This question must have been asked 100’s of times already but I can’t really find it.
I have several devices that are fairly close to a gateway (same building) but I see that 60+% of the time their msgs are picked up by some remote gateway. The difference in RSSI and SNR is huge, -42 and 14 vs -136 and -11) and there doesn’t appear to be any correlation with the channels. As a result the ADR doesn’t really switch the device to a more optimal DR; wasting BW and power.
So I have two questions:
- Why doesn’t the local gateway pick up all the traffic?
- Would it make sense to ‘fix’ the devices to a DR1 or DR2? Although that would compromise the redundancy.
