# warning: "sprintf_P" redefined

Hi,
Is the following IDE warning of any concern - could it cause issues?:

In file included from C:\Users...\Arduino\libraries\RF24Network/RF24Network.h:20:0,
** from C:\Users..._Teensy_110518.ino:13:**
C:\Users...\Arduino\libraries\RF24Network/RF24Network_config.h:88:0: warning: "sprintf_P" redefined
** #define sprintf_P sprintf **

It seems to cause no issues, but I'm wondering if that will always remain so.
If I can safely ignore it then that's what I'd rather do as tricking around with libraries I don't yet fully comprehend is something I'd rather leave for now...

Yes, you can ignore the warnings.
