* This Getting started is prepared for using it with a Wemos D1 mini as a master device.
* If you want to use an Arduino, then change the line 38 "SBNetwork networkDevice(false, D2, D8);" to the correct pinout for an Arduino "SBNetwork networkDevice(false, 6, 7);".
* **************************************************************
* Step 1 - Prepare your device
* Connect a nRF24L01 transmitter to a Wemos D1 mini or an Arduino Device
* WEMOS > RF24      ARDUINO > RF24      --------------------------------------
* ------------      --------------     |   GND #  # VCC          TOP VIEW     |
*   3V3 > VCC          VCC  > VCC      |    CE #  # CSN          of nRF24L01  |
*   GND > GND          GND  > GND      |   SCK #  # MOSI                      |
*    D2 > CE             6  > CE       |  MISO #  # IRQ                       |
*    D8 > CSN            7  > CSN      |                                      |
*    D7 > MOSI          11  > MOSI      --------------------------------------
*    D6 > MISO          12  > MISO
*    D5 > SCK           13  > SCK
*
* Step 2 - Build the sketch for the master device
* Connect the Wemos via USB to the PC, select the right board and COM interface in the tools menu and run the project.
* After building and loading up to the Wemos, the serial monitor should show some log data.
* 
* Step 3 - Now open the example sketch GettingStartedClient to build a client device
