I am using the Adafruit HUZZAH32 Feather with the Arduino IDE.
It seems that when it comes to reading BLE Characteristic data we are currently limited to:
std::string getValue(); //which reads string data only uint8_t* getData(); //which reads an unsigned single byte only
uint8_t* = pBLEchannel->getData();
After much testing it appears as though the sending of anything other than a single byte (float, double, record data) has to be sent as a string and then decoded again at the ESP32 end after a string read.
Is this actually the case or is there some way of reading the raw data values (multiple byte) from ->getData()?
