@skoky what chip is your Dragino board based on? Could you share a photo of your setup and explain the wires you connected?

ive got same error with dragino v1.4

Hi,
was having trouble also with my v1.3. You will see that the Dragino hat wires NSS (SPI CE) out to pin 22 (a GPIO) and not to either CE0 (24) or CE1 (26). If you solder a jumper wire between pins 22 and 24 on the hat it should solve the issue I expect. Further info in:

hi is this board supported?

thanks

nevermind, i made it to work my lowering the SPI frequency from 12E6 to 10E6

var SPI_OPTIONS = {
mode: spi.MODE0,
maxSpeedHz: 10E6
};

[sandeepmistry]

Has anyone tried using the options to pass in the pins the board uses: https://github.com/sandeepmistry/node-sx127x/blob/master/API.md#create-device

I have modified these options but not solved the problem, have you got some suggestions ?
