/*  
 *  ------ LoRaWAN Code Example -------- 
 *  
 *  Explanation: This example shows how to configure the data rate.
 *  The possibilities are:
 *  
 *    LoRaWAN EU:
 *    
 *    0: SF = 12, BW = 125 kHz, BitRate = 250 bps
 *    1: SF = 11, BW = 125 kHz, BitRate = 440 bps
 *    2: SF = 10, BW = 125 kHz, BitRate = 980 bps
 *    3: SF =  9, BW = 125 kHz, BitRate = 1760 bps
 *    4: SF =  8, BW = 125 kHz, BitRate = 3125 bps
 *    5: SF =  7, BW = 125 kHz, BitRate = 5470 bps
 *  
 *    LoRaWAN US or AU:
 *    
 *    0: SF = 10, BW = 125 kHz, BitRate =   980 bps
 *    1: SF = 9,  BW = 125 kHz, BitRate =  1760 bps
 *    2: SF = 8,  BW = 125 kHz, BitRate =  3125 bps
 *    3: SF =  7, BW = 125 kHz, BitRate =  5470 bps
