How to Maintain Your Vehicle's Wi-Fi Connection
The following troubleshooting guide provides you tips for maintaining your vehicle's connection.
How to Troubleshoot Wi-Fi Connection If Your Vehicle's Wi-Fi LED Indicator Flashes Blue, Then Turns Red for Two Seconds, and Finally Off
Check the following to verify you have the valid Wi-Fi connection settings.
-
Verify that the USB drive has only one disk partition with only one wifi-creds.txt file on it. If multiple wifi-creds.txt files are found, all of them will be processed in the order they were found, which may lead to unpredictable behavior.
-
Verify the Wi-Fi network's SSID and password are correctly specified in wifi-creds.txt file. An example of this file is shown as follows:
################################################################################### # AWS DeepRacer # # File name: wifi-creds.txt # # # # ... # ################################################################################### # Provide your SSID and password below ssid: ' MyHomeWi-Fi' password: myWiFiPassword
-
Verify both the field names of
ssid
andpassword
in the wifi-creds.txt file are in lower case. -
Verify that each of the field name and value is separated by one colon (:). For example.
ssid : ' MyHomeWi-Fi'
-
Verify that the field value containing a space is enclosed by a pair of single quotes. On Mac, TextEdit or some other text editor shows single quotes as of the '...' form, but not of ‘...’. If the field value does not contain spaces, the value can be without single quotes.
What Does It Mean When the Vehicle's Wi-Fi or Power LED Indicator Flashes Blue?
If the USB drive contains wifi-creds.txt file, the Wi-Fi LED indicator flashes blue while the vehicle is attempting to connect to the Wi-Fi network specified in the file.
If the USB drive has the models
directory, the Power LED flashes blue while the vehicle is
attempting to load the model files inside the directory.
If the USB drive has both the wifi-creds.txt file and the models
directory, the vehicle will process the two sequentially, starting with an attempt to connect to Wi-Fi and then
loading models.
The Wi-Fi LED might also turn red for two seconds if the Wi-Fi connection attempt fails.
