Double channel lora Gateway (UP/DOWN)
-
Hello everybody,
I m student and I am currently working on my final project. One issu that I encounter right now is that I have to make a two way radio communicaiton lora gateway (that does not have any relation with a LoraWAN platforms) it is just for private communication.
My question is how to make SPI connections between one RPi 3 (Master) and two RFM95W Lora transceivers (one for uplink and one for downlink) ?
Is it just making simple SPI connections with two slaves, or is there any other consideration to take into account ?Help please
Thanks

@riro2 Are you going to use MySensors library at all?
I would find many sources on internet how to connect a RFM95 module to a RPI. In fact, I have made a few PCBs for my Raspberry Pi 3 but this is all for TTN, which is using LoraWAN.https://github.com/hallard/RPI-Lora-Gateway

I'm experementing with this Library / Project:
http://cpham.perso.univ-pau.fr/LORA/RPIgateway.html
https://github.com/CongducPham/LowCostLoRaGw
based on the Libelium Libraries.
It is LORA-only (no LARAWAN). Thanks to the used arduPi-Libs there are the same soures for Arduino and Raspi.
Originally only sensors are supported. I have changed the sources a bit to support both directions but with ONE Lora module. It shouldn't be difficult to use two modules.

@xander I cannot help you with that. I have no knowledge of Liberium libs and never tinkered with Lora.

@alexsh1 Sorry you missunderstood. My post was only a hint to help riro2 with his LORA problem. The Libraries from the refered project are working fine for me. Thanks anyway!

@xander Yes, you are right - sorry about that. This is what happens when reading from the phone.
