UART

A UART interface is available on the AUG-SL01 smart lock running the factory firmware (788113bb). This interface provides useful debug output (no input). In particular this output provides excellent information about how the lock is interpreting commands it receives over BLE.

Example output

What you will need

• A soldering iron
• 30AWG wire
• Masking tape
• Marker
• 3.3v FTDI usb to serial adapter (a bus pirate can also be used)

Solder to Uart Pads

Solder wires the the pads labeled in the above picture. While the pads are very small the fact that they are through hole will greatly aid in soldering. Do yourself a favor and label every wire shortly after soldering it with masking tape and a marker. While you are at it, you might want to consider soldering wires onto the JTAG pads.
