ESP8266 connection to LLCC68 always fails, the hardware used is E220-400T30D.

First of all, thanks to the author for creating this library and for the convenience it gives us.

I had some unexpected errors and problems while using the lora library created by the library owner for development board configuration, and would like to get some explanations and suggestions from the library owner about the problems.

1、When I was configuring the development board with the esp8266_e22_setConfiguration example in the LORA library, I got some errors, see the appendix for the errors
2、Similarly, when I configured the development board with the esp8266_e22_04_SendFixedTransmission example in the LORA library, I got a similar error, see the appendix for the error
3、Some doubts about the esp8266_e22_setConfiguration example program, see Appendix
4、Some doubts about the esp8266_e22_04_SendFixedTransmission example program, see Appendix
