- Thu Sep 08, 2016 10:54 am #54685 hi guys, i am new to programming.

I did find a code on github https://github.com/l740416/ESP8266-WifiSniffer/blob/master/ESP8266-Arduino-WifiSniffer.ino to see mac addresses and I am trying to save it on a SD card but the Arduino compiler says it ambiguous!

Code: Select allUsing library SPI at version 1.0 in folder: C:\Users\Ali\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.3.0\libraries\SPI
Using library SD at version 1.0.5 in folder: C:\Users\Ali\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.3.0\libraries\SD
Using library ESP8266WiFi at version 1.0 in folder: C:\Users\Ali\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.3.0\libraries\ESP8266WiFi
exit status 1
call of overloaded 'println(uint8 [36])' is ambiguous


Can Anyone help me to understand it why and help me out?
