implementation UART to examples from SDK

[František]

Hello, 

I have problem with implementing UART to simple_coap_client example, but there is too much problems. Some issues have been solved, but it still is not all. 

defines in sdk_config.h  -solved 

uart0 - used by openthread lib -solved

Can you help me with best way to use COAP and UART in same project?  

nRF5_SDK_for_Thread_and_Zigbee_2.0.0_29775ac

Linux ubuntu 18.04

Segger studio

defines in sdk_config.h  -solved 

uart0 - used by openthread lib -solved

 

Can you please describe what the issue is? What is your progress?

Best regards,

Edvin

when I compile project simple_coap_client from SDK 

-added uart switches to sdk_config

-added include directories and c files to project

-disable uart 0 enable uart 1

multiple definition of `UARTE0_UART0_IRQHandler'

../../../../../../external/openthread/lib/gcc/libopenthread-nrf52840-sdk.a(libopenthread_nrf52840_sdk_a-uart.o): In function `UARTE0_UART0_IRQHandler':

I think should be exist guide how to add UART to example project because  it is important but so complicated

[Edvin]

Your compiler output should also tell you something like:

previous definition here: <path to other place it is defined>.

How did you "Disable uart 0 enable uart 1"?

It looks like you still have enabled uart 0 somewhere in your project. Maybe in sdk_config.h?

this defines was copied from sdk_config of project peripherals/serial_uartes and I disable uart0
