# travelmate, a connection manager for travel router
# travelmate, a wlan connection manager for travel router
## Description
If you’re planning an upcoming vacation or a business trip, taking your laptop, tablet or smartphone give you the ability to connect with friends or complete work on the go. But many hotels don’t have a secure wireless network setup or you’re limited on using a single device at once. Investing in a portable, mini travel router is a great way to connect all of your devices at once while having total control over your own personalized wireless network.

## OpenWrt / LEDE trunk Installation & Usage
* install 'travelmate' (_opkg install travelmate_)
* configure your network to support (multiple) wlan uplinks and set travelmate config options (details see below)
* set 'trm\_enabled' option in travelmate config to '1'
* travelmate starts automatically during boot, triggered by procd as soon as the wireless subsystem is up & running
## Chaos Calmer installation notes
* 'travelmate' is _not_ available as an ipk package in the Chaos Calmer download repository
* download the package from a development snapshot package directory:
* for 'travelmate' look [here](https://downloads.lede-project.org/snapshots/packages/x86_64/packages/)
* download the package from a development snapshot package directory, i.e. look [here](https://downloads.lede-project.org/snapshots/packages/x86_64/packages/)
* manually transfer the package to your routers temp directory (with tools like _sshfs_ or _winscp_)
* install the package as described above

* mandatory config options:
* trm\_enabled => main switch to enable/disable the travelmate service (default: '0', disabled)
* trm\_loop => loop timeout in seconds for wlan monitoring (default: '30')
* trm\_maxretry => how many times should travelmate try to connect to uplink xyz (default: '3')
* trm\_maxretry => how many times should travelmate try to connect to a certain uplink (default: '3')
* optional config options:
* trm\_debug => enable/disable debug logging (default: '0', disabled)
* trm\_device => limit travelmate to a dedicated radio, i.e 'radio0' (default: '', use all radios)
* trm\_iw => force travelmate to use iwinfo (even if iw is installed) set this option to 'none' (default: '', use iw if found)
