This information applies to the following SoftDevices: S210, S310

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 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_RX_ONLY

CHANNEL_TYPE_MASTER
