UART and mesh

[Bilal]

Hi Team,

I am working on Mesh SDK 3.10, I have requirement of mesh with Ble Uart. So I decide to take this example "ble_app_uart_coesixt". I build this example without any error and burn it on development board. when I Nordic toolbox (UART), I see device and connect it. and everything is OK. But when i use BLE mesh app to provision this device, I am not getting device list while scanning by mesh app.

Please suggest me the best approach towards it. my requirement is to control BLE mesh by giving command using smart app.

Hi Bilal, 

The ble_app_uart_coexist doesn't have PB-GATT role supported (provisioning via BLE). The reason is quite obvious, it was made so that it will be ble_app_uart and mesh at the same time, not with proxy role. 

So there are two options: 

1. Provision the node using a provisioner via PB-ADV (like the provisioner in the light switch example, or the PyACI)

2. Either disable ble_app_uart at the beginning and enable the proxy role to do provisioning, or you can think of combining UART service and the PB-GATT service together. But this approach would need quite a lot of code modification and understanding of the code.

Hi Hung Bui,

Thanks for your reply,

Ok, if I use provisioner like used in light switch example. then what is the use of UART in coexist example?.

and second thing. if we do the code modification, will it work for my requirement?

What exactly is your requirement ? 

The purpose of the ble_app_uart_coexist example is to do a normal BLE application and mesh at the same time (not provisioning via a phone or working as a proxy node).

 My requirement is control a mesh network with smartphone app . a node have multi-function node like switch, PWM and position (52833) etc .

will uart coexits works in my case or not?

You can base your application on the light switch example. You can use the phone app to do provisioning and to turn off and on the light.
