So I stumbled upon this thread while having similar problem, but with HC-05 module. So because I have too much free time on my hands during finals (no I don't) I decided to create a small github repo that might help someone sometime. https://github.com/Sackhorn/HC-05-Pro-Micro-Hookup

The code is:

void setup()

  pinMode(9, OUTPUT);  
  digitalWrite(9, HIGH); 
  Serial.begin(9600);
  Serial1.begin(38400);
}

void loop()
{
  
  //Serial1 is the physical Serial Connections on TX and RX pins
  if (Serial1.available()) Serial.write(Serial1.read());

  // Serial is from my understanding the virtual connection with computer via USB 
  if (Serial.available()) Serial1.write(Serial.read());
