I’m interested in using the conduit to receive Lora messages from a device that does not use the LoraWAN protocol.
I’ll need develop software to read the radio output directly (in place of, or altering, the lora gateway software)
So where does the radio appear – is it a USB or SPI device in /dev?
I’m trying to do a proof-of-concept in python – I have pip installed on mlinuix, then tried to install spidev but no luck, probably because of lack of gcc on the conduit.
Cheers for any pointers,
Jon Ross

Our current MTAC-LORA card has a USB interface.

Here is the gateway branch used for the gateway library in mLinux, it will show how to access the card
http://git.multitech.net/cgi-bin/cgit.cgi/lora_gateway.git/log/?h=1.7.0-mts

Otherwise the built in packet forwarder can be used accessed through UDP, lorawan is not required to receive and send packets through the radio.

Recipes for building the packet forwarder:

Documentation for communicating with packet forwarder:
