Hi everyone, Im a newbie and i want to sent a package use LoRa.
i just buy a arduino uno r3 and dragino lora shield v 1.4.
But when i try to test by example code (rf95_client,Lora_simple_client_arduino,...). It not work.
Serial monitor always show me "init failed".
What happen? Is my shield broken?Or i need to config the shield? if i need to config, can u help me how to config that shield. I think my frequency is 433 MHz
Thanks for reading.
