* Author - Marcel Schulz (alias Schullebernd)
* *************************************************************
* See further library details on https://github.com/Schullebernd/SBNetwork
* *************************************************************
* This example is a client with a BME280 temperatur, humidity and barometer sensor on I2C.
* It sends the measured values every 20 seconds to the master.
* To setup the master device for this example, open the UniversalSensorMaster example and run it on a second device.
* **************************************************************
* Step 1 - Prepare your device like in the example sketch GettingStartedClient
*
* Step 2 - Connect the BME280 sensor to your arduino/wemos device
* Connect Arduino --> BME280
* A4 --> SDA
* A5 --> SCL
* 3V3 --> VCC
* GND --> GND
* empty --> CSB
* empty --> SD0
* The I2C Address of BME280 usually is 0x76 --> Put this into bme.begin(0x76) at setup function. If this is not working try 0x77.
*
* Step 3 - Download and include the Sparkfun BME280 library.
* https://github.com/sparkfun/SparkFun_BME280_Arduino_Library
*
* Step 4 - Run the project
* Open the file SBNetwork_config.h in the library folder ../libraries/SBNetwork/src/SBNetwork_config.h and comment out (put two // at the line start) the line 6.
* Line 6 should now look like this //#define RUN_AS_MASTER
* Connect the Arduino via USB to the PC, select the right board and COM interface in the tools menu and run the project.

* 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 39 "SBNetwork networkDevice(D2, D8);" to the correct pinout for an Arduino (6,7).
* To get shure, that the SBNetwork library is build for a Master-Device open the SBNetwork_config.h in the libraries folder and get shure that line 6 is not commented out.
* #define RUN_AS_MASTER
* **************************************************************
* 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
* Open the file SBNetwork_config.h in the library folder ../libraries/SBNetwork/src/SBNetwork_config.h and comment out (put two // at the line start) the line 6.
* Line 6 should now look like this //#define RUN_AS_MASTER
* 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.
