Hi, i'm using STLink V2 for compiling the code, the weaknes of this compiler is you can't see the result debuging or serial print output.
so i'm using USB TTL to see output of the code, first i'm create some project to comunicate Serial UART so i can show the result on Serial Debugar (Arduino IDE serial Monitor or PUTTY)
and it's done,
my next problem is i want to colaborate this code with Gazell code in sdk12.3 using nrf51822, but i got this error
.\_build\nrf51422_xxac.axf: Error: L6218E: Undefined symbol app_uart_init (referred from main.o).
please help me, my code is
