nRF Mesh Client and Server combined

Question

Development Software: nRF5 SDK for Mesh v3.1.0 SEGGER Embedded Studio for ARM v3.50 SoftDevice S140 v6.1.0 Computer Platform: Windows 10 Professional Hardware: Two nRF52840 DK's What I'm trying to do: I'm trying to have a node act as both a client and a server. I've merged the Generic OnOff client and server examples, keeping the models separate, but merging the server main.c file and the client main.c file, similar to this example: https://github.com/NordicPlayground/nrf52-mesh-light-switch-client-server-proxy . I have modified both the client and server models to send and receive red, green, blue and brightness values, all stored as uint8_t. I've also modified the button_event_handler in main.c to send: R: 255, G: 0, B: 0, Br: 100 when button 1 is pressed R: 0, G: 255, B: 0, Br: 100 when button 2 is pressed Status Message, containing the state of RGB, Br in Server model, to verify the packets being sent are actually being saved to the server, when button 3 is pressed Node Reset when button 4 is pressed The program compiles, and flashes to the board, and I receive the following in my debug log: , main.c, 421, ----- BLE Mesh Light Switch Server Demo ----- , main.c, 399, Initializing and adding models , generic_rgb_server.c, 277, Status: 0, generic_rgb_server.c, 283, Status: 0, generic_rgb_server.c, 286, Status: 0, app_rgb.c, 284, Status: 0, app_rgb.c, 291, Status: 0, app_rgb.c, 294, Status: 0, main.c, 217, App RGB Model Handle: 2 , generic_rgb_client.c, 215, Status Code: 0, mesh_app_utils.c, 65, Device UUID (raw): 991945FCE7B5AA46935F152CCFD48D12 , mesh_app_utils.c, 70, Device UUID : FC451999-B5E7-46AA-935F-152CCFD48D12 The program seems to run and initialize just fine. If I load the program onto two different DK's, I get the log above, and they are discoverable when scanning from the nRF Mesh app for iOS. The problem is that when provisioning one DK from nRF Mesh, the provisioning process is stopped by a disconnect. The nRF Mesh app then tries to re connect and finish the provisioning process, which sometimes works, but sometimes doesn't. When it does work, the moment I try to provision the other board to create a 3 node network, the first one disconnects from the network, or vice versa. Can someone help me figure out why this is happening, and point out any flaws in my code, attached below: reng_device.zip If you have an existing nRF5 SDK for Mesh v3.1.0, extract the above directory and place it where the green reng_device text is below in your file hierarchy: nRF5 SDK for Mesh Root/examples/ reng_device The example I'm referring to is under ../reng_device/server/light_switch_server_nrf52840_xxAA_s140_6_1_0 I simply added client model code to the server and havent renamed anything.
