i need to make ios swift app that receive data from esp32 that use "bluetoothserial.h"

[digerati73]

#include "BluetoothSerial.h"

BluetoothSerial SerialBT;
bool isconnected = false;

void Bt_Status (esp_spp_cb_event_t event, esp_spp_cb_param_t *param) { if (event == ESP_SPP_SRV_OPEN_EVT) { Serial.println ("Bluetooth: Connected"); isconnected = true; } else if (event == ESP_SPP_CLOSE_EVT ) { Serial.println ("Bluetooth: Disconnected"); isconnected = false; } }

void setup() { Serial.begin(115200);
while (!Serial);
Serial.print("\n"); Serial.println("dbg> ESP32 Test program. Start ...");

SerialBT.register_callback (Bt_Status);
Serial.println("The device started, now you can pair it with bluetooth!"); if(!SerialBT.begin("ESP32")){
Serial.println("An error occurred initializing Bluetooth"); }else{ Serial.println("Bluetooth initialized. Bluetooth Started!"); Serial.println("Bluetooth device name(ESP32), Ready to pair..."); } }

void loop() {
if (Serial.available()){
char command = Serial.read();
Serial.print("Recived command : "); Serial.print(command); Serial.print(", ");

if(command == '3'){
Serial.println("REQ#3:");
cmd_tx_result_data1(); //test1: make string & TX data: swing raw data, bluetooth
} else{
Serial.println("Wrong command(3)");
Serial.println("Usage: ");
Serial.println(" REQ#3: make string & TX data"); }

}

}

void cmd_tx_result_data1() {
String tx_data1 = "here is some format code";
if (isconnected) {
Serial.print("dbg> tx_data1 = "); Serial.println(tx_data1); SerialBT.print(tx_data1);
} else { Serial.println ("dbg> Bluetooth: Client Not Connected"); }

}

i need to receive data from above esp32 code at ios app coded by swift or swiftUI
but i failed...

i found this "react-native-bluetooth-serial" project.

can i receive data from above esp32 code using "react-native-bluetooth-serial" program ?
