I did quite a bit of reading on TTN about Gateways, Nodes, Applications, etc...
I think once I can muster up some more funds for an actual Gateway; I will convert this to a Node. This PyCom LoPy4 is really a learning experience for me. The idea of using MicroPython is all new to me.
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).
But besides that, the receiver must contains a lora_sock.recv(64) call, in order to get something. Please have a look at the simple examples in the documentation on how the code structure has to be set up.
Thank you for your reply, YES true that compute module does not have wifi or BT , so only we go with UART connection, and i have connected the fipy and RPI compute module via UART. But how shall ssh to RPI compute module and access the RPI file structure.
After the serial connection now i want to send data within the RPI compute module to server. How to do this??
I have currently set up a nano gateway and several nodes (with LoPy) on the 868MHz using the EU868. From what I understand, AS923 is supposed to be used, but there are no strict regulations on the frequencies around 868MHz as of today. It would be better to work on the 923MHz frequency, thus I am currently wondering if anyone has gotten any success on 923MHz, or AS923.
When I tried to replicate the EU868 to the AS923, I couldn't get the TTN to display any values other than a random value to pop up only once. I was wondering if anyone with success or failures can share their experience.
@gnm I set up the Raspberry because I found it hard to connect to Eduroam wifi at my university. Setting up my own Wifi hotspot was therefore much easier (ethernet from raspberry pi). I ended up using TTN because it was easy and next to no modification of the example code from pycom was needed. I will let you know if I continue working on this
