Arduino ESP32-Wroom-32D to XBee Via BlueTooth - arduino

Question

I have a few questions as to why my input isn't behaving correctly. I have 2 functioning scripts I've used:
ESP32 to Xbee using UART2, I open a serial connection to Xbee3 and type "+++" or AT Commands "ATID" and I am able to view to xbee's response via serial monitoring, works fine
Samsung Phone Serial App to ESP32 using Bluetooth, I'm also able to connect to the phone and type commands from phone to terminal and terminal to phone, works fine.
code for item 1:
//Arduino IDE
//ESP32 to Xbee UART2
//Select your modem:
#define TINY_GSM_MODEM_XBEE
// Set serial for debug console (to the Serial Monitor, speed 115200)
#define SerialMon Serial
// Set serial for AT commands (to the module)
// Use Hardware Serial on Mega, Leonardo, Micro
HardwareSerial SerialAT(2);
#define TINY_GSM_DEBUG SerialMon
void setup() {
// put your setup code here, to run once:
// Set console baud rate
SerialMon.begin(115200);
SerialAT.begin(9600);
delay(1000);
SerialAT.print("+++"); while (SerialAT.available()) {SerialMon.write(SerialAT.read());}
delay(1000);
}
void loop() {
// put your main code here, to run repeatedly:
// Access AT commands from Serial Monitor
SerialMon.println(F("***********************************************************"));
SerialMon.println(F(" You can now send AT commands"));
SerialMon.println(F(" Enter \"AT\" (without quotes), and you should see \"OK\""));
SerialMon.println(F(" If it doesn't work, select \"Both NL & CR\" in Serial Monitor"));
SerialMon.println(F("***********************************************************"));
while(true) {
if (SerialAT.available()) {
delay(1000);
SerialAT.println("ATID");
SerialMon.write(SerialAT.read());
}
if (SerialMon.available()) {
SerialAT.write(SerialMon.read());
}
delay(0);
}
}
Code for item 2:
//This example code is in the Public Domain (or CC0 licensed, at your option.)
//By Evandro Copercini - 2018
//
//This example creates a bridge between Serial and Classical Bluetooth (SPP)
//and also demonstrate that SerialBT have the same functionalities of a normal Serial
#include "BluetoothSerial.h"
#if !defined(CONFIG_BT_ENABLED) || !defined(CONFIG_BLUEDROID_ENABLED)
#error Bluetooth is not enabled! Please run `make menuconfig` to and enable it
#endif
BluetoothSerial SerialBT;
#define TINY_GSM_MODEM_XBEE
#define SerialMon Serial
HardwareSerial SerialAT(2);
#define TINY_GSM_DEBUG SerialMon
void setup() {
SerialMon.begin(115200);
SerialAT.begin(9600);
SerialBT.begin("ESP32testBLMfalse"); //Bluetooth device name
Serial.println("The device started, now you can pair it with bluetooth!");
}
void loop() {
// Access AT commands from Serial Monitor
if (Serial.available()) {
SerialBT.write(Serial.read());
}
if (SerialBT.available()) {
Serial.write(SerialBT.read());
}
delay(1000);
}
My issue was when I tried to combine these. See, I wanted to know if it was possible to open a Bluetooth connection with the ESP32 and send the AT commands from the phone app to the XBEE connected to it on UART2. This is what I'm currently doing. The command looks like it sends fine, but my serial output on reads:
"
The device started, now you can pair it with bluetooth!
10:44:04.546-> OK????????????????????????????????????????????????????????????????????????????????????
"
not sure if it's due to the bit rate, let me know if anyone can assist.
Thank you

}

if (SerialBT.available()) {
delay(1000);
Serial.write(SerialAT.read()); //send phone input to xbee
}
if (SerialMon.available()) {
SerialAT.write(SerialBT.read()); //send xbee output to phone
SerialAT.write(SerialMon.read()); //send xbee output to serial monitor
}
delay(1000);
}
I was expecting
Samsung phone [input] --BlueTooth--> ESP32 --UART2-> Xbee
Xbee [output] --UART2--> ESP32 serial monitor --BLueTooth-->Samsung phone
