Subject: travelmate: update 1.2.0
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2d25b194d2feeb4b5b9ed65e0098dae3b72d64ee;p=feed%2Fpackages.git

travelmate: update 1.2.0

* union 'automatic' and 'trigger' mode, now much more responsive
  if an uplink suddenly disappears
* tidy up (disable) travelmate related uplink connections
  if you disable the service
* change default config ('trm_automatic' removal)
* documentation update
* LuCI: remove needless 'automatic' and 'trigger' options
  plus small fixes

 ## FAQ
-**Q:** What's about 'trigger' and 'automatic' mode?  
-**A:** In "trigger" mode travelmate will be triggered solely by procd interface down events, whenever an uplink disappears travelmate tries n times (default 3) to find a new uplink or reconnect to the old one. The 'automatic' mode keeps travelmate in an active state and checks every n seconds the connection status / the uplink availability regardless of procd event trigger.  
-
 **Q:** What happen with misconfigured uplinks, e.g. due to outdated wlan passwords?  
-**A:** Travelmate tries n times (default 3) to connect, then the respective uplink SSID will be marked / renamed to '_SSID_\_err'. In this case use the builtin wireless station manager to update your wireless credentials.  
+**A:** Travelmate tries n times (default 3) to connect, then the respective uplink SSID will be marked / renamed to '_SSID_\_err' and travelmate no longer attends this uplink. In this case use the builtin wireless station manager to update your wireless credentials.  
+**Q:** How to connect to hidden uplinks?  
+**A:** See 'example\_hidden' STA configuration above, option 'SSID' and 'BSSID' must be specified for successful connections.
