in the arduino gui... i include the library
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

that is at V2.0.9

I'm getting unexpected errors and would like to point to V2.0.3 which I can scroll down and find at
https://github.com/espressif/arduino-esp32 ...

turns out I cannot pass String into sprintf

so I had to add .c_str() to each String

sprintf(line5, "%s %s", IPString.c_str(), wifiMacString.c_str());

whats puzzling is why the compile wouldn't complain about that

I'm trying to display the mac address on the display... Ive had no trouble displaying anything else but it displays
mac: ?
I use the same String variable and output to the serial console with no issue

here is what displays in serial console
IP Address: 192.168.1.162
signal strength (RSSI):-53 dBm ...
