How can I resolve BLE connection issues with ESP32 and Android 11 using ArduinoBLE?

Hi Devs, I’m using an ESP32 as a BLE peripheral device to broadcast sine values to my Android 11 phone via the nRF Connect app, i am using the ArduinoBLE library on the ESP32. However, I’m encountering a connection issue. After disconnecting, I get a ‘couldn’t connect’ error message when trying to reconnect. The only workaround I’ve found is to forget the device, scan for it again, and then connect. I’m getting the following error message in my serial monitor: `E (23456) BLE: Connection failed, status=0x008`. I’ve tried adjusting the BLE advertising interval and payload size, but the issue persists. I’d appreciate any advice on how to resolve this issue and establish a stable connection.
