UART print is not getting?

[arun]

Hi all,

I'm using pca10040 board with sdk version nRF5_SDK_11.0.0-2.alpha_bc3f6a0.

There i'm using example code of spi handling. Instead of nrf_log_printf i changed printf and enabled uart_init(). Program is compiling successfully but i'm not able to get any prints in console. In uart_example code i can able to get prints in console.

Is there anything i need to change in Makefile or somewhere?

Hereby i attached my main.c file and Makefile.

Thanks in advance.main.c

Try to use app_uart_fifo.c instead of app_uart.c in your project. If you use app_uart.c printf will only print out the first byte.

Update 2016-04-07: This is also a bug if you use ble_app_template example in SDK 11, where app_uart.c is used instead of app_uart_fifo.c. This will be fixed for the next SDK release.

Thanks a lot, Now i got uart prints in console.

So I can not use nrf_log_printf in 11.0.0-2.alpha right. Because I use nrf_log_printf printf a String but just one char show up now.

Does this bug fix yet?

There have been no new SDK release yet, hence this bug is not fixed. The workaround is still to use app_uart_fifo.c instead of app_uart.c. With this workaround you should be able to use nrf_log_printf.

The problem was that ble_app_template used app_uart.c instead of app_uart_fifo.c by default. The nrf_log module is now using its own implementation for uart so it is fixed.
