9 Roaming use cases

NORA-W36 supportes roaming, it is disabled by default and needs to be enabled before connecting Wi-Fi with AT+UWSROE=1

The most important setting are the following, see AT manual for more settings

With the default value roaming will start if RSSI goes to -70 or below, a background scan will start to find a better AP with the same SSID. It will perform a roaming if an Access Point with -70+10=-60dBm is found.

Is some situations you want to roam based on your current RSSI instead of a fixed value (default -60 dBm), then the Aggressive roaming should be used AT+UWSROS3=1 and also lower the limit for a better AP to like 3 dBm AT+UWSROS1=3. Then if the current RSSI is like -78dBm it will be like -78+3=-75dBm and change will happen if an AP with -75dBm or better is found a roaming will occur.
