Debug-logging without using Serial.print and without WiFi In order to transmit text from the Arduino board to the HC-05 Bluetooth module, I have use Serial.print. However, I don't see a way to debug the code without using Serial.print to test the other features of the software. Is there another way to transmit text from the Arduino to the computer, and from the Arduino to the HC-05, simultaneously (and without WiFi)?
Yes, what version of Arduino are you using?


For Arduino Mega, you can use Serial.println for writing debug data and Serial1.println for communication with HC-05. (See Example: MultiSerial Example)
For other Arduino boards, you can use Serial.println for writing debug data and SoftwareSerial library for communication with HC-05. (See Example: SofwareSerial)
