IoT Kit Software
The NXP FRDM-K64F SBC
uses the ARM mBed operating software and associated
development tools. This allows all development to take place in a Web browser (e.g., Firefox,
Chrome, or Explorer) and removes the need to install tools on your PC. Once installed on the
Freedom board, the software uses various interfaces such as I2C, GPIOs, and UARTS.
At power up, the software configures the hardware and initializes the WNC-Shield card which
can take up to 60 seconds to complete.
Cellular Shield WNC 14A2A Firmware
Before assembling the kit or proceeding to the next steps, please ensure you are using the
latest WNC 14A2A firmware. Instructions for how to upgrade the firmware can be found on the
AT&T website:
https://starterkit.att.com/tutorials/cellular-shield-firmware-upgrade
Note: Please carefully read all of the instructions before performing the firmware upgrade, there
are several steps that are not intuitive.
Creating Online Accounts
There are five accounts required to use the IoT Kit:
1. Cloudconnectkits.org account for kit registration
2. Jasper account for SIM card registration
3. ARM Mbed.org account for compiling and modifying the SBC/WNC-Shield software
4. AT&T Flow account for implementing the sensor data
5. AT&T M2X account for an end-point device used by Flow. Essentially, this is the location where
sensor data is stored to and read from.
Cloudconnectkits.org Account
After obtaining the IoT Kit, it is best to register at
firmware/software updates as well as other information.
1. Navigate to www.
2. Press the
