Below is the C++ code on ESP32 that will be receiving the text. It is looking for a { curly brace character as the starting character. See line 41.
If I user the AsyncStreams and send bytes, the text is not transmitted in the clear as I understand it so the receiving code is not seeing the curly brace character.
What am I missing here?
Thank you in advance for helping!
