Update since last week. I've implemented logic to track the flight time of Bluetooth packets, but not happy with the chip's ability to assign timestamps to and process incoming packets, currently sitting at around 1ms which is enormous. I want to leverage the ESP32's dual-core design, and am attempting to offload the BT callback to a separate dedicated core. Single thread, multiple cores. First time messing around with tasks and semaphores. I can run the Bluetooth callback task successfully on the same core as the main loop but it crashes when ran on a separate core, probably from trying to access a null pointer. There's a lot of global variables that really should be cleaned up as well.
1ms for packet ingest is definitely not ideal. I'm really hoping I can cut that down and not have to switch to a more powerful chip.

We're starting over. I'm moving from Arduino IDE to ESP-IDF, for the following reasons:
It's been 5 months since I've touched this thing, and reassembling my pieces in a new format will help me warm up.
I'm really not happy with how the Arduino IDE locks you into a setup->loop structure. I'm not used to it, it's just a wrapper for what the ESP IDF already does, and a loop doesn't really work for this type of project
The work I've done so far isn't going in the trash, we're just moving all the puzzle pieces to a bigger table
In reality, this project would take another 5 month hiatus while I focused working on the final semester of my bachelor’s degree in Software Engineering, resuming the week after final exams end.
