WiFi_Kit_series | Arduino source codes and toolchain for WiFi_Kit_series

I am new to the esp32 and LoRa messaging.

I am following the two examples in the heltect esp32 lora library.

The two modules I am using to send and receive data have an oled display... and I print their values to the serial monitor. The data values appear on the oled display but they are random characters in the serial monitor like this... "⸮⸮3⸮⸮JS⸮⸮⸮⸮⸮J)⸮⸮".

My question is how can I receive data from the sender in string/float/integer like form so I can perform logic on them. I am new to c++ and lora so any help is welcome.

I am pretty sure this(the first code block directly below this paragraph) is the piece of code responsible for printing the received message, but it is not printing in any type of format I can work with even when I change the "char" dtype to String.
