The first steps where cool but not really DIY. So I bought a set of 2 RFM95W LoRA trancievers with HOPE_RF Carrier boards and Arduino shields from IdeeTron. Started to experiment with them and after a few evenings playing around with them, messages where exchanged over the air between the 2 boards.
Again cool, but no LoRA WAN.
The first true LoRa WAN experiance
The problem with LoRA WAN is that when you really want to play, you need to have a gateway. And those things do cost some Euro or what every currency you like. But I'm in the lucky situation that next to the office where I work there is a nice high-tech company called KITT Engineering which DO have a TheThingsNetwork gateway (which is basically LoRA WAN for the public).
So again after a few hour programming and playing with the Arduino's the first HelloWorld was send over TheThingsNetwork.
And confirmed by the API of TheThinksNetwork (https://thethingsnetwork.org/api/v0/nodes/)
So that was a good start.
But there is room for improvement.
Next step : learning, getting information and making contacts.
