I have the same issue as @yijenlu1971 in https://github.com/sandeepmistry/arduino-LoRa/issues/170#issuecomment-406109594_

The sender doesn't send unless its connected to a computer via USB.

I am using the LoRa32u4 II (v.1.2) board on both ends.

Thanks,

Do you have an antenna attached to your LoRa module? If not, your USB cable's shielding will act as an antenna(a poor one..). If you have, then you might have put a incorrect antenna on your module.

Check if you don have any while(!Serial) if not the case you should change your power supply or as well as the antenna
