TP-Link WA850RE Signal Leds problem Fix (LEDE 17.01.2)

For Developers
1

Greetings i have noticed that the wa850re v1.2 leds don't work as intended when using WDS.

I have configured 2 networks: WDS Client (wlan0) and WDS AP (wlan0-1), but the signal leds don't light up,wireless keeps flashing.

Edit: i found out that the problem with signal leds it's missing package
Fix:
install rssileds

opkg install http://downloads.lede-project.org/releases/packages-17.01/mips_24kc/base/rssileds_0.2-1_mips_24kc.ipk

OR

  1. Download http://downloads.lede-project.org/releases/packages-17.01/mips_24kc/base/rssileds_0.2-1_mips_24kc.ipk

  2. Transfer package via scp

  3. opkg install rssileds_0.2-1_mips_24kc.ipk

Optional extra:

WARNING! using Luci to configure leds will erase the config of the signal leds, edit /etc/config/system manually.

To have activity indication on 'wireless' and 're' leds edit /etc/config/system and:

  1. Add

config led 'led_re'
option name 'RE'
option sysfs 'tp-link:blue:re'
option trigger netdev
option dev 'wlan0'
option mode 'rx tx link'

  1. find config led 'led_wlan' and change

option trigger 'netdev'
option dev 'wlan0-1'
option mode 'rx tx link'

I first did a workaround (before i found out that rssidleds was missing) by modifying a script, i'll leave it here just in case if someone wants to use it, transfer it via scp and call it from /etc/rc.local (in LUCI system>startup>local startup) and don't forget to set execution permissions (chmod +x).
