Help! How do i get technical support?

Our tech support pages (located here) are the best place to start. If you can't find an answer for your question, we recommend submitting it through our inquiry form, located here.

Do you offer example schematics, layout library files, or bill-of-materials?

For reference designs (including schematics, layout tips, and bill-of-materials), see the Hardware Design Guidelines application note located in the "Documentation & Videos" tab of our product pages. Additional examples can be found in our Solutions section.

For layout library files, please see the "Dev Tools & Software" tab of our product pages.

Do you offer schematic and layout checking services?

Yes, please feel free to contact us here to request a design review. We realize RF design is difficult and we are happy to assist you with your design.

What type of enclosure do you recommend for our wireless product?

Please see our Hardware Design Guidelines application note (located in the "Documentation & Videos" tab of our product pages) for enclosure and antenna placement recommendations.

I would like to make a hardware modification to your module. Can you help me with this?

CEL doesn't warranty hardware that is modified by end customers.

What is a mesh network? What is a star network?

In a mesh network, wireless nodes are connected with redundant interconnections. This helps to improve the reliability of the network, because if one node fails there are still other paths to get a message through the network.

In a routing mesh network, devices called routers are used to relay messages using a path determined by a networking algorithm. In a flood mesh network, messages are broadcast out by every non-sleepy node that receives the message.

In a star network, all end nodes are connected to one common central node, so all network communications pass through the central node. This creates a potential point of failure if the central node fails.

What are some of the tradeoffs in choosing an interoperable vs. proprietary standard for my product?

There are several benefits of choosing an interoperable standard, even if your product is planned to be used in a closed system:

  • An interoperable standard prevents you from being locked into one vendor if issues should arise down the road.
  • A lot of work goes into developing an interoperable standard, and you will be able to take advantage of the technical expertise of the many players that worked to develop and test the standard, freeing your team to focus on product innovation.
  • Additionally, a standards-based wireless transceiver will be produced in higher volume, lowering your costs.

Zigbee, thread, wifi, and bluetooth all operate in the 2.4ghz band. Should i be concerned about interference affecting my product?

All standards that operate in the 2.4GHz band (including ZigBee, Thread, WiFi, Bluetooth, etc.) include interference mitigation techniques to ensure robust communications, even when several standards are operating in the same environment.
