Thanks,

David

Hi David,

I did precisely as you directed.

Now I see no advertising packets at all using BLE Device Monitor.
My Launchpad seems to be mute.

Hi Roy,

My apologies, it looks like I uploaded the wrong file. Please try this one instead ble5_project_zero_cc26x2r1lp_app_plus_BIM_FlashROM_Debug.hex.

Best regards,

David

Hi David,

After using Uniflash to erase the entire memory, and program the attached .hex file, we have success !

BLE Device Monitor shows "OR ProjectZero" in the advertising data.

If I connect, and read the Device Name attribute, the value shows "OR ProjectZero".

So the question becomes, why can't I do the same thing with my project zero ?

Thank you

Roy

Hi Roy,

In your BIM, please make sure to define NO_COPY in cc26x2r1lp_bim_offchip_Release_unsecure.opt (make sure that you clean and rebuild your project. Also please see the note below "In case an imaged is flashed via debugger and no external image check should be made, define NO_COPY"

Best regards,

David

Hi David,

I went into this .opt file and did find a line with a NO_COPY in it. Please see the attached file.

Is this correct ?

Thanks

Roy

Hi Roy,

Change -DxNO_COPY to -DNO_COPY and hopefully that will do the trick.

Best regards,

David

Hi David,

I made the change that you wanted to my .opt file in the BIM project. see attached

Used uniflash to erase my Launchpad.

Cleaned / built my BIM, then flashed .out with uniflash

Cleaned / built my project zero, then flashed .hex with uniflash

Cycled the Launchpad power.

Using BLE Device Monitor, I see only ProjectZero in Both the advertising packets, and the Device Name. OR is missing.

Thank you

Roy

Hi Roy,

My apologies, I ran into this issue sometime ago and I forgot that you will also need to define the -DJTAG_DEBUG in your defines file (opt).

Finally this should do the trick and thank you so much for your patience.

Best regards,

David

Hi David,

That last change to the .opt file did the trick. I can now read my own advertising data and Device Name. If not for your help, I would never have figured out

that problem.

Many Thanks

Roy
