Registering your u-blox AWS IoT ExpressLink SARA-R5 module with your AWS account involves a few key steps. Here's a detailed guide:
-
Module Setup:
- Insert the provided Thingstream SIM card into the u-blox SARA-R5 module board.
- Attach a cellular antenna to the LTE antenna connector on the board.
- Ensure you are within range of an LTE-M cellular network.
- Connect the board to your host computer using the USB-C connection.
- Open a serial terminal application on your computer and configure it with these settings: baud rate 115200, end of line: line feed, local echo: yes, and no flow control.
-
Performing a 'Dummy' CONNECT:
- Find your AWS account 'Endpoint' string in the AWS IoT Console.
- Power on the cellular module by pressing the 'SARA On' button on the carrier board.
- In the terminal application, type the command 'AT+CONF EndPoint=' followed by your endpoint string and press Enter. You should receive an OK response.
- Type the command 'AT+CONNECT' and press Enter. This might take some time and could initially fail.
-
Registering with Your AWS Account:
- Go to the AWS IoT Console and navigate to Manage > Things.
- Create a new Thing. You will need the ThingName and certificate from your module.
- In the terminal application, type 'AT+CONF? ThingName' and press Enter to get the ThingName.
- Then, type 'AT+CONF? Certificate' and press Enter to get the certificate.
- In your AWS account, create the Thing, upload the certificate you obtained, and create a policy.
- To connect to your AWS cloud account, type 'AT+CONNECT' in the terminal application and press Enter.
- To disconnect, type 'AT+DISCONNECT' and press Enter. These steps are designed to help you successfully register and begin using your u-blox AWS IoT ExpressLink SARA-R5 module for your IoT projects.
