For instance, many wireless repeaters and range extenders have a signal strength meter on them for the received signal. Step 1: installing rssileds opkg update opkg install rssileds Step 2: configuring the system The rssileds configuration is stored in the “system” UCI section. At least two sections are needed. rssileds configuration Name Type Required Default Description refresh integer yes (none) Refresh rate in microseconds threshold integer yes (none) The minimun required change in the quality to trigger a LED refresh action dev string yes (none) Specifies the used wireless adapter, must refer to one of the defined wifi-device sections The node name is used to link each LED rule to the rssi block configuration LED definitions Options available for the “rssi trigger”, for more details on other parameters refer to LED section in System configuration. Name Type Required Default Description iface string yes (none) Specifies the rssi block, must refer to the name defined in the “rssid” block sections minq integer yes (none) The minimum quality percentage for the LED to turn on maxq integer yes (none) The maximum quality percentage for the LED to turn on offset integer no 0 Used for PWM LED, the led brightness is equal to the quality with the specified offset factor integer no 1 Used for PWM LED, after the offset is applied, the brightness is scaled by the specified factor With PWM capable LEDs the brightness is calculated as: brightness = ( quality + offset ) * factor Any quality values outside the specified range will mean the LED is off Example config rssid 'wlan0' option refresh 40000 option threshold 1 option dev 'wlan0' config led 'rssilow' option trigger 'rssi' option name 'RSSILOW' option iface 'wlan0' option sysfs 'mt2681:green:rssilow' option minq '1' option maxq '100' option offset '0' option factor '6' config led 'rssimedium' option trigger 'rssi' option name 'RSSIMEDIUM' option iface 'wlan0' option sysfs 'mt2681:green:rssimed' option minq '30' option maxq '100' option offset '-29' option factor '5' config led 'rssihigh' option trigger 'rssi' option name 'RSSIHIGH' option iface 'wlan0' option sysfs 'mt2681:green:rssihigh' option minq '70' option maxq '100' option offset '-69' option factor '8' This website uses cookies.
