This allows bgscan modules to use more information to decide on when to perform background scans. bgscan_simple can now change between short and long background scan intervals based on signal strength and in addition, it can trigger immediate scans when the signal strength is detected to be dropping. bgscan_simple takes following parameters now: short interval:signal strength threshold:long interval For example: bgscan="simple:30:-45:300"
