Getting Logs from the Moped IoT

This guide explains how to access the IoT module in a Segway moped and extract diagnostic logs using a USB to TTL cable and the desktop diagnostic application.

Tools Required

• USB to TTL converter cable (see USB to TTL Cable guide)
• 3.95mm pentagonal bit (P bit)
• PH2 Phillips bit
• Desktop diagnostic program (contact Segway to obtain)
• Windows laptop

Steps

Step 1 - Disassemble the front panel:

Power off the moped. Remove 2 rubber stoppers. Remove 2 screws ST4.2×12 using the 3.95mm pentagonal bit (P1). Separate the front panel from the windshield (P2) and remove the panel (P3).

Step 2 - Remove inner protect plate and access IoT:

Remove 4 screws ST4.2×12 using a PH2 Phillips bit. Remove the front inner protect plate. Locate the IoT module and connect the USB to TTL cable to its diagnostic port.

If you need a USB to TTL converter cable, see the USB to TTL Cable guide.

Step 3 - Connect to laptop:

Connect the USB end of the cable to your Windows laptop. Open the desktop diagnostic program (download from Segway if needed).

Step 4 - Establish connection:

Select the correct COM port in the software and click Try to Connect. When connected, you will see device information. Click OK to proceed.

Step 5 - Capture logs:

In the main window, press Ctrl + L on your keyboard. A command window will appear. Enter the following commands in sequence:

1. Type log -na all and click Send
2. Type at+qfct=0803 and click Send
3. Type log -na all again and click Send

Step 6 - Save logs:

Wait approximately 10 minutes for log data to accumulate. Then click Save to download the log file to your PC.

To stop log printing at any time, type log -f all and click Send.

Sending Logs to Segway Support

After saving the log file, send it to Segway support along with:

• Moped serial number
• Description of the issue you are investigating
• When the issue started
