ARDUINO PRINTLN INT STRING HOW TO
This tutorial shows you how to initialize String objects. Serial.println("En attente de la connexion BLE. You can append characters to Strings, combine Strings through concatenation, get the length of a String, search and replace substrings, and more. Floats are similarly printed as ASCII digits, defaulting to two decimal places. TxCharacteristic.writeValue(To_App.c_str(), To_App.length()) Numbers are printed using an ASCII character for each digit. String To_App = String(Calc, 3) + "," + String(Q, 3) Serial.println("En attente de la connexion BLE.") }
