UART cann't receive data when using nRF5_SDK_12.1.0_0d23e2a in ble_app_multilink_central example

[Alice]

Hi,

I'm using the ble_app_multilink_central example in the newist SDK nRF5_SDK_12.1.0_0d23e2a, nRF52832. Now it can printf the log information. I want to use the uart to receive and send data from other MCU. So I add the app_uart_fifo.c document and add the uart_init() function according to the ble_app_uart example, but the uart cann't receive or send data.

Besides, before I add the uart_init function, the ble_app_multilink_central example can printf log information but I don't see any setting about the UART. I don't know why.

Thanks for your help

Hi Kristin,

I have enable NRF_LOG_ENABLED and I have added NRF_LOG_BAKEND_SERIAL_USES_RTT to the keil->Option for target->C/C++->Define to enable RTT, but the uart still cann't receive and send data. The log information can output correctly.

Hi, I am also facing same problem. What did you do for this? I am also not able to receive the data over UART. I also followed same procedure.

Lots of cases on devzone regarding rtt. e.g this or this.
