This information applies to the following SoftDevice: S212

This module indicates the state of the assigned ANT channel. The API for this module is available here: ANT channel state indicator

During initialization, the module links signalling with the selected channel.

Initialization

The Board Support Package (BSP) must be initialized before initializing this module, so that Board-specific indications and states can be used.

The following code example shows how to initialize the module:

        uint32_t err_code;
       

       

        APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE,
        
         false
        
        );
       

        err_code =
        
         bsp_init
        
        (BSP_INIT_LED,
        
         APP_TIMER_TICKS
        
        (100, APP_TIMER_PRESCALER), NULL);
       

        
         ant_state_indicator_init
        
        (CHANNEL_NUMBER, CHANNEL_TYPE);
       

       

        err_code =
        
         sd_ant_channel_open
        
        (CHANNEL_NUMBER);
       

        
         APP_ERROR_CHECK
        
        (err_code);
       

       

        err_code =
        
         ant_state_indicator_channel_opened
        
        ();
       

        
         APP_ERROR_CHECK
        
        (err_code);
       

Propagating ANT events to the module

The application should propagate ANT events to this module. The following code example shows how to do this:

        
         void
        
        ant_evt_dispatch(
        
         ant_evt_t
        
        * p_ant_evt)
       

        {
       

        
         /*
        
       

        
         Other calls.
        
       

        
         */
        
       

        ant_state_indicator_evt_handle(p_ant_evt);
       

        }
       

Indications

Depending on the type of channel, the module indicates states in different ways.

CHANNEL_TYPE_SLAVE/CHANNEL_TYPE_SLAVE_RX_ONLY

CHANNEL_TYPE_MASTER
