Windows 11: Bluetooth Serial connects then immediately disconnects

[horace99]

using Arduino IDE 2.3.4 ESP32 core 3.3.2 running Bluetooth Classic example SerialToSerialBT serial monitor displays

Code: Select all

The device with name "ESP32-BT-Slave" is started.
Now you can pair it with Bluetooth!

Android phone connects OK and transfers data using Bluetooth terminal app

However, attempting to connect using Windows 11 "Add a device" it displays Connected for a fraction of a second then Not Connected - two virtual COM ports appears in Device Manager but attempts to connect to them using teraterm fail


Windows 10 connects to SerialToSerialBT without problems and teraterm terminal emulator communicates with COM port OK
