pc_ble_driver_py.exceptions.NordicSemiException: No ping response after opening COM port

[shohidur]

Hi, 

I was trying to run dfu mesh example according to this. I attempted quite few times but every time having an error at step 11.

infocenter.nordicsemi.com/index.jsp

Here is my environment details:

OS: windows 10

nrfutil version: 3.5.1

mesh SDK: Mesh_v2.1.1_src

Board : nrf52832 

SDK version: 15

SoftDeive s132_6.0.0

step 1: Creating my own private key 

 nrfutil.exe keys generate private.pem

Step2: Generated respective public key in hex format

nrfutil.exe keys display --key pk format code .\private.pem --out_file dfu_public_key.c

step 3: Added this key in the end of  "bootloader_config_default.json" file.

Step 4: Creating own signed image  package for dfu

nrfutil.exe pkg generate --hw-version 52 --application-version 4 --sd-req 0x00A8 --application C:\nordic_semi\nrf5_SDK_for_Mesh_v2.
1.1\bin\blinky\blinky_nrf52832_xxAA_s132_6.0.0.hex --key-file .\private.pem secure_dfu_mesh.zip

Step 5:  Generating device page with provided script as follow

python .\device_page_generator.py  -d nrf52832_xxAA -sd "s132_6.0.0"

Step 6:  flashing soft device:

nrfjprog --program C:\nordic_semi\nrf5_SDK_for_Mesh_v2.1.1\bin\softdevice\s132_nrf52_6.0.0_softdevice.hex --chiperase

step 7: Flash the serial bootloader on all devices:

nrfjprog --program C:\nordic_semi\nrf5_SDK_for_Mesh_v2.1.1\bin\bootloader\gccarmemb\mesh_bootloader_serial_gccarmemb_nrf52832_xxAA.hex

step 8: flashing application:

nrfjprog --program C:\nordic_semi\nrf5_SDK_for_Mesh_v2.1.1\examples\dfu\build\dfu_nrf52832_xxAA_s132_6.0.0_Debug\dfu_nrf52832_xxAA_s13
2_6.0.0.hex

Step 9: Flashing device page:

nrfjprog --program C:\nordic_semi\nrf5_SDK_for_Mesh_v2.1.1\tools\dfu\bin\device_page_nrf52832_xxAA_s132_6.0.0.hex

Step 10: Resetting 

nrfjprog --reset

Step 11: Problematic one(Transfer the DFU archive over serial with nrfutil) 

 nrfutil.exe dfu serial -pkg .\secure_dfu_mesh.zip -p COM15 -b 1200

 I have problem only on step 11

Hi.

Could you check our which version of nrfutil you are using? 

Just run "nrfutil.exe version" in cmd.

The dfu quick start guide requires the version 0.3.0.0, which is found in this GitHub link.

version is 3.5.1, so i am thinking that i used wrong version. Now my question is how can i use the version you mentioned.
Thanks for your reply

[shohidur]

Hi,

I copied your provided files under mentioned directory and replaced existing file. But still i am not getting other options as you mentioned. If you need further details for reproducing the problem, i can send you the screen shot of my details installation. 

[AndreasF]

Hi.

Can you do all the installation steps one more time, that is, steps 1 to 6.

After you have finished, could you compare the files you now have installed, that is nrfutilmesh-script.py and nrfutilmesh.exe to the two files I've sent you, by running the command in cmd:

FC [pathname1] [pathname2]

Where [pathname1] is the path to the file you installed, and [pathname2] is the path to the file i sent you. And please post the result.

-- Andreas

[shohidur]

OK, i will get back to you once i am done

[AndreasF]

Hi.

Could you also post your PATH variables and which nrfutilmesh?

Just run the two command echo %PATH% and which nrfutilmesh in cmd and post the result.

- Andreas

[shohidur]

PS C:\Users\Shohidur> fc.exe /b C:\Python27\Scripts\nrfutilmesh-script.py C:\nrfutilmesh_by_nordic\nrfutilmesh-script.py
>$null
PS C:\Users\Shohidur> if (!$?) {
>> "The files are different"
>> }
The files are different

Same result for other file that you sent

[AndreasF]

Hi.

There could be problems in your PATH that might cause the issue, since you have multiple instances of different variables, and a odd number of  " also.

I've tried to clean a bit up in your PATH. Could you first change you PATH to this:

C:\WINDOWS;C:\WINDOWS\system32;C:\WINDOWS\System32\OpenSSH\;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files\CMake\bin;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\nodejs\;C:\Program Files\PuTTY\;C:\ProgramData\Oracle\Java\javapath;C:\Python27\;C:\Python27\Scripts;%PYTHON_HOME%";C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\GnuWin32\bin\make;C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin\;C:\Program Files (x86)\Skype\Phone\;C:\Users\Shohidur\AppData\Local\Microsoft\WindowsApps;C:\Users\Shohidur\AppData\Roaming\npm;

Then see if you get the -m and --mesh option from the command:

nrfutilmesh dfu serial --help

If you still dont get the -m and --mesh options I please follow these steps in this order:

1. Delete all nrfutil files you have in :C\Python27

2. Download this zip file called pc-nrfutil-mesh_dfu.zip.

3. Unzip the zip file.

4. Run the command: pip install --upgrade pip

5. Run the command: pip install --upgrade setuptools

6. Run the command: pip install -r requirements.txt

7. Run the command: pip install http://sourceforge.net/projects/py2exe/files/latest/download?source=files

8. Download and install VC compiler for Python.

9. Run the command python setup.py install while you are inside the pc-nrfutil-mesh_dfu folder.

10. Run the command python setup.py py2exe while you are inside the pc-nrfutil-mesh_dfu folder.

Hello,
Now i am having this error:

command : nrfutil dfu serial -pkg dfu_test.zip -p COM6 -b 115200 -fc --mesh

Upgrading target on COM6 with DFU package C:\nordic_semi\nrf5_SDK_for_Mesh_v2.1.1\dfu_test\dfu_test.zip. Flow control is enabled.
[------------------------------------] 0%

Failed to upgrade target. Error is: ord() expected string of length 1, but int found

Possible causes:
- bootloader, SoftDevice or application on target does not match the requirements in the DFU package.
- baud rate or flow control is not the same as in the target bootloader.
- target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.

Thanks, finally it worked. The problem was with my DFU package. Which i created with different nrfutil. Now everything is good. Thanks for your kind support.
