Dear Sir,
I use nrf5_SDK_for_Mesh_v2.0.1_src.zip and test proxy server project,
I scanned the device nRF5x Mesh Light (0x1827 Service), I click "Discover services", but the Service discovery aborted, connection terminated.
What is correct procedure to use proxy server? I expect that I can control the LED On/Off by MCP.
Thanks & kind regards

Hello Kwan,
Sorry for the late reply.
The proxy examples are still in experimental mode, so there are some bugs.
Can you try to comment out the lines from 693 to 702 in mesh_gatt.c? You should see the service 0x1828, (not 0x1827) and the characteristics 0x2ade and 0x2add.
However, I can't guarantee that the application is bug free from there on. There are a lot of comments in the mesh_gatt.c file. Take a look at them, and maybe you can see if you are able to control the lights when working a bit with this file.
Best regards,
Edvin
Hello Edvin,
Any timeline to fix the bug, our customer plan to launch the product at Oct 2018, I need to finish the BLE Mesh in Aug 2018
or
Any suggestion for me, if I need to control it by mobile phone with BLE Mesh?
Thanks & kind regards

Have you tried to comment out the lines that I suggested? Are you able to detect the services then?
Also, may I suggest that you try to use nRF Connect for Desktop? It is the "new" version of MCP. MCP is currently deprecated.
Best regards,
Edvin
Hello Edvin,
I download nRF Connect for Desktop and launch " Bluetooth Low Energy" App, after I select COM port (PCA10028 old version no mbed include), Error found in Log: "Failed to get device info:Error occured when get device info. Errorcode: CouldNotCallFunction(0x9)....".
I read the "nRFConnect_BLE_User_Guide_v2.1.pdf", but I don't find answer to fix the problem. Would you let me know what can I do?
Thanks & kind regards

Can you try to erase the board using nRFGo Studio or "nrfjprog -e" in cmd with the command line tools before opening nRF Connect?

Hello,
I would like to clarify, I found the service is 0x1827 and characteristics are 0x2adb and 0x2adc, but you said it should 0x1828?
Thanks & kind regards

Hello,
Ok. I believe you. I just saw in the proxy_server project that it used the UUID 0x1828. Maybe the proxy_client uses 0x1827, or that we have different versions.
If you want to use a phone to control the light_switch examples in the SDK for Mesh, I suggest that you look into the mesh library (currently only for iOS. I believe Android is on it's way). The mesh library is written for iOS, and available here on github.
Erasing the board was only because I thought that you were not able to communicate with the board that you used with nRF Connect.
What happens if you try to either enable the notification on 2ADC or try to write to 2ADB?

The app is available on app store (iOS) as well. Search for nRF Mesh. The link in the previous reply is for the source code for the app.

Hi Edvin,
I tested iOS nRF Connect App with mesh proxy_server application, and I send data 0x01,0x02,0x03, everything , the device will disconnect at write_evt_handle().
However, if I remove the disconnect function at write_evt_handle routine, send data sometime, it will jump to app_error_weak.c.
