Frequently Asked Questions

    Which microcontrollers does the Blues Wireless Notecard support?

    The Notecard is compatible with any microcontroller (MCU) from an 8-bit Arduino to 32-bit ESP32 or STM32 and every major Single Board Computer (SBC) platform. Some popular examples include the Adafruit Huzzah32, STM32 Nucleo, Arduino Nano, ESP32-WROOM, among many others. The Notecard communicates over either I2C or UART, so it acts as a peripheral that you can connect to a product’s existing I2C bus or UART connection.

    It’s also possible to communicate with the Notecard from any embedded language, including compiled languages like C and C++, to interpreted languages like Python and JavaScript.

    Which cellular networks does the Blues Wireless Notecard utilize?

    Different models of the Blues Wireless Notecard are available that connect to LTE-M, NB-IoT, and Cat-1 networks globally. When LTE-M, NB-IoT, or Cat-1 aren’t available, the Notecard is also supported by UMTS/HSPA+ and GSM/GPRS/EDGE wireless standards.

    Which countries does the Blues Wireless Notecard support?

    Global coverage is available in 135 countries, with direct support provided by leading providers and carriers. For a full list, please see our documentation article on Notecard’s supported countries.

    What is a cellular system-on-module (SoM)?

    A system on module (SoM) is a circuit board that integrates a system function on a single module/device. Unlike a single board computer like the Raspberry Pi or a microcontroller, a SoM generally serves a single special function.

    The Blues Wireless Notecard is a cellular SoM. The Notecard is a secure device-to-cloud data-pump that comes with 500MB of data and 5,000 monthly consumption credits. The Notecard itself is a tiny 30mm x 35mm SoM and ships ready to embed in a project via its m.2 connector. To make prototyping IoT solutions even easier, Blues Wireless also provides a series of expansion boards to host the Notecard called Notecarriers.

    What is the easiest cellular IoT board to start a project with? How do you add cellular to an IoT project

    The Blues Wireless Notecard, combined with the Notecarrier-AF, is the easiest way to add cellular connectivity to your MCU-based IoT project. Blues Wireless provides a Feather Starter Kit that includes a Adafruit ESP32 HUZZAH to get you started as quickly as possible. Alternatively, if you are invested in the Raspberry Pi platform, you can get started with the Raspberry Pi Starter Kit.

    What is a cellular IoT module?

    A cellular IoT module is a system on module (SoM) that integrates a system function (e.g. cellular) on a single module or device. Unlike a single board computer or a microcontroller, a SoM generally serves a single unique function.

    The Blues Wireless Notecard is a cellular IoT module. The Notecard is a secure device-to-cloud data-pump that comes with 500MB of data and 5,000 monthly consumption credits. The Notecard itself is a tiny 30mm x 35mm SoM and ships ready to embed in a project via its m.2 connector. To make things even easier, Blues Wireless also provides a series of expansion boards to host the Notecard called Notecarriers.

    Does the Blues Wireless Notecard require a Notecarrier to function?

    No! The Blues Wireless Notecard is a small 30mm x 35mm system on module (SoM) that is able to be embedded in any IoT project on its own via its M.2 edge connector.

    However, Blues Wireless provides a variety of Notecarrier host boards for easily adding cellular connectivity to a new or existing IoT solution for prototyping purposes. The Notecarrier also provides antennae for both the GPS and cellular capabilities of the Cellular Notecard (and the cellular antenna is also compatible with the Wi-Fi Notecard).

    Why can't I connect to my Notecard via USB?

    There’s two main reasons the Notecard may be having issues connecting to a computer via USB.

    1. The USB cable doesn’t support data (or it’s a faulty cable) - this happens more often than you might think.
    2. On Windows 7, a user needs to install a driver to support USB communication with the Notecard. See our forum article for more details on communicating with a Notecard on Windows 7.
    What do the Notecard LED blink patterns mean?

    For more information on Notecard LED blink patterns, see our forum article to decode what your Notecard’s LEDs mean.

    What can I do if a Notecard isn't connecting to the network?

    If the Notecard’s having trouble establishing a connection, please see our forum’s troubleshooting article on connecting to a cellular network.

    How do I gather a trace log from a Notecard?

    Trace information is a stream of messages that can be useful when looking to understand Notecard behavior, for instructions read our forum’s article on how to capture trace logs from a Notecard.
