Modified on Mon, 19 Oct at 10:06 AM

This article explains how to create a transmission log from an iMETOS 3.3 station and send it to METOS Support when requested. Providing a correct log helps our support team diagnose issues faster and reduce resolution time.


Important Notes Before You Start

Before generating and sending a transmission log, please ensure:

  • Your iMETOS 3.3 is running the latest firmware

  • The station battery is charged to approximately 6.5V

  • You follow all steps exactly as described

⚠️ Logs sent without the required settings may delay troubleshooting.


Prerequisites

Before you start, ensure you have:

  • A computer with PI Service Terminal installed

  • A mini USB cable that supports data transfer

  • Physical access to the iMETOS 3.3 station

  • A charged battery (~6.5V)

  • No jumper is required for this operation


Step 1. Install PI Service Terminal

  • Download the latest release of PI Service Terminal - LINK

  • Install the application - LINK 

  • Launch the application on your computer


Step 2. Connect the iMETOS 3.3 Station

  1. Plug in the USB cable

  2. Turn on the iMETOS 3.3

  3. In PI Service Terminal, make sure the following options are enabled:

    • ✅ Save to Log

    • ✅ Timestamp

⚠️ These options are essential for METOS Support team to analyze the log correctly.

  1. Click Connect


Step 3. Wait for the Connection to Complete

  • The connection process may take several minutes

  • During this time, the screen may display ### - this is normal, just wait

  • The process is complete when the yellow LED stops blinking

➡️ If nothing appears on the screen:

  1. Disconnect the battery and solar panel

  2. Wait 30 seconds

  3. Reconnect both

  4. Repeat the steps above


Step 4. Retrieving and Sending the Log

  • The log is automatically saved once Save to Log is enabled

  • The file location is shown in the status bar of PI Service Terminal

To send the log:

  • Open the folder shown in the status bar or

  • Click Send in PI Service Terminal

  • Fill in the required fields

  • Send the log via email


Understanding LED Behavior (Helpful for Troubleshooting)

  • Startup phase:

    • Yellow LED blinks with 0.5-second pauses

  • Transmission phase:

    • Yellow LED blinks with 1-second pauses

    • Number of blinks (1–4) may vary during transmission

⚠️ Startup time can be longer if the station memory is heavily loaded.


Common Issues & Solutions

Issue Battery Depleting

(Example: 6.7 V → ~6.2 V) or below minimum operating threshold ➡️ Battery Thresholds – LINK  


A depleted battery can occur for several reasons. The most frequent causes include:

  • Solar panel is shaded
  • Solar panel not detected
  • Oxidized or loose battery cables
  • Battery has reached the end of its lifespan
  • Network issues causing the station or modem to hang
  • Firmware bugs

Check the following

  • Ensure the solar panel is not shaded
  • Confirm the solar panel is plugged in correctly
  • Verify the solar panel cable/plug is not oxidized
  • Ensure the solar panel cable/plug is not loose
  • Ensure the device is running with the latest firmware release → Refer to: “4. Check the Firmware Version”

Suggested solutions (if voltage is below the recommended threshold)

  • Replace the battery or
  • Recharge the battery


Issue No COM Port Appears in PI Service Terminal

Check the following

  • Battery voltage:
    • ~6.5 V → METOS 5, µMETOS, iMETOS 3.3 / ECO D3
    • ~3.6 V → nMETOS, LoRAIN, LoRATH family
  • Battery cable is properly connected on both ends of the battery and the connector
  • USB cable supports data transfer (some USB cables are power‑only)

Suggested solutions (if the issue persists)

  • Try using another battery
  • Try using another USB cable
  • Go to PI Service Terminal → Settings → Reset all settings


Modem Not Responding

Responses Example:

  • LTE/NBIoT Module Rebooting (Hard Reset)... Failed or Baud Rate Not Found
  • Modem AT interface not responding... no echo

Check the following
