Hi again.
Unfortunately, I’m not familiar with that board.
Maybe those methods are not supported in that particular board.
Maybe it only support BLE methods and not Bluetooth Classic, but I’m not certain.

Sara

Hi, I have an Arduino Nano ESP32 (from Arduino) and I’m trying to get the Serial Bluetooth to work in it and I’ve tried many examples from the web and there seems to eb a problem with the BluetoothSerial library (by Henry Abrahamsen, v.1.1.0) because it always gives me an error and I can’t load the sketches to the ESP32. The first error comes from the line:
BluetoothSerial SerialBT;
Compilation error: no matching function for call to ‘BluetoothSerial::BluetoothSerial()’
Any help would be appreciated!

In reply to Hector. My feedback from the ESP32 is also (-127.00C -196.60F), can you help me? How did you fix this problem?

Hi.
I thank you so much for the information here, I tested and it worked very well.
Now I have a problem, I explain: I have the esp32 working with dual core, core 0 will communicate through uart1 with a GPS board, and core 1 will communicate throuht bluetooth, but when the bluetooth works there is not communication with the GPS, and when there is such communication with the GPS then the bluetooth does not work. what could it be the problem here?.

I thank you so much for your help in advance.

Greetings

I uploaded the code to the ESP32 and it all was successful. I then tried to connect using the recommended Serial Bluetooth Terminal but I don’t see the ESP32test. It doesn’t show in the list. I am using Pixel 8 pro with Android 14. Any idea why it doesn’t show up?
