Some questions for "nRF Mesh" apps and proxy client/server examples

[Jeffery]

Hi

I am trying "nRF Mesh" apps to provision and configure proxy client and proxy server node (SDK Mesh v2.2.0).

1. Have user manual or help information for "nRF Mesh" apps?

2. Did Nordic release Android source code of "nRF Mesh"? How about iOS version?

3. I tried connecting proxy client and server by nRF connect, and found Mesh proxy service (UUID:0x1828)

    but no Mesh provisioning service (UUID:0x1827).

    Why not use Mesh provisioning service in proxy client/server examples?

Mesh Provisioning Service: 

    Allows a Provisioning Client to provision a Provisioning Server to allow it to participate in the mesh network.

Mesh Proxy Service:           

    Enables a server to send and receive Proxy Protocol Data Units (PDUs) with a client.

Hi Bjørn

1. I watched the youtube video. But, the apps was NOT the same as the apps I downloaded fromm Google Play.

    The GUI was different. The apps version at my phone was v1.0. Please confirm it.

2. OK. I can find the apps source code in Github.

3. I read the explaination at infocenter. So, mesh provisioning service(UUID 0x1827) was active at provisioning stage. After provisioning was

    completed, apps disconnected  and reconnected device in order to do configuration. Correct?

    Then, mesh proxy service (UUID 0x1828) would replace mesh provisioning service (UUID 0x1827) to finish configuration.

Now, I can provision and configure PCA10040 which flashed SDK Mesh v2.2.0 proxy client and proxy server.

But, I also found some problems.

1.  If all the unprovisioned devices are proxy clients or proxy server sand power on, I can scan all devices at scanner panel of apps.

     Then, try to select one by one to provision and configure all. First device was done successfully.However, as I selected next unprovisioned

     device, apps ran "provision" automatically and didn't wait I click "provision" button. Message was shown " sending composition data...".

     Then, disconnect this device and cancel provisioning.

     But, if I close the apps when current device was provisioned successfully and reopen the apps, next unprovisioned device can also be

     provisioned successfully.

2.  Can  lighting client or server which didn't have GATT proxy feature also be provisioned and configured by apps via proxy nodes?

     I tried apps to scan unprovisioned lighting client and server when proxy nodes were connected and already provisioned.

     Apps cannot find these devices.

     In my opnion, I think it is more feasible that few proxy nodes exist at one mesh network.

     If all nodes in network have proxy feature, all nodes will broadcast connectable IND ADV packets. It will cause hevay noise for mesh

     network.

Hi Jeffery,

1) Yes, the Android app looks slightly different, but should have the same functionality as the iOS app.

3) Yes, I believe the app disconnects because the softdevice needs to reset. I do not fully remember the details of why this needs to happen, but the behavior you mention should be correct.

1) Could you please upload the debug log from nRF Mesh. I am not sure I fully understand. When you say: "Then, disconnect this device & cancel provisioning", did the nrf mesh app automatically disconnect from the device?

2) The main idea with the proxy nodes is to have few proxy nodes which can connect to regular BLE devices. Like you mention, it does not necessarily make sense to only have proxy nodes because not all nodes will have to connect to a regular BLE device. Take a look at this devzone case for more information.

Kind Regards,

Bjørn

Hi Bjørn

1. Can nRF Mesh apps  only support Generic ON/OFF model?

2. If customer want to support variety of models, like Generic Level, and Battery etc., can nRF Mesh apps

    identify these models and show the model type in screen? It's similar to nRF Connect or Master control panel

    to show service types after service discovery. 

[Bjørn Kvaale]

1) Yes, that is correct as of today.

2) This support may be available at a later date. If you send me a private message, I can put you in contact with your local regional sales manager. He may be able to help you further.

Hi Bjørn,

Is the above information still correct?

If yes, what would be the easiest way to check availabilty of other models (e.g. battery, properties)

Thank you,
Matevz
