Hi have Raspberry Pi 3b.

I am trying to connect sx1278.

The radio module

I get the same error for the sender and reciver

node sender.js
open Error: Invalid version 0, expected 0x12

any Idea?

Hi
Module probably isn't connected properly or you don't enabled SPI interface in Raspberry Pi configuration (sudo raspi-config).

Also provide sufficient power to the LoRa Module as it draws good power, Better to provide external power supply 3.3V rather than feeding it from the raspberrypi's 3.3v.

Hey @sandeepmistry!

I'm also experiencing the same issue using the Dragino lora pi hat v 1.4 with a raspberry pi 3

I also tried modifying the pins used inside the library but had no better luck.

I managed to have the communication between the pi and the lora module working using this script https://github.com/tftelkamp/single_chan_pkt_fwd, So I don't think there is a power or a configuration issue.

Any other suggestion on how to solve this?
