BLE on ESP32

[san27deep]

What are the security protocols used in BLE connection establishement and data transfer? Is it secure channel or not? If not, is there any provision to do so?
if it is, where can i find the security implementation?

I doubt they've implemented much of any of the security (Or, rather "Security" being that it's an easy thing with an Ubertooth to circumvent pretty much 80% or more of all "implementations" by jamming the data connection, followed by a key invalidation.)- you can check in the bluetooth component of the IDF- source code's there for the upper level from the HCI level up on the stack.
