Hello, I am using ESP32 to send data via serial Bluetooth to a PC. The data is in the form of 4 byte C++ integers at a rate of 250 samples per second. However, the current approach of sending each data entry as a char byte is very slow and not enough to transfer the data.
Could anyone refer a library to send data using serial as fast as possible? Furthermore, is there any way to send the values as integers instead of sending each digit as a separate character byte?
