Hello,
I'm unable use the library which I downloaded from the repository
here. I'm using Arduino Mega 2560 with LoRa E22-900T30S and i followed the guidelines given in this
link and developed the circuit according to the first Arduino circuit mentioned.
I tried using pins 4 and 5 of arduino mega 2560 initially but i got an error message saying "No response from device! (Check wiring)" even though my circuit was exact same as that of the one present in the link i mentioned above. Then I changed to Software serial and made connections accordingly invoking my uart 1 by Serial2 in arduino code but still got the same message saying "No response from device! (Check wiring)". Then finally I chose to try in Hardware serial setup and used same Uart, following lines is how my serial monitor is printing messages now
