Warning Message in ble_app_uart building like wchar_t length mismatch

[prasath]

Hi After building ble_app_uart in Nordic SDK with board pca10028 it gives some warning like

/usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/bin/ld: warning: /usr/lib/gcc/arm-none-eabi/4.9.3/../../../arm-none-eabi/lib/armv6-m/libc_nano.a(lib_a-nano-msizer.o) uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail

Try to remove "nano.specs" the LDFLAGS in makefile

//LDFLAGS += --specs=nano.specs -lc -lnosys
LDFLAGS += -lc -lnosys
