nrf52-mesh-light-switch-client-server-proxy-master add uart module

[Enzo]

HI

I use SDK nrf52-mesh-light-switch-client-server-proxy-master with nrf52840 PDK。

I need uart module，so I add include path，c file to the project.

add header file ， uart_init function and uart event handle dunction to main.c . 

set SDKconfig.h as uart example of SDK15.0.0 .

At beginning，it works fine. But when I send many data or send data Very frequently, it will stop running and show this error:

app_error_weak.c,  105, Mesh error 1 at 0x00000000 (:0)

after debug, i fuond that uart_event_handle function came a event of APP_UART_COMMUNICATION_ERROR.

Hi

I got something new.

I tried to modify FIFO BUFFER SIZE RX and TX to a maximum of 2048. I found that if sent and received 5 bytes per 200 ms. There will be no mistakes. But more than 5 bytes will make a mistake.
In addition, I tried to modify the priority parameter in the function uart_init() to be high priority. There was no error every 200 ms when the test received and sent 20 bytes. The question now is whether changing priorities will have any other impact.

 APP_IRQ_PRIORITY_LOWEST-->APP_IRQ_PRIORITY_HIGH
