I have 19 Gateways in Merano.
5 Gateways on Mountain Roads Arrondissement the City on high Positions. 14 dow in the Cities on Light poles.
The problem is that sometimes Chirpstack choose for Join request Gateways with really low RSSI and SNR. How can i can avoid that Gateways on Not good positions are sending the join accept?

ChirpStack chooses the downlink gateway as follow:

Based on the gateways reporting the uplink, it will sort these gateways based on SNR, and in case the SNR is equal on RSSI.

It will then create a new list of gateways, of which the link-margin is above the configured treshold (default 10). If that list is not empty, it will select a random gateways out of this sub-set.

In case the sub-set is empty, it will select the top gateway from the sorted list.

Since the latest version, there is also the possibility to add a downlink priority to each gateway which could help you to de-prioritize or prioritize certain gateways.
