Hi everyone,
I got a TTN gateway a couple of months ago, as well as two boards to evaluate the system and to play around with. Now I wanted to see what the maximum range is in my environment (urban) and so I set the node to OTAA and programmed it to send a message every couple of minutes. Everything works fine, but the device sticks to SF8 and looses connection once I’m a couple of hundred meters away.
Now here comes the questions: When I want to dynamically adjust the SF the device uses, is this something that my node has to handle or is this automatically negotiated with the gateway? And if I have to do it, how is it done in LMiC? I couldn’t find anything in their documentation (only in the ABP example from their repository where you could hard code the SF to be 12).
Thanks for any hints!
Marco
