1.1.3

On the Arduino side this is just a documentation update. The instructions have undergone some copyediting to make them clearer.

The Android app has been updated to version 1.5, which supports scrolling the terminal output and other cosmetic tweaks.

1.1.2

This update changes the way that 26- and 34-bit codes are displayed. They are now split so that the first 3-5 characters are the facility code (the top 8-16 bits) and the last 5 digits are the ID number (the bottom 16 bits).

Configuration options within the script have been expanded, so the timeout when entering a pin, lockout timer, lockout maximum time, and doorbell can all be disabled by setting the appropriate constant to "0".

The Android companion app has also been updated to a more recent API version, and will now automatically connect to the last used bluetooth address on startup.

1.1.0

This version fixes a security hole that could allow an attacker to view the codes as you enter them if you had a bluetooth or other wireless serial monitor attached to the Arduino. The new version, by default, hides codes in the serial output. This can be permanently disabled by setting the HIDE_CODES option at the top of the code to 0, or it can be temporarily disabled in use after entering the configuration code. When temporarily disabled, the reader will flash amber to warn that any codes entered may not be secure.
