Fix VoCore2 LuCI no WPA Issue

WPA

Everything works, just add two lines to file: /usr/lib/lua/luci/model/cbi/admin_network/wifi.lua

+encr:value("psk", translate("WPA PSK"), {mode="ap"}, {mode="sta"})
+encr:value("psk2", translate("WPA2 PSK"), {mode="ap"}, {mode="sta"})

 

Here is the patch:

I will add this patch to later firmware at Apr :)

PoE Version Ready

Finally find the problem, it is simple and stupid, I place¬†an electrolytic capacitor at wrong direction… :)

Continue do more test…Hopefully tomorrow I will get good result.

PS: we contacted the factory about the lite version, sadly, they find the sample is not work, reason is simple,  crystal and a capacitor are short circuit, have to delay two days.

VoCore2: Process..

Good news is VoCore2 Lite batch almost done :) The factory will start test them tomorrow,  and we can ship all of them in this month.

Bad news is I get a lot of trouble when develop the PoE version… The heat, the strong EMC all solved but still something wrong.. Just feel like back to the noob time. :'(

I know, you know, everybody knows, as a developer, ¬†we always have¬†couple of days every month¬†— everywhere is a dead end…

Hope this pass soooon…

This is also why I love this job.

can not¬†write anymore…work, work :)

VoCore2 Firmware: Compile from Source

How stupid I am… I could do this months ago. Just remove the folder named bin, staging_dir, build_dir, dl, then compress, the source code is small enough to download.

 

1. install Ubuntu 14.04 64bit Server to Virtual Machine.

2. in virtualbox, we will need install some packages to compile openwrt:

sudo apt-get install gcc g++ binutils patch bzip2 flex bison make autoconf gettext texinfo unzip sharutils subversion libncurses5-dev ncurses-term zlib1g-dev libssl-dev python

3. download openwrt at vonger.cn/misc/vocore2/openwrt.tar.bz2

4. call “tar -jxvf openwrt.tar.bz2” to uncompress the package.

5. call “make menuconfig” in the openwrt folder, configure openwrt in menu, choose MT7688/28/VoCore2 in menu.

6. call “make” in the openwrt folder, start the make process

 

PS: recently I have no word about¬†the lame post carrier…

VoCore2: EAGLE version PCB

Now, we convert the raw PCB file to EAGLE. I guess this should help a lot of people who are using EAGLE :)

Source could download here: http://vonger.cn/misc/vocore2/source.zip, in the zip file name is vocore-eagle.pcb.

VoCore2: Convert into NAS

It is very simple to make SD card or a hard disk into Network Attached Storage.

Here is mine: I use it as a tiny git server to storage code, save some money to rent the private cloud on github :)

1. insert your microsd card(or USB disk) to VoCore2

once you insert the card or disk, you will find it mounted in /mnt.

mmcblk0p2 is for the SD card, sda2 is for USB disk.

2. setup ap+sta: read this blog http://vonger.cn/?p=2691
Or read the tutorial on vocore.io/v2u.html(do not forget setup /etc/config/firewall).

3. enable samba on VoCore2(latest firmware already have samba, please download at http://vonger.cn/misc/vocore2/ultimate.20161114.bin

Fill the path and any name you want, enable guest will allow everybody in your network view the share folder, be careful.
Note: do not forget click “Save & Apply”.

4. Now you can find your NAS every where :)

note1: you might need to setup your VoCore2 local ip. mine is 192.168.1.113.
uci set samba.@samba[0].interface=’127.0.0.1/8 lo 192.168.1.113/24 br-lan’
uci commit samba
/etc/init.d/samba restart

note2: you might need to setup your VoCore2 firewall.

VoCore2: AP + STA

It is not same as VoCore v1.

 

Just run this script every time you start VoCore2, you will able to make it into AP + STA mode.

If you do not run this script, it will go to AP mode.


uci set wireless.sta.ssid=[HOME AP SSID]
uci set wireless.sta.key=[AP PASSWORD]
uci set wireless.sta.network=wwan
uci set wireless.sta.disabled=0
uci commit
/etc/init.d/network restart
sleep 10
uci set wireless.sta.disabled=1
uci commit

This is not the best solution.
So I just remember one day Vernon Van Steenkist send me one script for VoCore.


#!/bin/sh
#
# Fix loss of AP when STA (Client) mode fails by reverting to default
# AP only configuration. Default AP configuration is assumed to be in
# /etc/config/wireless.ap-only
#

TIMEOUT=30
SLEEP=3

sta_err=0

while [ $(iwinfo | grep -c "ESSID: unknown") -ge 1 ]; do
let sta_err=$sta_err+1
if [ $((sta_err * SLEEP)) -ge $TIMEOUT ]; then
cp /etc/config/wireless.ap-only /etc/config/wireless
wifi up
# uncomment the following lines to try AP+STA after reboot
# sleep 3
# cp /etc/config/wireless.ap+sta /etc/config/wireless
break
fi

sleep $SLEEP

done

This code is clever, using iwinfo to check if the STA is in normal state.
If after 30 seconds we still can not get into STA mode, we back to AP mode.
This works for VoCore.

For VoCore2, it is slightly different. If we failed to connect to STA, it will not block AP mode.

We can do this to setup your home AP one time:


uci set wireless.sta.ssid=[HOME AP SSID]
uci set wireless.sta.key=[AP PASSWORD]
uci set wireless.sta.network=wwan
uci set wireless.sta.disabled=1
uci commit

then put the following code into rc.local(run at every startup)


uci set wireless.sta.disabled=0
uci commit
/etc/init.d/network restart
sleep 10
uci set wireless.sta.disabled=1
uci commit

After this, your VoCore2 is able to connect/disconnect STA automatically. Even carry VoCore2 to another position without your home ap, it will still working.

VoCore2: Video Tutorial Plan

1. Control LED
Control the on board purple LED, light/dark.
2. Light Sensor & Temperature Sensor
Read from a light sensor and temperature sensor, get environment parameters from sensor.
3. VPN Router(OpenVPN/Tor)
Create a VPN based on OpenVPN/Tor, secure your network.
4. File Share Server
Create your home file share server.
5. Wireless Camera
Control and monitor thought a camera.
6. Remote Digit Camera Control
Remote control a digit camera, you can capture photo remote.
7. Wireless Printer
Remote control a printer, no more USB wire or ethernet wire.

We already have two video¬†tutorials on youtube(search the magic word “VoCore2”):

1. Setup PPPoE, use VoCore2 as a normal router.
2. Use VoCore2 as an Airplay device to play music.

You will know how powerful VoCore2 is and what a real technical team can do!

Please continue help us share to makers/social media/press, if our indiegogo project could reach 100K USD everybody will get a secret gift. :)

PS: really busy recently :”)
