6 wireless technologies for wearables

Are you creating a wearable product, but not sure of what wireless technology to choose? The way modern APIs work, developers don’t necessarily need to know the technical details. But having a basic understanding of the underlying technology will help you make apps that are more efficient, more responsive and easier to use.

Which solution is best for your wearable product? This depends on your requirements for bandwidth, power considerations and range. Here’s a brief overview of the 6 most common wireless technologies to consider.

Advances in technology mean that smart clothes are moving away from the preserve of fitness fanatics and heading squarely into the mainstream. But what if our clothes could tell us not only how we’re doing but how they’re doing as well?

Outline

  • Errata affecting the current measurements
  • DCDC does not automatically switch off in System ON IDLE
  • NFCT can draw current when not enabled
  • Measurements
  • Results
  • Test setup: Power analyzer
  • Power Analyzer Measurements
  • Test setup: Oscilloscope and ampere-meter
  • Oscilloscope Measurements
Preparing the development kit The USB connector must not be used to power the board during measurements as it will give unreliable results due to added supply and measurement noise when the debugger chip USB port is active. The board should be powered from a coin cell battery, or using the External Supply pins P21 for current measurements.

Firmware updates for smart technologies

In the fast-moving world of the Internet of Things, it’s more important than ever to make sure you can keep your products up to date quickly, securely and easily. Updating firmware remotely brings benefits to both companies and consumers.

When designing your product, it’s crucial that you choose a memory technology that lets you update your firmware easily. Otherwise, you may have to scrap a lot of products if you find errors. If this happens after they've been shipped to end customers, the negative impacts will be severe.

Firmware is held in non-volatile memory such as ROM, EPROM or flash memory. Let’s take a closer look at one of them: flash memory, which enables device firmware updates (DFU) and the advantages that this gives.
