OSDK遥测数据订阅频率怎么设置

关键词：遥测订阅，频率设置

OSDK 遥测数据的订阅频率只能通过initPackageFromTopicList中的freq参数进行设置。

例如：

// Package 0: Subscribe to flight status at freq 1 Hz
int pkgIndex = 0;
int freq = 1;
TopicName topicList1Hz[] = { TOPIC_STATUS_FLIGHT, TOPIC_GPS_POSITION, TOPIC_GPS_DETAILS};
int numTopic = sizeof(topicList1Hz) / sizeof(topicList1Hz[0]);
bool enableTimestamp = false;

bool pkgStatus = vehicle->subscribe->initPackageFromTopicList(
pkgIndex, numTopic, topicList1Hz, enableTimestamp, freq);

广播频率设置：

 // Re-set Broadcast frequencies to their default values
ACK::ErrorCode ack = vehicle->broadcast->setBroadcastFreqDefaults(TIMEOUT);
