The BT keyboard stops working after entering some chars

[lismarc]

I have small "Bluetooth Keyboard 3.0" from Chinese TECLAST tablet.

This keyboard works great with many laptops and desktops.
I'm able to pair the keyboard with ESP32, however always stops working after entering few chars (~around 20 keys pressing) or less than one minute from running ESP.

Final effect is I can not enter chars or sometimes the last chars is repeated continuously even turn off the keyboard.

Tried many modifications of code I've found in the net, but the problem still exists.

My setup:

• Hardware:
  ** board ESP32 DEVKITV1,
• Software:
  ** IDE Arduino 1.8.19,
  ** Board Manager: Espressif Systems 1.0.1 (with 1.0.4 same effect),
  ** Board: ESP32 Wrover Module,
  ** Partition scheme: Huge App (3MB, No OTA/1MB SPIFFS),
• Configuration:
  ** #define VIDEO_STANDARD NTSC
  ** #define EMULATOR EMU_ATARI

I was able to dump the log from serial port:

Some idea what is wrong and can be improved?

What is the status of this fancy project? Any plans? Some development?
