Bluetooth library source code?

[StridingDragon]

I've been running into some issues with BLE where packets arrive garbled very frequently and I was trying to look into the Bluetooth stack used in the ESP32. However, I can only find libbt.a as a library and no source code for it.

Can someone please point me towards the source code for the Bluetooth implementation and the GATT handler, etc.?

bluetooth library is closed source.
