ANT Broadcast

This example requires the following SoftDevice: S212

Important: Before you run this example, make sure to program the SoftDevice.

The Broadcast example consists of basic example applications that can be used to test ANT connectivity between a master and a slave.

Transmitter

The transmitter application transmits a packet four times per second. Each transmission is indicated by BSP_INDICATE_SENT_OK.

Packet layout: {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, X}

The last byte of the packet (X) is incremented each time.

You can find the source code and the project file of the example in the following folder: <InstallFolder>\examples\ant\ant_broadcast\tx

Receiver

The receiver application receives a packet four times per second. Each successful transmission is indicated by BSP_INDICATE_RCV_OK.

You can find the source code and the project file of the example in the following folder: <InstallFolder>\examples\ant\ant_broadcast\rx

Channel configuration

This example uses the default channel configuration:

Parameter	Transmitter	Receiver
Channel type	Master (0x10)	Slave (0x00)
Network key	Public	Public
RF channel	66 (2466 MHz)	66 (2466 MHz)
Device number	0x02	0x00 (Wildcard)
Device type	0x02	0x00 (Wildcard)
Transmission type	0x01	0x00 (Wildcard)
Channel period	8192 (4 Hz)	8192 (4 Hz)

Testing

Note: You can use a custom channel or encryption when running any of the ANT examples. When adding a new channel or encryption, remember to update SoftDevice ANT event handler configuration.

You can test the Broadcast example in different ways:

• Testing the Broadcast Transmitter with the Broadcast Receiver
• Testing the Broadcast Transmitter using ANTware II
• Testing the Broadcast Receiver using ANTware II

Testing the Broadcast Transmitter with the Broadcast Receiver

1. Compile and program the Broadcast Transmitter. Observe that the transmitter board indicates BSP_INDICATE_SENT_OK (4 Hz).
2. Compile and program the Broadcast Receiver. Observe that the receiver board indicates BSP_INDICATE_RCV_OK (4 Hz).

Testing the Broadcast Transmitter using ANTware II

1. Compile and program the Broadcast Transmitter. Observe that the transmitter board indicates BSP_INDICATE_SENT_OK (4 Hz).
2. Run ANTware II. Select your ANT PC dongle (for example, ANTUSB-m) from the available devices. Configure the device channels by loading the device profile configuration from the following file: <InstallFolder>\examples\ant\ant_broadcast\tx\ant_broadcast_tx_test.xml. Alternatively, you can configure the device channels manually:
   1. Set the channel assignment to slave.
   2. Set the channel ID to "0, 0, 0".
3. Click the Auto-Open button. Observe that messages describing the received payload appear for each ANT message. These messages should look similar to the following fragment:
   

   Received BROADCAST_DATA_0x4E
     :: 4e, 00-00-00-00-00-00-00-00-01
   Received BROADCAST_DATA_0x4E
     :: 4e, 00-00-00-00-00-00-00-00-02
   Received BROADCAST_DATA_0x4E
     :: 4e, 00-00-00-00-00-00-00-00-03
   Received BROADCAST_DATA_0x4E
     :: 4e, 00-00-00-00-00-00-00-00-04
   Received BROADCAST_DATA_0x4E
     :: 4e, 00-00-00-00-00-00-00-00-05
   Received BROADCAST_DATA_0x4E
     :: 4e, 00-00-00-00-00-00-00-00-06
   

Testing the Broadcast Receiver using ANTware II

1. Compile and program the Broadcast Receiver. Observe that the receiver board indicates BSP_INDICATE_RCV_OK (4 Hz).
2. Run ANTware II. Select your ANT PC dongle (for example, ANTUSB-m) from the available devices. Configure the device channels by loading the device profile configuration from the following file: <InstallFolder>\examples\ant\ant_broadcast\rx\ant_broadcast_rx_test.xml. Alternatively, you can configure the device channels manually:
   1. Set the channel assignment to master.
   2. Set the channel ID to "2, 2, 1".
3. Click the Auto-Open button. Observe that the receiver board indicates BSP_INDICATE_RCV_OK (4 Hz).
