NHS3100: NTAG® SmartSensor with Temperature Sensor and Digital IOs

NHS31XX evaluation kit: first steps

Dear customer,
Thank you for evaluating the NHS31XX chip.

Preparing the chip for demonstration purposes

1.1 Initial firmware

The firmware loaded in the chip is the One-time NFC program downloader. To demonstrate the Temperature Logger or Therapy Adherence use case, the corresponding firmware image needs to be downloaded in the FLASH memory of the NHS31xx chip.

Procedure

Programming takes three steps:

  1. Download and install the Android APP NHS31xx NFC Program Loader from the Google Play Store.
  2. Download the latest version of the firmware you're interested in - see UM11136.pdf
  3. Program the Demo PCB by holding it in the NFC field of your NFC-enabled Android Phone.

    Note: This can be carried out only once: when the new firmware is programmed, it is impossible to overwrite it wirelessly later. Changing firmware again is then only possible using a wired approach - see the next tab for instructions on how to do this.

Operation

The latest versions of different firmware demo applications are available as QR-codes in UM11136.pdf. After selecting a firmware image via the APP, tap the Demo PCB with your phone. Programming will start automatically. Keep the Demo PCB in a steady position beneath the NFC field of your phone until programming is complete.

Upon successful completion, the new firmware image will automatically start. The Demo PCB is now fully prepared, and you can use it for demonstration purposes immediately.

When programming fails - for example when the Demo PCB is removed from the NFC field - you can simply try again. Only once programming has completely finished, wireless downloading of other firmware is no longer possible.


Re-programming the chip

2.1 Changing firmware

The firmware residing the NHS31xx chip - whether it is the One-time NFC program downloader or one of the demo firmware images from the SDK or any other firmware image - can be replaced using a wired connection.

Procedure

This can be done in three steps:

  1. Download and install Flash Magic from flashmagictool.com
  2. Download the latest version of the firmware you're interested in - see UM11154.pdf
  3. Program the flash contents of the NHS31xx chip.

Operation

The latest versions of different firmware demo applications are available as direct download links in UM11154.pdf.

Download your firmware image of choice, and use Flash Magic to program the flash contents.

Upon successful completion, the new firmware image will automatically start. The Demo PCB is now fully prepared, and you can use it for demonstration purposes immediately.


Development using the Demo PCB

Prepare your workstation by downloading the latest SDK from the NHS3100 product page, and follow the steps outlined in docs/UM_NHS3100_GettingStarted.pdf.
