Detailed Description

When the application is booting, LED0 and LED1 are turned on. Once the SoftDevice is enabled, all LEDs are turned off to indicate the system is ready.

The device is set up to use Device Type: 2, Device Number: 2, Transmition Type: 1. The channel period is set to 4 Hz (8192). When a successful broadcast has occured it will turn on LED0 for 20 milliseconds.

LED1 is turned on whenever the processor enters sleep state and turned off when woken up by an interrupt.

static void ant_channel_tx_broadcast_setup ( void  )

static

The following commands are issued in this order:

• assign channel
• set channel ID
• open channel

static

Parameters

[in]

event

The received ANT event to handle.

void PROTOCOL_EVENT_IRQHandler

(

void
