Hi Jason,
Thanks for the answer above. I’m trying to understand the implications of that answer.
According to LoRaWAN specification:
“The RX2 receive window uses a fixed frequency and data rate. The default parameters are 869.525 MHz / DR0 (SF12, 125 kHz).”
It sounds like Multitech is instead using SF9BW125 by default for the receive window by default? Or do downlink messages have a completely different set of configuration and constraints from uplink?
(Out of curiosity, is this controlled by the network server or the packet forwarder? )
I think the specific concern we’re trying to address is, if a remote device at long distance is only able to uplink at SF10, and SF9 is not enough to send the downlink to the remote, then
a) does that not mean the downlink will never reach a very distant device in this case?
b) if so, then how do we force the network server to use SF10BW125 for the this specific downlink (or if that granularity isn’t possible, downlinks for this remote device).
I’ve found precious little on any of the nuances of downlinks on LoRaWan (in general, or on the network server multitech uses) – do you have any links to documentation or similar that might help us find some of this?
Thank you so much for the help!
