Node with ESP8266 and RFM95W

This can mean two things

1. you defined your code to use a RFM95W/SX1276 while a RFM92W/SX1272 is connected.. to change this, in your .ino change the below line (change into SX1276):
   #define CFG_sx1272_radio 1

2. your wiring is incorrect, or module just not working
