What Bluetooth® technology does the Intel Curie module include?

The Intel Curie module includes an nRF51822-CEAAE0* Bluetooth® low energy device from Nordic Semiconductor. It is connected through I2C driver running a SoftDevice S130 stack or custom stack. The Nordic API can extend functionality for power management and over-the-air updates.

Nordic Semiconductor Product Information

What is the Bluetooth low energy interface and clock?

The nRF51822-CEAAE0 Bluetooth® low energy unit is interfaced to the Intel® Quark™ processor via a UART interface. The Nordic Semiconductor chip uses an ARM Cortex*-M0 processor running at 16 MHz. It also uses the 32 kHz, accurate real-time, crystal oscillator clock in the Intel Curie module during sleep.

Are Bluetooth low-energy GAP roles supported?

Yes, the unit can support GAP roles, depending on the software being used.

Are both Bluetooth low energy and Bluetooth classic technology supported?

The Nordic Semiconductor device only supports Bluetooth low energy technology. It does not support Bluetooth classic technology.

Can I upgrade my Bluetooth low energy firmware with updates from Nordic Semiconductor?

No, the image file has special application firmware that is part of image.bin. It needs to match the Nordic Semiconductor stack used in that image. This may change in future.

How much memory and storage does the Intel Curie module have?

The Intel® Curie™ module has:

  • 80 KB SRAM
  • 384 KB flash memory
What is the physical size and weight of the Intel Curie module?

Typical dimensions are 11 mm x 8.05 mm x 1.95 mm (±0.09 mm), and the module weighs about 25.5 grams.

What is the power input to the Intel Curie module?

The Intel Curie module is designed to operate on battery power, from a minimum of 1.9 V to a maximum of 4.4 V. The Intel Curie module may optionally be powered from a 1.8 V or 3.3 V regulator.

What are the power outputs from the Intel Curie module?

The Intel Curie module provides 1.8 V (100 mA) and 3.3 V (150 mA) output from an internal TI TPS62743 buck regulator (with an external inductor required).

What interfaces does the Intel Curie module support?

Interfaces on the Intel Curie module include:

  • Universal Serial Bus, version 1.1 (USB 1.1)
  • Universal asynchronous receive and transmit (UART)
  • Serial Peripheral Interface (SPI)
  • Inter-Integrated Circuit (I2C)
  • Pulse width modulation (PWM) output

Where can I find software support for the Intel Curie module?

Visit the Intel Curie module community forum or see the Intel® Curie™ Open Developer Kit (ODK)

 

Platform

 

Where can I have my own reference board built?

A local contract manufacturer or international service can build your reference and accessory boards. Some of them offer help with custom layouts to fit your exact needs. Premier Farnell has been enabled by Intel to provide support, and other partners are in the process.

Can I purchase an assembled and tested reference board?

Intel is working with Arduino* on the Arduino 101 board and Premier Farnell on the tinyTILE board to make such boards available.

What is the difference between Arduino 101 and Genuino 101*?

Genuino 101 is the brand name in some countries for the Arduino 101 board. There is no technical difference.

What is the physical size of the Arduino 101?

The Arduino 101 board measures 68.6 mm x 53.4 mm.

What is the physical size of the tinyTILE?

The tinyTILE board measures 36 mm x 26 mm x 5 mm, rounded up.

What if I have questions about my reference board?

Contact your reference board vendor for support.

How do I download my software to the Intel Curie module?

USB Device Firmware Upgrade (DFU) is the most common interface used to send commands and programs to the Intel Curie module. Other communication methods are also supported to a varying extent. For example, you can flash your code via JTAG, using Flyswatter2 or J-Link.

To download the Bluetooth block, refer to the Nordic Semiconductor website.

How can I program the Intel Curie module if I don't have a USB in my design?

A JLINK EDU or Flyswatter2 JTAG programmer can be used to program software for the Intel® Quark™ SE C1000 microcontroller, including Bluetooth® low energy firmware.

How can I meet input voltage requirements when using a battery source?

Please refer to the Intel Curie Module Design Guide for information on this topic.

Do I get lower power consumption using 1.8 V or 3.3 V supply (both are valid options)?

In general:

  • The lower-voltage design choice will have lower power consumption and will generate lower signal noise.
  • Depending on your selection, make sure the hardware design should follows datasheet and reference design guide recommendations. This ensures the design meets all interface signal-level requirements between the functional blocks.

For example, if you use a 1.8 V I/O voltage for the Intel Quark SE processor, be sure the Bluetooth low energy sub-system is also running at 1.8 V I/O voltage.

 

Software

 

Is power management supported on the Intel Curie module?

Yes, the Intel Curie has advanced power management functionality. The extent of support depends on the software being used.

Can I use an integrated development environment (IDE)?

Yes. The Arduino IDE is available for boards that are compatible with the Intel Curie module. This includes Arduino 101/Genuino 101 and tinyTILE boards. The Intel® Curie™ Open Developer Kit (ODK) is a command-line environment. You can configure your own tools to work with it.

How much memory and storage is available for an Arduino sketch?

24 KB of SRAM and 196 KB of flash memory is available for an Arduino sketch.

What software do the Arduino 101 and tinyTILE platforms support?
