Automated Uploads with Transcend Wi-Fi SD Card

This is based on this article Transcend WIFI SD Hacks.

Files

SD only files

autorun.sh (sd root)
Sets-up our environment.
config.sh (.custom)
Configuration settings.

root-fs files

autoupload (.custom)
It is copied to /bin. This script automatically uploads pictures to the configured server. Runs once on start-up.
busybox-armv5l (.custom)
Copied to /sbin. Contains additional busybox functionality.

DHCP extensions

access.sh (.custom)
Starts background daemons if we are on trusted wireless nets. It is added to the /etc/dhcp.script.
ntpd.sh (.custom)

Host only files

inst
This is a script used to copy working files to the sdcard.

FTP Server

This script will automatically upload files to an FTP server. The server needs to be specially prepared. Specifically under the ftp_path directory you need to create sub-directories. The sub-directories need to be in the form:

xx.xx.xx.xx.xx.xx

Where this is the MAC address of the WIFI card, in hex with dot (.) separators and lowercase.

This directory has to be writeable to the FTP user. Also, in that directory, there should be two empty files:

.state.0
.state.1

These files should also be writeable to the FTP user.

Configuring the client

Configuring the client is through editing the file config.sh.

Basic Usage

Usage should be quite simple. Simply turn on the camera within the range of the trusted network. Thing should happen automatically.

Notes

Linux command to format SD card:

sudo mkdosfs -n C00LPIX -v /dev/sdb1

TODO

document stop/resume and how we handle ungraceful shutdown
include a status (uploading ... date ... etc)
or, send an e-mail (or other notification) when it starts and ends. Possible notification options:
- Telegram which has a CLI interface
- XMPP client and server
- IRC
