SF7 seems to be unreliable in EU1 TTN #43

Closed Quas7 closed 2 years ago

Quas7 commented 2 years ago

Hi, just wanted to share my experience with switching to the TTN v3 stack. It seems, that the standard frequency plan is SF9 for TTN. I tried for hours to get a reliable uplink and finally noticed the #define LORAWAN_SF DR_SF7 Changing to DR_SF9 improves reliability by 99% for me.

Maybe setting this to DR_SF9 by default could safe some users some trouble. Otherwise, just close this silently. :)

Edit: forgot to mention, that my gateway is 2m from my end devices - any data error rate is not killing SF7 vs SF9. ;)

was not an SF-issue but a frame counter problem. Issue solved via #44
