nifeng:

Unzip to c:\
Open cmd.exe as admin
Type "cd c:\intelhex-1.5"
Type "ipy setup.py install"

If ipy is not a recognized command, add a variable named PATH with value C:\Program Files (x86)\IronPython 2.7\ to the Environment Variables.

Does this help? If not, please provide some more details on what the problem is.

Hi Petter: I also encountered the same problem and here https://devzone.nordicsemi.com/index.php/how-to-handle-the-dfu-in-51822-sdk. But I was Win 7 system. I downloaded intelhex-1.5tar.gz, intelhex-1.5.zip and intelhex-1.5.win32.exe three files. I run intelhex-1.5.win32.exe his tips: "No Python installation found in the registrg"

I read what you said, but I started to approach setup.py do not know how to install? I run the cmd.exe file but inside I do not know what to enter to install the file. I hope you can give me help?

You should be able to use the PCA10001 board for this method.

Hi Petter Myhre

Can I use this method for PCA10001 board ??

Hi,

I have done it and the OTA works fine now,but I use the other way,I donn't use the command:ipy.exe E:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\experimental\ble_dfu_send_hex\main.py -f C:\NewFirmware\ble_app_hrs.hex -n DfuTarg -a A67864586912,it indicates "cann't not load MasterEmulator.dll".

I do as follow:

erase chip, program "s110_nrf51822_5.2.1_softdevice.hex"
program "bootloader" using nrjprog
"DfuTarg" can be found in Master Control Panel.Right-click "DfuTarg" then select
a "ble_app_proximity.hex"
after 100% done,the OTA is successful.

But I donn't know what is the difference between this way and you tell me before.Is there two ways to do the OTA?

I understand your frustration, this is still in an experimental face and has not been tested on XP.

I may have a fix for you; if you navigate to C:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\experimental\ble_dfu_send_hex\dfu and edit init.py

And change

masterApiBasePath=r'C:\Program Files (x86)\Nordic Semiconductor\Master Emulator'

masterApiBasePath=r'C:\Program Files\Nordic Semiconductor\Master Emulator'

Yes, I have done it as you said(see the attachment). It still indicates "cann't not load MasterEmulator.dll",but I can find two MasterEmulator.dll in my computer. The Dongle I use is 2.1 and Master Control Pannel version is 3.5.

I am very confusedand very frustrated about it.

Did you try this?

In cmd, navigate to C:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\experimental\ble_dfu_send_hex. Then run the command(the last 12 bytes should be your device address):

ipy main.py -f C:\NewFirmware\ble_app_hrs.hex -n DfuTarg -a CDB53D6D16B6

Hi Petter,

I have tried many times,but it still indicates "cann't not load MasterEmulator.dll",what problem may be do you think?Could you give some advice to try?Thank you very much.

Hi Petter,

Thank you very much for your strong support.Now I can run the ipy setup.py install

.But when I run the command:ipy.exe E:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\experimental\ble_dfu_send_hex\main.py -f C:\NewFirmware\ble_app_hrs.hex -n DfuTarg -a A67864586912,it indicates "cann't not load MasterEmulator.dll",but I can find two MasterEmulator.dll in my computer while the version is not the same.

I use the Dongle 2.1 and Master Control Pannel 3.5.

Could u give me some advice?

Hi Alice

I think I have a solution for you.

-First add the IronPython executable to the enviroment variables:
Right-click My Computer, and then click Properties. Click the Advanced tab. Click Environment variables. Under user variables: Click New and: Variable name: PATH Variable value: C:\Program Files\IronPython 2.7\

Then in cmd.exe, navigate to C:\interhex\intelhex-1.5 and try this command:

ipy setup.py install

Hopefully this will work. Sorry for the confusion, I had IronPython and intelhex in the same folder, making without the steps mentioned above.

I do as u say,it can run the install,but it indicates package direstory intelhex does not exist.I don't know why.

Is there any problem when you test it?

Petter Myhre — Wed, 23 Oct 2013 11:11:25 GMT

I see now that I had a typo in my previous post, it should have been C:\intelhex not C:\interhex. Try this command:

ipy.exe C:\interhex\intelhex-1.5\setup.py install

Or change the foldername to C:\intelhex and use this command:

ipy.exe C:\intelhex\intelhex-1.5\setup.py install

Regarding the .Net Framework, you can try an earlier version, like .NET Framework 4.

Hi Petter,

Thank you for your help.

I have tried it,but the command line still indicates "setup.py doesn't exist". I also try to unzip intelhex-1.5.tar,but the result is the same.

Could u help me do the test by using a 32-bit windows XP?I think many、many ohter customer will use windows XP and will meet the same problem as I said.

Besides,.Net Framework 4.5 cann't be installed successfully on my computer,will this have an impact on this issue?

From your picture, you should unzip intelhex-1.5. This is actually intelhex-1.5.zip, but it seems you have hidden known file extensions on your computer.

RE: How to handle the DFU in 51822 SDK

Petter Myhre — Wed, 23 Oct 2013 07:39:34 GMT

Hi Alice

Then you should change the command to:

ipy.exe C:\intelhex\intelhex-1.5\setup.py install

I'm not aware of any problems using a 32-bit windows XP.

Hi Petter,

Thank you very much for your detailed reply.

I have done 1 to 5 as u said and I can see the address advertising.But the IntelHex cann't be installed successfully by using command. I have downloaded three files frompypi.python.org/.../IntelHex and I have build the folder in C:(C:\intelhex).pls see the intelhex picture. u said "the zip should be used. Unzip to e.g. C:\interhex",But I donn't know which zip or file would be placed at C:\intelhex.

I have unzip intelhex-1.5 to C:\interhex,then use "ipy.exe C:\intelhex\setup.py install"command to install IntelHex,but the command line indicates "setup.py doesn't exist". However,I can find the setup.py file in C:\interhex\intelhex-1.5.

Besides,the PC is WIN XP 32,and is there any problem for this?

Petter Myhre — Tue, 22 Oct 2013 16:01:21 GMT

As Morten said, the zip should be used. Unzip to e.g. C:\

Open cmd.exe as administrator, navigate to the folder where you unzipped IntelHex(C:\intelhex-1.5), use the following command to install IntelHex:

ipy setup.py install

If ipy is not a recognized command, add a variable named PATH with value C:\Program Files (x86)\IronPython 2.7\ to the Environment Variables.

We are working on improving the SDK documentation, but I will try to explain how to apply DFU OTA(BLE).

Open nRFgo Studio, erase the flash and program the SoftDevice.
Open the bootloader project in C:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\bootloader using Keil, and load it using nrfjprog.exe(see SDK, DFU Flashing).
Open Master Control Panel, see that your device is advertising(DfuTarg), and remember its 12 byte device address.
Close Master Control Panel, the dongle needs to be available while updating.
Open the ble_app_hrs project, compile, and copy ble_app_hrs.hex found in C:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\ble\ble_app_hrs\arm_build to C:\NewFirmware\
In cmd, navigate to C:\Keil\ARM\Device\Nordic\nrf51822\Board\nrf6310\device_firmware_updates\experimental\ble_dfu_send_hex. Then run the command(the last 12 bytes should be your device address):

ipy main.py -f C:\NewFirmware\ble_app_hrs.hex -n DfuTarg -a CDB53D6D16B6

Open Master Control Panel, and see that your device is not adverising as Nordic_HRM.

Please let me know if anything is unclear or if you have any other questions.

Had the same problem. Use the zip, not the Windows installer. Worked for me.
