This webinar is built entirely on your questions, so feel free to ask anything related to the Notecard, Notehub, power requirements, and more!
What Certifications are Required When Using the Notecard?
One of the first questions we received was about the certifications needed when integrating the Notecard into your product. Ethan, can you shed some light on this?
Absolutely! The Notecard is both PTCRB and FCC certified, which significantly reduces the certification process for you as the product creator. However, it’s crucial to meet the regulatory requirements for the regions where your device will be deployed. For specific assistance, reach out to sales@blues.com. Remember, certification varies widely depending on the device type, so it’s best to consult with us for tailored guidance.
The Future of Software-Defined Cellular IoT Platforms
Next up, Sean, what are your thoughts on the future of software-defined cellular IoT platforms?
There’s a lot of excitement around software-defined cellular technology. While we don’t currently have plans for OTA updates from 4G to 5G, carriers have committed to supporting LTE Cat 1 and Cat M for at least the next decade. We’re also exploring options to reduce the form factor and cost of the Notecard by integrating it into a cellular module or a system on a chip. Stay tuned!
From Proof of Concept to Production
A question that frequently arises is how long it typically takes to move from proof of concept (POC) to production with the Notecard. What can you tell us about that process?
Great question! It usually takes anywhere from 12 to 18 months to go from POC to mass production. However, we have seen teams deploy solutions in as little as six months, which is quite aggressive. The Notecard can cut down on development time significantly by providing a reliable connectivity solution that most other module manufacturers don’t offer.
Verizon SIM Support
We’ve had numerous inquiries about whether the Notecard supports Verizon SIMs. Scott, can you clarify this for us?
The Notecard is not certified for Verizon, but many users have successfully tested it with Verizon SIMs in the Notecarrier. Just keep in mind that you may need to go through Verizon’s end device certification if you plan to deploy over 20 devices.
Working Without Notehub
Another popular question is whether the Notecard can function without Notehub. Sean, what’s your take?
While the Notecard is designed to work seamlessly with Notehub, you can technically host your own lightweight Notehub server. However, this may require a significant amount of support, and we recommend using Notehub for its built-in event management and routing capabilities.
Real-Time Operating System (RTOS) Support
Does the Notecard have support for RTOS? Zach, care to answer?
The Notecard does not specifically have RTOS support, but it does have a generic API that allows you to communicate via JSON. This means you can easily integrate it with various systems, whether they’re running RTOS or not.
Location Acquisition Options Beyond GPS
What options do we have for location acquisition outside of GPS? Sean?
We offer cellular triangulation as a power-efficient alternative to GPS. Additionally, we have an experimental feature for Wi-Fi triangulation that allows you to gather location data based on nearby access points. Just keep in mind that this feature is still in its technical preview stage.
Measuring Power Usage Over Time
How can developers measure power usage over time with the Notecard? Ethan, any tips?
Using a tool like the Current Ranger can help you monitor the power consumption of the Notecard. It idles at just 8 microamps, which is extremely low. By measuring power during sync operations, you can estimate battery life based on your usage patterns.
Adding Sensors to Sparrow
For those interested in adding sensors to Sparrow, what’s the process? Zach?
It’s relatively straightforward to add sensors to Sparrow. The GPIOs are accessible, and if you’re familiar with STM32 programming, you shouldn’t face any major hurdles. If you want to extend the range of your sensors, you can also consider using external antennas.
Recommended PCB Design Providers
What are some recommended providers for PCB design and production? Ethan?
We’ve partnered with several reputable design firms. For U.S. fabrication, I recommend Summit Interconnect and Circuit Hub. For overseas fabrication, PCBWay and JLCPCB are great options. If you need help finding the right fit, reach out to us!
Pros and Cons of Notecarrier F vs Custom PCB
Can you summarize the pros and cons of using Notecarrier F versus a custom PCB? Zach?
The main advantage of using Notecarrier F is that you don’t need an EE on staff. However, if you need a tailored solution, a custom PCB can save costs in the long run. It’s wise to weigh the initial investment against the potential savings.
Improving Cellular Connectivity
What tips do you have for improving cellular connectivity in rural areas? Sean, Zach?
Start by testing which carriers work best in your area. Using higher gain antennas can also help, and consider using cellular repeaters to boost weak signals. It’s also worth experimenting with different Notecard variants that better suit your location.
Managing IoT Data at Scale
For those looking to manage IoT data at scale, what recommendations do you have? Scott?
When scaling, consider using NoSQL databases like MongoDB, which are designed to handle the JSON data from the Notecard. We recommend using hosted providers like AWS for their reliability and ease of management.
Gathering Consecutive GPS Readings
Any tips for improving the gathering of consecutive GPS readings? Sean?
To improve GPS reading frequency, consider using an external GPS module. This allows for concurrent cellular and GPS operations, significantly increasing your reading cadence.
Notecard Outboard Firmware Update Feature
What untested MCUs can use the Blues Notecard Outboard Firmware Update feature? Ethan?
Currently, we’re focusing on microcontrollers with permanently burned-in bootloaders, like the STM32 series and ESP32 series. If you have a specific chipset in mind, feel free to reach out for further clarification.
Software Control of Cell Transmit Power
Does the Notecard support software control of cell transmit power? Sean?
The Notecard does not allow for direct control of cell transmit power; this is managed by the modem based on signal strength. However, you can optimize power consumption by configuring how frequently the Notecard syncs.
Sync Time with the Notecard
How long does a sync take with the Notecard? Sean?
The sync process typically takes about 20 to 30 seconds, depending on the modem variant and the network conditions. This includes the time for powering up, registering, and syncing data.
Azure IoT Central Template for the Notecard
Does an Azure IoT Central template exist for the Notecard? Scott?
While we don't have a specific template, we do provide a routing tutorial for Azure IoT Central on our website. This can guide you through the steps necessary to integrate the Notecard with Azure services.
