Feature possible?: Wifi Roaming #453

Closed LichtiMC closed 2 years ago

LichtiMC commented 3 years ago

I wonder if it's technically possible to implement some sort of "manual wifi-roaming". For example, if the signal strength goes down below a specific value, a reconnect is being issued by valetudo.

I have 2 Accesspoints at home and unfortunately the signal gets lost if the vacuum robot drives away too far from AP1, even though it would have full strength wifi signal from AP2. (Of course SSID and keyphrase are the same on both APs)

iirc the wifi configuration of the base linux firmware of the robot (which is responsible for the wifi connection - not the valetudo gui) does not contain the roaming functionality like you're used to have on other devices like laptops or smartphones. The robot connects to one BSSID (exactly one AP) and keeps the connection as long as this BSSID is within reach. That's why the wifi roaming in spite of a second AP with the same SSID is not working. I might be wrong, but that's how I remember the situation.
