UART and NRF_LOG simultaneously

Where did you attach them?

The only .c files I can find in the rar file is main.c, new_calendar.c and system_nrf52.c

I have attached all files app_mpu.c, nrf_drv_mpu_spi.c, nrf_drv_mpu_twi.c, sdk_config.h and nrf_delay.c which u mentioned...

I think problem is something else

Thanks for the project. The project integrated nicely with the SDK, but there seems to be some custom files missing:
app_mpu.c, nrf_drv_mpu_spi.c, nrf_drv_mpu_twi.c, sdk_config.h and nrf_delay.c

Are you able to share the modified files also?

Best regards
Torbjørn

I have uploaded my code....

I want to take mpu data and get char from user and that time I want to start time with the help of nrf_calendar.

Could you zip the project and include it here?
Then I can try to reproduce the issue.

It could be that the printf is somehow giving you issues, and you want to replace all the printf's with NRF_LOG_INFO.

Best regards

thanks Jakub,

but our problem is when we initialize uart the code stuck there. is there any solution for this? As in ble_app_uart example, where NRF_LOG and UART both works simultaneously, in my project I want to send mpu data on phone and get message by user through uart service.

In SDK14.2 you can try to use Logger module with CLI backend. In such case you can either print logs on UART or collect characters from it.

More about it:
