UART implementation in light_switch_client code

[Sachin]

I want to interface Client Sensor over UART in light_switch_client code. Can you please give me the idea,how to do it.

I am using Mesh_V4.0 and SDK 16.0

1.OK in that case I have to change the pins in default uart_init() function or I need to write separate uart_init() function for new pins ? can you please specify which four pins I shall use ?

2.I understand ble_app_uart_coexist doesn't have functionality to provision the device using nRF BLE mesh application so how I suppose to add the device in the same group to which server device is added ?

Basically I want to take data from sensor and then want to publish it over mesh from the client (I suppose ble_app_uart_coexist has client  functionality ) to server.

Hi Mttrinh,

I am waiting for your reply.

Hi,Could you please look into my doubt

1. Like I mentioned in the previous reply, you can use any other GPIO pins. Have a look at the Pin assignments section in the the Product Specification for the nRF52832. Then you configure the UART peripheral to use those pins, change the pins in the default uart_init() function.

2. Yes, that is correct. The example doesn't have support for GATT provisioning so you can't use the nRF Mesh app to provision. You need to use our static provisioner in the SDK to provision. You can find it in the Light switch example.

1.Hi I have changed the RX_PIN_NUMBER (8---->19) and TX_PIN_NUMBER(6----->20) in uart_init() function and connected these connections to my sensor and short GROUND too.Now when I run and start to debug the code I am receiving NRF_BREAKPOINT_COND in app_error_weak.c

2.Also uart_event_handle function will get called if sensor is sending the data OR I need to write anything for that

Thanks
