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

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?

[František]

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

#ifndef NRFX_UARTE_ENABLED
#define NRFX_UARTE_ENABLED 1
#endif
// <o> NRFX_UARTE0_ENABLED - Enable UARTE0 instance
#ifndef NRFX_UARTE0_ENABLED
#define NRFX_UARTE0_ENABLED 0
#endif

// <o> NRFX_UARTE1_ENABLED - Enable UARTE1 instance
#ifndef NRFX_UARTE1_ENABLED
#define NRFX_UARTE1_ENABLED 0
#endif

...

#define NRFX_UART_ENABLED 1

#ifndef UART1_ENABLED
#define UART1_ENABLED 1
#endif

What compiler/IDE are you using? 

Can you send the project in a .zip folder? (ps: it may be too large to upload here. Just delete the build files, and zip it).

Best regards,

this is link to google drive zip file of SDK 

project is simple_coap_client

Hello,

Can you try to change the define in sdk_config.h:

#define NRFX_PRS_ENABLED 1

to

#define NRFX_PRS_ENABLED 0.

On my end, this makes the project compile, and I can still use the CLI. I don't know what you intend to use the other UART for, but can you try this and see if it works?

Best regards,

Edvin
