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

Question

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:
ordic_semi
rf5_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:
ordic_semi
rf5_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:
ordic_semi
rf5_SDK_for_Mesh_v2.1.1\bin\bootloader\gccarmemb\mesh_bootloader_serial_gccarmemb_nrf52832_xxAA.hex 
 step 8: flashing application: 
 nrfjprog --program C:
ordic_semi
rf5_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:
ordic_semi
rf5_SDK_for_Mesh_v2.1.1	ools\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. 
 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
odejs\;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
rf5x\bin\;C:\Program Files (x86)\Skype\Phone\;C:\Users\Shohidur\AppData\Local\Microsoft\WindowsApps;C:\Users\Shohidur\AppData\Roaming
pm; 
 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 f ollow 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.
