hi @Harish-kumar , we released here Lora-Mesh, that I thought it will help you.
Well, mesh-network over LoRa, has a specific protocol (Thread), and probably it's not implemented neither in Arduino, nor Multitech.
This would work if all 3 devices would be Lopys, the last one (gateway) would be registering itself to TTN as gateway, and forwarding data from the first Lora (sensor), thru the second one (the repeater, which does this automatically, being a Mesh node - router role).
I am using Lopy, I am new to this. I need to send some data to cloud via Lorawan instead of using wifi. Is it possible ? If it is , can anyone say me the procedures ?
First check whether LoRaWAN is good for your application, it depends on the volume of data you are transmitting, what is the latency your application can accept, etc. Provide details. If it fits to your use case from networking view we can discuss how to implement.
