The document outlines the firmware update procedure for SCUBAPRO ALADIN series dive computers, including the ALADIN SPORT/ONE/HOSE MATRIX, ALADIN A1, and ALADIN A2 models, using an Android mobile device. This guide ensures users can successfully update their dive computers to the latest firmware, enhancing functionality and maintaining optimal performance.
Function Description:
The primary function of this guide is to provide a step-by-step process for updating the firmware of SCUBAPRO ALADIN dive computers via an Android mobile device. Firmware updates are crucial for introducing new features, improving existing functionalities, correcting software bugs, and ensuring compatibility with the latest technological standards. By following this procedure, users can keep their dive computers up-to-date, thereby optimizing their diving experience with reliable and accurate data. The update process leverages Bluetooth communication between the dive computer and a mobile device running the LogTRAK application, streamlining what could otherwise be a complex technical task. This ensures that even users with limited technical expertise can perform the update successfully, maintaining the high performance and safety standards expected from SCUBAPRO equipment.
Usage Features:
The firmware update process incorporates several user-friendly features designed to make the experience as smooth as possible:
- Pre-update Checks: Before initiating the update, the guide emphasizes the importance of ensuring the dive computer has sufficient battery capacity (at least 5 segments). This critical step prevents interruptions during the update process due to power loss, which could potentially corrupt the device's firmware. If the battery capacity is too low, the update will not proceed, prompting the user to replace the battery first.
- Mobile Device Preparation: Users are instructed to switch off any battery and screen-saving modes on their mobile device. This prevents the device from entering a low-power state or suspending operations, which could interrupt the Bluetooth communication required for the update. Maintaining an active connection is vital for a successful firmware transfer.
- Bluetooth Activation: The guide clearly states the need to activate Bluetooth on both the dive computer and the mobile device. This establishes the wireless link necessary for data transfer between the two devices, a fundamental step for the LogTRAK application to recognize and communicate with the dive computer.
- LogTRAK Application Integration: The LogTRAK application serves as the central hub for managing the update. Users are guided to launch LogTRAK on their mobile device and establish a connection with their dive computer by pressing the "Connect" button. This application not only facilitates the firmware transfer but also provides notifications regarding available updates.
- Firmware Download and Selection: Upon connecting, LogTRAK will display an "Aladin Matrix info" notification, indicating that a new firmware version is available. Users are directed to click a download link to save the
.swu (software update) file to their mobile device's Downloads folder. Subsequently, they press the "FIRMWARE UPLOAD" button within LogTRAK and navigate to the Downloads folder to select the downloaded .swu file. This intuitive file selection process ensures the correct firmware is chosen for the update.
- Progress Monitoring: During the upload, the mobile device's display shows a progress bar, indicating the status of the software upload. This visual feedback keeps the user informed about the ongoing process, reducing uncertainty and allowing them to monitor the update's progression. The dive computer itself will also display "UP DA LE" (Update) during this phase, reinforcing that the update is in progress.
- Post-update Actions: After a successful software upload, the dive computer automatically begins reprogramming. Once the new software is programmed, the device performs internal checks and reboots. Specific instructions are provided for different ALADIN models on how to exit the update screen and return to the "Time and date" display, ensuring a smooth transition back to normal operation. For ALADIN MATRIX, a double press-and-hold of the right button is required, while for A1 and A2, a short press of the SEL/ESC button suffices.
Maintenance Features:
The document also includes a comprehensive troubleshooting section, which acts as a maintenance guide for common issues that may arise during or after the firmware update:
- Handling Failed Transfers: If the firmware transfer fails, the LogTRAK application will display a "Transfer failed" message with instructions. Users are advised to press "OK," re-connect to their ALADIN dive computer, tap "FIRMWARE UPLOAD," and re-select the
.swu file. This iterative approach helps resolve temporary communication glitches or incomplete transfers. The guide acknowledges that depending on the Android device's age and model, multiple retries might be necessary to achieve 100% upload progress.
- Bluetooth Reconnection Issues: If the dive computer does not re-connect after a failed transfer, users are instructed to exit and re-enter the Bluetooth menu on their mobile device. This action can refresh the Bluetooth connection and resolve minor pairing issues.
- Bluetooth Connection Problems After Firmware Update: A common issue after a firmware update is an invalid Bluetooth pairing, as some mobile devices may not update to the new communication parameters. The guide provides a detailed sequence to resolve this:
- Unpairing: Users must unpair their ALADIN dive computer from their Android's Bluetooth settings by pressing "Unpair." This clears the old, potentially incompatible pairing information.
- Bluetooth Reset: Switching Bluetooth OFF and ON again on the mobile device helps reset the Bluetooth module, preparing it for a fresh connection.
- Scanning and Re-pairing: Users are then guided to scan for available devices, select "Aladin" to start the pairing sequence, and enter a 6-digit PIN code when prompted. This re-establishes a secure and compatible Bluetooth connection.
- LogTRAK Re-entry: Finally, users are instructed to exit the Bluetooth menu on their ALADIN dive computer, re-activate Bluetooth Ready mode, launch LogTRAK, and connect to their ALADIN dive computer again. This ensures that LogTRAK recognizes the newly paired device and can resume normal operations, including future data synchronization and updates.
These maintenance features are crucial for ensuring the long-term usability and reliability of the ALADIN dive computers, empowering users to independently resolve common technical issues and keep their devices in optimal working condition.
