Hello everyone!

Can you please advise me why AsyncElegantOTA does not work in parallel with the BluetoothSerial ? To use AsyncElegantOTA service I must end BluetoothSerial and vice versa.

The only way I found and works for me is here. My real code is more complicated, but I’ll simplify it like this:

#include <Arduino.h>
#include <WiFi.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>
#include <AsyncElegantOTA.h>
#include <BluetoothSerial.h>

AsyncWebServer server(80);
BluetoothSerial SerialBT;

bool ota_need;  // "we just need OTA service" flag
bool bt_need;   // "we just need BT service" flag
bool ota_is_up; // "OTA service up" flag
bool bt_is_up;  // "BT service up" flag
void setupService();

void setup() {
    Serial.begin(115200);
    SerialBT.begin("ESP32");
    bt_is_up = true;
    bt_need = true;

    // Wifi connect code here
    // ...

    // server.begin()   // not yet
    ota_is_up = false;
    ota_need = false;

    AsyncElegantOTA.begin(&server);
}


void loop() {
    // other code here

    setupService();    // setup service based on currrent needs

    // other code here
}

// ---------------------------------------------------------
// Up or down OTA / BT services, based on current needs
// ---------------------------------------------------------
void setupService() {
    // ota_need = TRUEORFALSE;  // both changed somewhere in code
    // bt_need  = TRUEORFALSE;  //

    // OTA need?
    if ( ota_need ) {
        // BT down:
        if (bt_is_up) {
            SerialBT.end(); // end BluetoothSerial
            delay(1000);    // or other way of "BT down" verification
            bt_is_up = false;
        }
        // Server up:
        if (!ota_is_up) {
            server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
                request->send(200, "text/plain", "Hi! I am ESP32."); });
            server.begin(); // start AsyncElegantOTA service
            ota_is_up = true;
            Serial.println("HTTP server goes up");
        }
        // else Serial.println("HTTP server already up");
    }
    // BT need?
    if ( bt_need ) {
        // Server down:
        if (ota_is_up) {
            server.end();   // end AsyncWebServer
            delay(1000);    // or other way of "server down" verification
            ota_is_up = false;
        }
        // BT up:
        if (!bt_is_up) {
            SerialBT.begin("ESP32");    // start BluetoothSerial
            bt_is_up = true;
            Serial.println("SerialBT server goes up");
        }
        // else Serial.println("SerialBT server already up");
    }
}
