How to modify or remove the WWAN profile which I created ?

Question

I created a WWAN profile using the Metro App sample, "Mobile broadband account provisioning sample".

When clicking the Submit button, it shows "Device was successfully configured".

A new profile was created at the folder ,C:\ProgramData\Microsoft\WwanSvc\Profiles.

It was OK.

But when I tried to modify the profile, the sample application shows a execption.

I want to modify <ConnectionMode> tag from auto to manual.

When I developed MobileBroadband device app for Windows 7, I need to remove profile

using API.

I suppose I need to remove the profile..

Are there any method for remove or modify the profile?

I need to modify it from Metro Style App.

Please advice !

Answer 2

I may find the reason why it happen.

It happens when I add <ConnectionMode>manual</ConnectionMode> or <ConnectionMode>auto</ConnectionMode> before <Context>.

It shows "Unexpected exception occured, error number:0x82170002".

If I did not add <ConnectionMode> tag, it show "Device was successfully configured".

For example, I could change APN.

I guess, new function, ProvisionFromXmlDocumentAsync() does not accept the <ConnectionMode> tag.

But I want to create "manual" mode profile.

What should I do ?

Any update?

There is no ConnectionMode element in the Provisioning schema.  (See C:\windows\schemas\provisioning\provisioning_wwan_v1.xsd for more detail.)  The profiles start as auto-connect, and are subject to the user's control thereafter.  The user can change the profile to be auto or manual.

To modify the profile, submit a new provisioning XML with the desired updates.  To delete the profile, submit a new provisioning XML with an empty MBNProfiles element.

Hi Mike,

Thank you for the information.

I can remove WWAN profile which I created.

I can remove WLAN profile using an empty WLANProfiles element, too.

I found a small problem.

If there is a WLAN profile which Wan-Ui created, I cannot remove directly.

I need to update the wlan profile before removing, then I can remove using empty element.

Is this a limitation ?

Answer 6

Yes, that's correct.  The app has control over profiles that the app created, and can remove them if needed at a later time; profiles that the user created are not intended to be under the app's control, and should only be removed by the user.
