Problem with adding uart to print

[Newbie]

Hello, I am using sdk12.2.2 and pca10040. I want to add uart drivers in ble_app_template code so that I can use printf to get my data on terminal. Unfortunately I am not getting anything on uart. I added app_fifo.c and app_uart_fifo .c and I have also added paths. My sdk config file is sdk_config1.txt

and my main file is main2.txt

Thanks,

Hi Newbie! I will start working on a solution for you. However, your sdk_confing.txt file appears to be empty. Also, you do not need to copy the content to a text file, you can just upload the .c or .h files directly.

Hi Joakim, I am sorry for the carelessness. I have uploaded the modified sdk.config and main file.

Hi Newbie!

I'm sorry for the delayed response.
I made some modifications to the the ble_app_template in SDK 12.2, to show you how I have done it. I will also add my sdk_config file. In the config file, make sure the following is added and enabled;
Drivers: UART_ENABLED. Libraries: APP_FIFO_ENABLED, APP_UART_ENABLED and RETARGET_ENABLED.
Make sure that you have the app_uart_fifo.c, app_fifo.c and retarget.c files added under nRF_Libraries in your project.

I hope that helps, and make sure to let me know if you have any questions.

main.c
sdk_config.h

Best regards,
Joakim
