How to upgrade your PRECISION power meters firmware

For iOS users

Step-by-step instructions for upgrading the PRECISION power meter's firmware on iOS devices.

For Android users

Step-by-step instructions for upgrading the PRECISION power meter's firmware on Android devices.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

This document outlines the process for upgrading the firmware of the 4iiii PRECISION power meter to version 0.2.0, providing detailed instructions for both iOS and Android users. The PRECISION power meter is a device designed to measure power output during cycling, and regular firmware updates ensure optimal performance, accuracy, and access to new features.

Function Description

The 4iiii PRECISION power meter is a sophisticated cycling accessory that integrates with your bicycle's crank to provide real-time power measurement. This data is crucial for cyclists looking to monitor and improve their training, track performance, and optimize their riding efficiency. The device communicates wirelessly with compatible smartphones (iOS and Android) via Bluetooth, allowing users to configure settings, view data, and perform firmware updates through dedicated mobile applications. The core function of the PRECISION is to accurately quantify the power a cyclist generates, which is then transmitted to a paired device for display and analysis. The firmware, the internal software that controls the device's operations, is periodically updated to enhance its capabilities, correct any identified issues, and introduce new functionalities, ensuring the power meter remains at the forefront of cycling technology.

Usage Features

The upgrade process itself highlights several key usage features of the PRECISION power meter and its accompanying mobile applications.

• Wireless Connectivity: The PRECISION power meter relies on Bluetooth for communication with your smartphone. This wireless connection is fundamental for all configuration, data viewing, and firmware update tasks. Users must ensure Bluetooth is enabled on their device to establish a connection.
• Mobile Application Control: Both iOS and Android users interact with the PRECISION through dedicated mobile applications: the "4iiii" app for iOS and the "4iiii Device Configuration" app for Android. These apps serve as the primary interface for managing the power meter, including pairing, checking device status, and initiating firmware updates.
• Automatic and Manual Device Discovery: When opening the app, if the PRECISION has been previously connected and set as the default device, the app will attempt to connect automatically. This streamlines the user experience for frequent users. For new connections or if automatic connection fails, the app provides a manual search function (represented by a magnifying glass icon) to scan for all Bluetooth-enabled devices in range, allowing users to select their specific PRECISION unit.
• Firmware Update Mechanism: The apps facilitate a straightforward firmware update process. Once connected, users are prompted to upgrade to the latest version. The app displays the progress of the upgrade, keeping the user informed. This feature is critical for maintaining the device's performance and accessing the newest enhancements.
• Error Handling and Reconnection: The instructions acknowledge potential issues during the upgrade, such as connection failures or interrupted updates. The apps are designed to guide users through re-connecting and re-attempting the upgrade if it fails, demonstrating a degree of robustness in the update process.
• Battery Management: The importance of a fresh CR2032 battery before initiating an upgrade is emphasized. This highlights that the device is battery-powered and that sufficient power is crucial for stable operation and successful firmware updates. Users are also advised to replace the battery if they encounter persistent connection issues, indicating that battery status can affect connectivity.
• Crank Rotation for Wake-up: To initiate connection and interaction with the app, users are instructed to "wake up" the PRECISION by turning the crank 1-2 times. This motion-activated wake-up feature conserves battery life when the device is not in use.
• Default Device Naming: The document mentions that the default device name is "Precision," but users have the option to change it. This indicates a level of customization available to users, allowing them to personalize their device identification within the app.
• Confirmation of Update Success: After a successful upgrade, the app provides a confirmation message, and users are instructed to verify the new firmware version displayed on the "PRECISION Paired" or "PRECISION Connected" screen. This ensures that users can confirm the update has been applied correctly.
• "Fast Data Transfer" Option (Android Specific): Android users are presented with a "Use fast data transfer" option during the upgrade. While this feature aims to reduce update time, the instructions provide a crucial warning about its compatibility, advising users to uncheck it unless certain of their phone's capabilities. This demonstrates an awareness of device fragmentation in the Android ecosystem and provides guidance to prevent update failures.

Maintenance Features

The primary maintenance feature described in this document is the firmware upgrade process itself.

• Firmware Updates for Performance and Features: Regular firmware updates are a crucial aspect of maintaining the PRECISION power meter. These updates are not just about fixing bugs but also about enhancing performance, improving accuracy, and introducing new features that extend the device's capabilities. By providing a clear, step-by-step guide, 4iiii ensures that users can easily keep their device up-to-date, maximizing its lifespan and utility.
• Battery Replacement: While not a direct firmware feature, the instruction to "Ensure that you put a new CR2032 battery in your PRECISION before attempting to upgrade the firmware" highlights battery replacement as a routine maintenance task essential for the device's proper functioning, especially during critical operations like firmware updates. The advice to replace the battery if connection issues persist further emphasizes its role in device reliability.
• Troubleshooting Guidance: The document includes troubleshooting tips within the upgrade instructions, such as rotating the crank to refresh the device list or contacting support for persistent issues. This proactive guidance helps users resolve common problems independently, contributing to easier device maintenance.
• Support Contact: For issues that cannot be resolved through the provided steps, users are directed to contact support@4iiii.com. This indicates a dedicated support channel for more complex maintenance or technical problems, ensuring users have access to expert assistance when needed.
• Preventive Measures During Upgrade: Instructions like "do not turn off Bluetooth on your iOS device or quit the application" during an upgrade are preventive maintenance measures. They aim to avoid corrupting the firmware or requiring a restart of the update process, thereby ensuring a smooth and successful update and preventing potential device issues.

In summary, the 4iiii PRECISION power meter is designed for cyclists who demand accurate power data. Its usage is facilitated by intuitive mobile applications that enable wireless connectivity, device configuration, and, crucially, straightforward firmware updates. Maintenance primarily revolves around keeping the firmware current and ensuring adequate battery power, supported by clear troubleshooting advice and access to customer support.
