Background scanning ?

[RixtronixLAB]

Dear Members,

For scanning GSC10 sensor,

can this example be used ?

Thanks

A what ?

[RixtronixLAB]

Garmin GSC10 , can I retrieve the information from it with ANT background scanning ?

How can I use this function ?

void background_scanner_process(ant_evt_t * p_ant_evt, void * p_context)
{
    uint32_t err_code;
    UNUSED_PARAMETER(p_context);
    if (p_ant_evt->channel != ANT_BS_CHANNEL_NUMBER)
    {
        return;
    }

    switch (p_ant_evt->event)
    {
        case EVENT_RX:
        {
            err_code = bsp_indication_set(BSP_INDICATE_RCV_OK);
            APP_ERROR_CHECK(err_code);

            if (p_ant_evt->message.ANT_MESSAGE_stExtMesgBF.bANTDeviceID)
            {
                m_last_device_id = uint16_decode(p_ant_evt->message.ANT_MESSAGE_aucExtData);
            }

            if (p_ant_evt->message.ANT_MESSAGE_stExtMesgBF.bANTRssi)
            {
                m_last_rssi = p_ant_evt->message.ANT_MESSAGE_aucExtData[5];
            }

            NRF_LOG_INFO("Message number %d", m_recieved);
            NRF_LOG_INFO("Device ID:     %d", m_last_device_id);
            NRF_LOG_INFO("RSSI:          %d", m_last_rssi);

            m_recieved++;
            break;
        }
        default:
        {
            break;
        }
    }
}

background_scanner_process(ant_evt_t * p_ant_evt, void * p_context)

What value should I enter in that (ant_evt_t * p_ant_evt, void * p_context) ?

Thanks

Do I need to include these ;

#ifndef ANT_PLUS_NETWORK_KEY
    //#define ANT_PLUS_NETWORK_KEY    {0, 0, 0, 0, 0, 0, 0, 0}            /**< The ANT+ network key. */
        #define ANT_PLUS_NETWORK_KEY {0xB9, 0xA5, 0x21, 0xFB, 0xBD, 0x72, 0xC3, 0x45}
#endif //ANT_PLUS_NETWORK_KEY

#ifndef ANT_FS_NETWORK_KEY
//    #define ANT_FS_NETWORK_KEY      {0, 0, 0, 0, 0, 0, 0, 0}           /**< The ANT-FS network key. */
        #define ANT_FS_NETWORK_KEY      {0xA8, 0xA4, 0x23, 0xB9, 0xF5, 0x5E, 0x63, 0xC1}           /**< The ANT-FS network key. */
        
#endif // ANT_FS_NETWORK_KEY

How can I display :

            NRF_LOG_INFO("Message number %d", m_recieved);
            NRF_LOG_INFO("Device ID:     %d", m_last_device_id);
            NRF_LOG_INFO("RSSI:          %d", m_last_rssi);

This is a callback event from the softdevice to handle ANT events, that is registered by:

NRF_SDH_ANT_OBSERVER(m_ant_bs_observer, ANT_BS_ANT_OBSERVER_PRIO, sf_background_scanner_process, NULL);

For instance depending on the ANT event (p_ant_evt->event) you may choose to handle the data attached to the event depending on your application.

[Kenneth]

The defines (ANT_PLUS_NETWORK_KEY and ANT_FS_NETWORK_KEY) are required if you plan to support or develop an ANT+ profiles. You can find various ANT+ profiles on www.thisisant.com depending on the application.

If I want to see the value of Garmin GSC10 cadence and speed sensor, how can I retrieve it ? thanks

Hi Kenneth,

Please give me suggestion, which example should I use for scanning Garmin GSC10 ?

Thanks
