Out of the box the MCU runs a person counter programmer called PAXCOUNTER. Which uses bluetooth and WiFi transmissions to detect how many people are nearby.

And produces this serial output at 115200 baud on its micro-USB connector.

Which while interesting is of no use to this RF sniffer project.
To use the Arduino IDE for this MCU you need to add https://dl.espressif.com/dl/package_esp32_index.json into the “Additional Board Manager URLs” field in the File -> Preferences screen.
Then install/download the 32MByte esp32 board support package by Espressif in the Board Manager (see https://github.com/espressif/arduino-esp32)
(See https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/)
After this you can select the "TTGO LoRa32-OLED v2.1.6" board via Tools -> Board
In passing, I had to follow http://playground.arduino.cc/Linux/All#Permission to get serial monitor access
No good couldn't compile without getting below error. I also tried using board "Heltec WiFi LoRa 32" as stated in:
https://github.com/LilyGO/ESP32-Paxcounter/blob/master/platformio.ini
Traceback (most recent call last):

ImportError: No module named serial

That fized above arduino serial issue and can now program MCU with blink, WiFiscan, etc. sketches :)
So tried using PlatformIO Core (CLI) (I'm on a 32-bit Mint Linux laptop so VSC, etc won't install!)
Wouldn't compile.. missing bt_xxx.h file.
