HooToo TripMate Nano (HT-TM02)

  • Device page
  • 360 MHz CPU, 8 MiB flash, 32 MiB RAM
  • Currently Installed: 19.07.10
  • Initial installation here
  • Can remove kernel PPP packages

Mode on Startup

Read status of buttons: 

root@wifi-ht:~# cat /sys/kernel/debug/gpio
 gpiochip0: GPIOs 0-21, parent: platform/10000600.gpio, 10000600.gpio:
 gpio-7   (                    |ht-tm02:blue:wlan   ) out lo    
 gpio-10  (                    |reset               ) in  hi    
 gpio-12  (                    |ht-tm02:green:lan   ) out lo    
 gpio-14  (                    |modeswitch          ) in  lo    
root@wifi-ht:~#

For modeswitch, "lo" is Wired, "hi" is WiFi position.

Could also use slide-switch package. Biggest advantage of this is that it triggers at boot time, not just a switch change. 

opkg install slide-switch

On startup On mode (button) change, copy files from /etc/config/config-wired or config-wireless to /etc/config with:

  • etc/rc.d/S15config-mode -> /etc/config/config-mode
#!/bin/sh
#
# Set mode according to slide switch
#

CONFIG=/etc/config

state=$(grep modeswitch /sys/kernel/debug/gpio | sed 's/.*\(lo\|hi\).*/\1/')
case "$state" in
        lo)
                mode="wired"
                ;;
        hi)
                mode="wireless"
                ;;
        *)
                echo "unknown"
                return 1
                ;;
esac

message="Using config mode: $mode"
echo $message
logger $message

config="$CONFIG/config-$mode"
for file in $(ls $config)
do
        echo $file
        cp "$config/$file" $CONFIG
done

Package Management

opkg update
opkg list
opkg list-installed
opkg install blah
opkg remove blah

Useful Additional Packages

  • ?

Reset

  • Controlled by /etc/rc.button/reset
  • Quick press of reset button reboots
  • Failsafe (long press) forces network to:
    • 192.168.1.1 / 255.255.255.0
    • SSH open with root / no password
    • "firstboot" command to revert to factory defaults
    • Hard factory reset (to 192.168.1.1.): umount /overlay && jffs2reset && reboot now
    • "mount_root" to mount root partition

Configuration and Commands

Misc

In /etc/config:

  • wireless
  • dhcp
  • system
  • network
  • firewall

Custom startup scripts:

  • /etc/rc.local

In /etc:

  • sysupgrade.conf

DHCP

Custom options may be given per network, eg: for NTP:

  • 42, 192.168.1.1

DNS

  • resolv.conf symlinked to /tmp/resolv.conf which points to local dnsmasq service which delivers from its cache or via DNS servers pointed to by proxies resolv.conf.auto (DHCP client updated)

Wifi commands

iw phy0 info
iw reg get
iw reg set GB

See other iw commands and Reg Database.

USB and File sharing

Add packages: 

opkg install kmod-usb-core kmod-usb-storage usbutils block-mount luci-app-minidlna

Show device: 

ls /dev/sd*
lsusb -t

Driver USB 1, 2, 3: uhci/ohci, ehci, xhci

Show device: 

# block info /dev/sda1
/dev/sda1: UUID="9814-E49A" LABEL="2" VERSION="FAT16" TYPE="vfat"

Mount FAT32 USB stick: 

/sbin/block mount
cd /mnt/sda1

LEDs

Buttons

procd interface: 

root@hootoo:/etc/rc.button# ls
BTN_0     failsafe  power     reset     rfkill
root@hootoo:/etc/rc.button#

scripts need to be named according to the button name, like "BTN_0" or "wps" (see here). They receive values:

  • $BUTTON: Name of button
  • $ACTION: "pressed", "timeout" or "released". For released, script returns timeout seconds (for hold down).
  • $SEEN: number of seconds
root@wifi-ht:/etc/rc.button# cat BTN_0 
#!/bin/sh

logger "Button $BUTTON: $ACTION (Seen $SEEN)"

return 0
root@wifi-ht:/etc/rc.button#

C2600

Has an additional "lights_toggle": 

[ "${ACTION}" = "released" ] || exit 0

led="c2600:white:general"
device="wifinet3"

logger "Button $ACTION, will toggle Guest Wifi"
echo 1 > /sys/class/leds/$led/brightness
case $(uci get wireless.$device.disabled) in
    0)
        uci set wireless.$device.disabled=1
        logger "Wifi disabled"
    ;;
    1)
        uci set wireless.$device.disabled=0
        logger "Wifi enabled"
    ;;
esac

wifi reload
service network reload
sleep 1
echo 0 > /sys/class/leds/$led/brightness

return 0

6in4

Requires packages: 6in4 luci-proto-ipv6 and used tunnel from Hurricane Electric.

  • Restart network
  • In LUCI, edit wan6 and change protocol from DHCPv6 to RFC4213
  • Set Remote IPv4 address (eg 74.82.46.6)
  • Set Local IPv6 address
  • Set IPv6 routed prefix (Routed /48)
  • Dynamic tunnel
    • Tunnel ID
    • HE username/password
ping ipv6.google.com

Manual Config: 

opkg install 6in4

uci set network.henet=interface
uci set network.henet.proto=6in4
uci set network.henet.peeraddr=[get IPv4 of HE gateway] 
uci set network.henet.ip6addr='[IPv6 from HE]'
uci set network.henet.tunnelid=[HE tunnel ID]
uci set network.henet.username=[HE username]
uci set network.henet.password='[HE password]'
uci commit network

uci set firewall.@zone[1].network='wan henet'
uci commit firewall

ifup henet
/etc/init.d/firewall restart
