You can have a look at the ant_background_scanning example.

See application_initialize(). To get ANT to pass the Device ID (device number, device type and transmisson type) you can use the following library configuration:

/* Set library config to report Device ID */
uint32_t err_code = sd_ant_lib_config_set(ANT_LIB_CONFIG_MESG_OUT_INC_DEVICE_ID);
APP_ERROR_CHECK(err_code);

See background_scanner_process(). When you get the EVENT_RX event, you can get the device number with

uint16_t device_id = (uint16_t)(p_ant_message->ANT_MESSAGE_aucExtData[0]
                   | ((uint16_t)p_ant_message->ANT_MESSAGE_aucExtData[1] << 8));

and transmisson type with

uint8_t trans_type = p_ant_message->ANT_MESSAGE_aucExtData[3];
