Approach to use nrf24_sniffer on ESP32 platform (without WIFI)

--------------------------------------------------------------

Original work : http://yveaux.blogspot.nl/2014/07/nrf24l01-sniffer-part-1.html

PULL GPIO15 LOW (no verbose startup info after DTR reset) !!!

-----------------------------------------------------------

This project is a modification of original Yveaux work to adapt ESP32 devkit1 board & nrf24L01 laying around as packet sniffer. Changing platform required some code work to Arduino part and to Windows "pipe driver" part.

Developed in VSCode+Platformio / VSCommunity.

1. Requirements:

• ESP32 based board, eg. ESP32 DevKitV1 or Lolin/NodeMCU...
• nRF24L01+ board
• WireShark 1.10.8 (old, old version... newest - 3.2 doesn't work with these plugins)
• PC with Windows

2. Wired connections : ESP32 nRF24 GND 1 VCC (3v3) 2 22 CE 3 5 CSN 4 18 SCK 5
   23 MOSI 6 19 MISO 7 21 IRQ 8

3. Usage:

• compile arduino source with VSCode+Platformio (ESP32 platform + Arduino library installed)
• flash into ESP32 board
• install WireShark, copy into Program Files\Wireshark\plugins files from Wireshark dir (only one !! of mysensors.dll)
• run Nrf24Sniff.exe -h to see help text

Add pipe connection in Wireshark [\\.\pipe\wireshark] and go.
