    N5 Starter Kit SDK Version 2.0 and a New ANT Debugging Tool

    A new version of the N5 Starter Kit SDK has been released and is available for download. This update contains new reference designs for the nRF51422 including:

    ANT Background Scanning Demo
    Shows how to setup and use background scanning.

    ANT Relay Demo
    Demonstrates how to relay a message across multiple nodes by daisy chaining several devices together.

    ANT Auto Shared Channel Demo
    Shows how a shared channel network can be implemented using a master device and multiple slaves. This demo implements a handshaking mechanism to demonstrate how slave devices may be added and removed dynamically to and from the network.

    ANT Bootloader/DFU Demo
    Demonstrates how Over-the-Air (OTA) Device Firmware Updates (DFU) can be performed to wirelessly update the application, bootloader or SoftDevice.

    ANT Debug Demo
    Shows a sample implementation of debug messages which may be used to transmit useful information for debugging an application over ANT. It transmits the value stored in the device’s GPIO register, the state of the buttons on device, and some information about the health of the ANT channel.

    Refer to the N5 Starter Kit SDK User’s Manual for more information.

     

    A new debugging tool, ObservANT, is also available for download.

    ObservANT is a PC application which facilitates the debugging of applications wirelessly over ANT.

    Often it is difficult to debug embedded applications in place. For example, it may be inconvenient or impossible to attach debug wires to devices housed in restrictive enclosures, devices which have no debug pins exposed, or devices which are mounted in an inconvenient location such as a bicycle wheel or running shoe. A solution to this problem is to open an ANT channel for debugging and transmit the relevant information wirelessly. By formatting the debug information into debug messages, as defined in the ObservANT User Guide, ObservANT can display and log the data in a convenient way.

    The information being transmitted is up to the user, but may include things like register values, counter variables, current state of a state machine, ANT channel reception statistics, etc. ObservANT many be configured to display data as hex values, unsigned numbers, signed numbers or enumerations to match the type of information being sent by the device. Furthermore, ObservANT may send messages back to the device to request specific debug information.

    For more information see the ObservANT User's Guide and the previously mentioned ANT Debug Demo, which provides a sample implementation of debug messaging for use with ObservANT.

    Demystifying ANT Topologies - 1

    Part I. Building Blocks

    The ANT protocol has been designed with flexibility in mind, supporting a variety of network topologies by offering several "building blocks" that can be mixed and matched as desired.

    The Nordic Tech Tour is Underway!

    European engineers and developers are increasing their ANT skillset this May. The Nordic Tech Tour is being supported by one of the senior engineers from the ANT Applications Team, Alejandra Cano Tinoco, as she and a team of Nordic FAE/R&D personnel present a series of live workshops in key cities across Europe. The tour is designed to showcase the capabilities of the N5 module and nRF51 SoC; and includes an in-depth discussion of the flexibility of ANT. A hands-on demonstration will show how to create extended topologies from individual ANT building blocks.

    John Leonard, from Nordic Semiconductor describes the value of the sessions:

    "This will be a genuine and unique opportunity for developers to meet some of the world's most experienced and knowledgeable ULP wireless specialists and kickstart their next ANT+ or Bluetooth Smart product development within a single day. The day’s event will include an application walkthrough showing how to bridge the flexibility and extensibility of ANT networks to Bluetooth Smart Ready mobile devices.”

    Need to talk to phones? Use ANT!

    As per the press releases from last week, ANT is now in Samsung phones, Sony phones, and MediaTek’s new combo connectivity chip. So what does this add up to for developers and how many phones can ANT/ANT+ apps now work with?

    Today, the answer is that around 60 million phones have native ANT support. For comparison, approx 1 billion smartphones shipped last year globally, of which approx 80% run Android. (See below for info on connecting to phones without native ANT support.)

    Why you need to know about ANT+ Device Profile development

    If you work with ANT+ products, then you work with ANT+ Device Profiles on some level. By definition, every ANT+ product implements at least one ANT+ Device Profile; making it interoperable with other ANT+ products that implement the same ANT+ Device Profile.

    Network Keys and the ANT+ Managed Network

    The network key is one of the channel configuration parameters that must be set correctly for devices to communicate. It is used to identify which network the device will operate on, and for ANT devices the radio will not hear transmissions occurring on other networks. The newest ANT devices can store up to 8 network keys at a time (older ANT devices can typically store up to 3) as network numbers 0 - 7 (or 0 - 2). Each ANT channel is then configured to use a specific network number.

    IMPORTANT! - Critical Update to ANT-FS Reference Design

    We have recently updated the ANT-FS Embedded Client Reference Design to address an incorrect definition for the default transmit power value. Previously this value was set to -20dBm even though the associated comment indicated that it was 0dBm. This could have resulted in poor RF performance and shorter than expected transmission distance between the ANT-FS Client and Host. The default transmit power has since been updated to 0dBm.

    If you have been using this reference design as a basis for an ANT-FS Client, please review the changes and verify that your application implements the proper behaviour.  For any questions or concerns regarding this issue please contact support@thisisant.com.

    Pairing: the fastest way to impress or distress your customers

    The ANT office is usually a peaceful place to the human ear, but there is no question that it is a busy wireless environment. So when we work with ANT+ devices, the pairing techniques employed by the product designers are either massively helpful - or drive us insane. Allow me to illustrate: imagine a bike computer has arrived to be certified, and our cert engineer needs to put it through a series of tests to check that it can receive and display the ANT+ data correctly.

    Pairing to Devices with Extended Device Numbers

    So you probably already know the basic concept of ANT connections: an ANT master transmits at regular intervals (e.g. 4Hz) and an ANT slave can then search for the master. Once the slave has found the master, it can switch it's radio on and off at the right times to be able to receive the master's transmissions. The slave can also send messages back to the master.

    New nRF51 and ANTUSB-m features

    The new nRF51422 SoC (System on a Chip)  and ANTUSB-m include several enhancements to the ANT protocol stack. These include:

    • Advanced Burst - maximum data throughput up to 60kpbs

    Advanced Burst is a method to allow transfers to have properties not supported by standard ANT messaging. These properties can include:

    • Burst packet sizes up to 24 bytes
    • Frequency Hopping per Transfer Pair

    Advanced Burst will not be enabled by default. Sub features (maximum packet size, frequency hopping, etc.) can be enabled/disabled separately.  Advanced Burst is intended to facilitate and improve the ability of devices to transfer information. ANT-FS use cases would be the primary concern, with an emphasis on longer file transfers. Advanced Burst will improve the efficiency of transferring a file over ANT-FS by increasing the transfer speed and providing FH to provide a greater immunity to RF interference. It will also make the transfer less susceptible to failure when faced with a slow throughput from the host.
