Hi There,
I am trying to build an application that uses UART 0 (for debugging) and UART 1 (to read data over from a separate hardware). Simple objective is to send "Hello nrf_serial" on both UART and receive them at the other end. My code is given below and have attached it too. The issue that I am facing right now is, when I enable both UART, no data is received on both.
However, when only UART1 is enabled, I could receive data on UART 1. I enable and disable UART 0 and UART 1 using macros
Am I doing something wrong here?
Any help / pointer will be highly appreciated.
NOTE: I am using
nrf5_SDK_v15.0.0 and evaluation board with PCA10056.
Attached is main.c and sdk_config.h
Thanks,
Amol
