I am able to provision the device. But not able to get the composition data.

[Amrith]

Hi, I am trying the to create a mesh application using iOS nRFMESH SDK. I am able to provision the device but i am not able to get data from the getCompositionData method.

The MeshNetworkDelegate always returns to below method.

func meshNetworkManager(_ manager: MeshNetworkManager,

                            failedToSendMessage message: MeshMessage,

                            from localElement: Element, to destination: Address,

                            error: Error) { }

Not sure what error i have done. On high level i have checked for node.isCompositionDataReceived which in turn moves to getCompositionData which is always giving error in ConfigurationViewController.

Could you clarify, you can get the composition data when using the nRFToolbox or the sample app. But it didn't work when you implement the library in your app ? 

Note that after the provisioning is finished, the connection will be terminated and established again for the configuration (getting composition data). 

[Amrith]

Any update on how to fix this one??

[Hung Bui]

HI Amrith, 
I'm still waiting for the response from our app team. Could you tell which error is returned when you do getCompositionData ?

[Amrith]

Hi Hung bui, 

App is moving to Access Layer and later point to Network layer where the pduType is incorrect from the NetworkManager in send request, which in turn produces Request time out error.

Hi Amrith, 

Please get the log on the phone as it can provide information about what's going on. To enable logging, please follow the suggestion bellow: 

The sample app logs can be seen in the app called Console. This is standard logging tool on Mac.

If they use the library in their app, they need to set logger delegate to MeshNetworkManager and Bearers to get full logging. Then they need to print it or send to Console, like the sample app is doing.

https://github.com/NordicSemiconductor/IOS-nRF-Mesh-Library/blob/45e12224e8b5f2d45659e99dddda966b1ba17789/Example/nRFMeshProvision/AppDelegate.swift#L57

Also you can try capture a sniffer trace of the communication between the phone and the device. It can also give us some information.

How to open the bearer before getting the compositionData? Logs shows that bearer is closed. 

It first shows request timed out as bearer is closed. Later after some time, centralManager delegate is called in and bearer opens and sends the data to getCompositionData. But the message received doesnot come under any of the switch case in ConfigurationViewController MeshNetworkDelegate which should have been ConfigCompositionDataStatus.

in sample app - Once the provisioning method is called and provisioning is complete, bearer closes and again centralManager delegate is called along with its methods. But when sdk is used, it doesnot call the centralManager delegate which is only called in the viewDidAppear of the ConfigurationViewController.

As stated in the documentation (https://github.com/NordicSemiconductor/IOS-nRF-Mesh-Library/blob/master/Documentation/GETTING_STARTED.md#local-elements-and-models) you need to set your localElements in the manager. This can be set to an empty array (localElements = []) if you don't need it, but needs to be set. The setter initializes ConfigurationServer model, which is responsible for parsing the CompositionDataStatus message.
