A2DP sink device appears only on specific devices #759

All associated library files have been updated to the latest version (as of Dec 13, 2025). audio-tools: 1.2.1 audio-driver: 0.2.0 ESP32-A2DP: 1.8.8 ESP32 board library: v3.3.3 Board: ESP32-A1S (ESP32 AudioKit) Problem: The module does not appear at all on any other devices (phones, laptops, computers, etc.) other than the one that has seen the device before and has connected to it then. I can connect freely to this device using that phone, but I can't even see it on any other devices. The device in question is a Honeywell CT40 PDA, and only that can see and connect to this module after programming. Please refer to the attached archive (WIP) for the code: p.s. I apologize for any of my past actions. I have overreacted. |

Not sure what scenario your are talking about, but I assume you try to use the ESP32 as A2DP Sink. Be careful with auto reconnect. If you are already connected to the last device, other devices will not see your A2DP sink any more! |

Try to reproduce the issue with the most simple sketch to make sure that you did not introduce the issue yourself.
