Hi, first topic/post but I’ve been enjoying the setup phase here in a very rural location with lots of inconvenient hills. I’ve got two gateway’s running 24/7, one at 217m most of the way up a hill and one down in a valley, so I’m looking to map out reception.
I’ve read the TTN Mapper FAQ and acknowledge the wisdom of worst case scenario use of SF7, but the reality is that stops reception dead in its tracks with the wide variety of solid stone buildings we have. Particularly if my device just has a small helical antenna. Or I drive around the back of a hill.
I can drive around slowly with something set to SF9 or 10 with a more representative stubby aerial or even an external magmount whip antenna or put what we would imagine to be a typical outdoor config for more remote parts (IP67 enclosure with stubby on the outside) on the top of the car.
I’m not looking to get some insanely accurate results, just enough so we can setup some devices without having to constantly return to change them - much as I love hill walking.
It did occur to me that I could code a device so that if I don’t get a ping on TTNMapper app that I can increase the SF at a location until I do.
As I’m doing this mapping exercise with a purpose, I’m only transmitting one byte to keep the tx time to a minimum.
Any pointers or experiences to make my war-drive as representative as possible would be much appreciated.
