Antra and Kayel:Can you tell me a little more about your topology? I am considering a Lora connection, not quite line of site, about 1.5 km with a gently rising and falling ridge in between.Thanks.
As soon as I started going down the other side of the ridge, NOTHING AT ALL. Maybe it's possible with special aerials or amplifiers, I don't know. I saw srnet's reply just before I posted, but posted anyway because you asked me a question.
Or maybe, at no extra cost at all, you just need to use the appropriate LoRa settings and get 10-16 times the range.
As far as possible, I used the power-on/reset values to keep it short and simple.
May not be a good idea in this case, the defaults may be illegal to use in your part of the world and\or could cause interference to essential services.
I read some of the legal guff and thought I was OK.
So what are these default settings that you were using ?
