How to flash firmware on tracker tk103




Step 1: Download the device SDK for Python and extract the files




The first step is to download the device SDK for Python and extract the files to a directory on your computer. The device SDK is a software development kit that allows you to communicate with your device and upload firmware files. The device SDK for Python is compatible with Windows, Linux, and Mac OS systems.


You can download the device SDK for Python from this link. The link will take you to a page where you can find the latest version of the device SDK for Python and other related resources. The file name should be something like aws-iot-device-sdk-python-v2-x.x.x.zip (where x.x.x is the version number).


After downloading the file, you need to extract it using a tool like WinZip or 7-Zip. You should see a folder named aws-iot-device-sdk-python-v2-x.x.x (where x.x.x is the version number). Inside this folder, you should see two files: python_sdk.py and device_version.json. These are the files you will need for flashing firmware.


Step 2: Generate the device credentials using the python script




The next step is to generate the device credentials using the python script. The device credentials are a set of information that identify and authenticate your device with AWS IoT Core. AWS IoT Core is a cloud service that enables secure communication between devices and applications. The device credentials include:



  • Certificate: A digital document that contains information about your device's identity and public key.



  • Private key: A secret code that corresponds to your device's public key and allows it to sign messages.



  • Root CA certificate: A digital document that contains information about AWS IoT Core's identity and public key.



  • Endpoint address: A unique URL that identifies AWS IoT Core's server where your device connects.



You can generate these credentials using the python script python_sdk.py that you extracted in step 1. The python script is a wrapper script around the device_version.json file that contains information about your device's manufacturer (acmetracker) and model (tk103). The python script will use this information to create and register your device with AWS IoT Core and download the credentials files.


To run the python script, you need to open a command prompt (Windows) or terminal (Linux/Mac OS) window and navigate to the directory where you extracted the files in step 1. Then type:


python_sdk.py


The script will ask you for some inputs:



  • AWS access key ID: A unique identifier for your AWS account that allows you to access AWS services.



  • AWS secret access key: A secret code for your AWS account that allows you to access AWS services.



  • AWS region name: A geographical area where AWS services are located.




can verify that the firmware update was successful by checking the version number and the functionality of your tracker.


To check the version number of your tracker, follow these steps:



  • Open a command prompt (Windows) or terminal (Linux/Mac OS) window and navigate to the directory where you extracted the files in step 1.



  • Type the following command and press Enter:



python_sdk.py --get-version


The script will ask you for some inputs:



  • AWS access key ID: The same input that you entered in step 2.



  • AWS secret access key: The same input that you entered in step 2.



  • AWS region name: The same input that you entered in step 2.



  • Device ID: The same input that you entered in step 4.



The script will then connect to AWS IoT Core and send a command to your tracker to get its version number. You should see a message on the command prompt or terminal window that shows the version number of your tracker. The version number should match the one in the firmware file name that you uploaded in step 4.


To check the functionality of your tracker, follow these steps:



  • Disconnect your tracker from your computer and remove the USB cable.



  • Insert a SIM card with an active data plan into your tracker.



  • Turn on your tracker by pressing and holding the power button for a few seconds.



  • Wait for your tracker to register with the cellular network and get a GPS signal. You should see some LED indicators on your tracker that show its status.



  • Use your phone or app to send commands or queries to your tracker via SMS or GPRS. You should receive responses or alerts from your tracker as expected.



If you see any errors or issues with your tracker, you might need to troubleshoot them or contact your device manufacturer or provider for support.
