multiple definition of `UARTE0_UART0_IRQHandler'

[tinytrex]

I have a bunch of nRF52810 kit. I am creating a BLE central device which would dicover and conenct to one or more BLE peripherals. I am using nRF SDK 15.3.0 and it has an example for BLE peripheral device for nRF52810 which uses S112. However, It doesn't really has an example code for BLE central device meant for nRF52810 using S112. I am trying to port/modify an existing BLE central example (nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_uart_c\pca10040\s132\ses) which originally was written for nRF52832 and uses S132 to nRF52810 using S112. I have made the necessary changes in the project configuration but I see the following error whenever I try to build the code:

1> C:/Program Files/SEGGER/SEGGER Embedded Studio for ARM 4.16/gcc/arm-none-eabi/bin/ld: Output/ble_app_uart_c_pca10040_s112 Release/Obj/nrfx_uarte.o: in function `UARTE0_UART0_IRQHandler':

I am attaching the project configuration file for your refrence.

Hi,

Uploading the project file gives no details on your configuration. Please zip the entire example directory and upload it.

I would recommend that you compare your configurations in the sdk_config.h file with the one found in pca10040e project for ble_app_uart (peripheral) example for the following and sub-configs: 

• UART_ENABLED
• NRFX_UART_ENABLED
• NRFX_UARTE_ENABLED

Best regards,
Jørgen

Dear Jørgen, I have zipped everything and atatched here. The path to the example is: nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_uart_c\pca10040\s132\ses

nRF5_SDK_15.3.0_59ac345.7z

There are two ways to solve this issue.

1. Disable legacy UART peripheral support. This is done by setting '#define UART_LEGACY_SUPPORT 0' in your sdk_config.h file.
2. Enable peripheral resource sharing for UART and UARTE. This is done by setting '#define NRFX_PRS_ENABLED 1' and '#define NRFX_PRS_BOX_2_ENABLED 1' in your sdk_config.h file.

Thank you Jørgen. This seems to solve the build issue. However, I wanted to understand how do I enable NRF_LOGS becasue I am unable to see NRF_LOGS (INFO/DEBUG etc):

#ifndef NRF_LOG_ENABLED
#define NRF_LOG_ENABLED 1
#endif

#ifndef NRF_LOG_DEFAULT_LEVEL
#define NRF_LOG_DEFAULT_LEVEL 3
#endif

The ble_app_uart_c example has log enabled with RTT backend only by default, as UART is used together with the NUS service. Did you try opening RTT Viewer, and did you see any logs there?
