How to handle the DFU in 51822 SDK

[Alice]

Hi,

I want to know how to do the OTA,so I refer to the device_firmware_updates project in SDK.Now I can use the command

line to program the bootloader.hex to 51822(The chip has no application).Then I refer to ble_dfu_send_hex project and I have downloaded the setup as "readme" say.But my computer cann't support .Net Framework 4.5 and IntelHex v1.5 cann't be installed sucessfully(see the attachment).I donn't know why,could u give me some advice?The systerm is WIN XP 32.Could I do the DFU on my computer?

Besides,I have read the "Chm SDK documentation",but I still don't know how to handle the DFU in SDK. Are there any detailed document about how to handle the DFU in SDK? Thanks.

Look forward to your reply.Thank you very much.

Best regards, Alice

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.
