ANT SDM simulator

This module simulates data for the SDM Transmitter . The API for this module is available here: ANT SDM simulator

The module uses the Sensor Data Simulator to simulate automatic changes of the cadence value.

Initialization

Use the following command to initialize the module:

    const ant_sdm_simulator_cfg_t simulator_cfg = DEFAULT_ANT_SDM_SIMULATOR_CFG(&m_ant_sdm,
                                                                                SIMULATOR_STRIDE_LEN,
                                                                                SIMULATOR_BURN_RATE,
                                                                                SIMULATOR_MIN,
                                                                                SIMULATOR_MAX,
                                                                                SIMULATOR_INCR);

If you want the cadence to be changed automatically, add the following statement:

    ant_sdm_simulator_init(&m_ant_sdm_simulator, &simulator_cfg, true);

If you want to be able to change the cadence manually, add the following statement:

    ant_sdm_simulator_init(&m_ant_sdm_simulator, &simulator_cfg, false);

Including the module in an application

Periodically call the SDM simulator in the application to prepare data for each TX event occurrence. The following snippet shows how to do this:

void ant_sdm_evt_handler(ant_sdm_profile_t * p_profile, ant_sdm_evt_t event)
{
    nrf_pwr_mgmt_feed();

    switch (event)
    {
        case ANT_SDM_PAGE_1_UPDATED:
        /* fall through */
        case ANT_SDM_PAGE_2_UPDATED:
        /* fall through */
        case ANT_SDM_PAGE_3_UPDATED:
        /* fall through */
        case ANT_SDM_PAGE_16_UPDATED:
        /* fall through */
        case ANT_SDM_PAGE_22_UPDATED:
        /* fall through */
        case ANT_SDM_PAGE_80_UPDATED:
        /* fall through */
        case ANT_SDM_PAGE_81_UPDATED:
            ant_sdm_simulator_one_iteration(&m_ant_sdm_simulator);
            break;

        default:
            break;
    }
}

The following snippet shows how to change the cadence manually:

void bsp_evt_handler(bsp_event_t evt)
{
    switch (evt)
    {
        case BSP_EVENT_KEY_0:
            ant_sdm_simulator_increment(&m_ant_sdm_simulator);
            break;

        case BSP_EVENT_KEY_1:
            ant_sdm_simulator_decrement(&m_ant_sdm_simulator);
            break;

        default:
            return; // no implementation needed
    }
}
