EPO文件更新

11.1功能概述

EPO是辅助全球卫星定位系统，指的是一种GPS的运行方式。它可以利用手机基地站的资讯，配合传统GPS卫星，让定位的速度更快。需要注意的是EPO文件更新:手环连接App15秒后，查询GPS状态未运行更新EPO文件，否则会导致更新失败。

11.4 EPO更新方法

Objc:

// Step 1,  determine the functionTable and see if it supports EPO upgrade
        if (!__IDO_FUNCTABLE__.funcTable34Model.supportAirohaGpsChip) {
            NSLog(@"This device does not support EPO upgrades");
            return;
        }

// Step 2, check if the EPO update exceeds 24 hours, and if it exceeds 24 hours, an update is required

        //The general EPO update time is more than 24 hours before it needs to be updated
        // gpsManager.updateTime = 24; default
        IDOGpsManager*gpsManager = [IDOGpsManager shareInstance];
        if (![gpsManager startCheckoutOnlineAgpsEPOIsNeedUpdate]) {
            NSLog(@"EPO files cannot be operated during this time period");
            return;
        }

// Step 3, download the EPO upgrade file
        [gpsManager downLoadEPOFile:^(IDOGpsUpgradeType status, NSString * _Nonnull epoFileFolder) {
            if (status == IDOGpsUpgradeTypeSucc) {
                self.filePathFolder = epoFileFolder;
                NSLog(@"download successfully");
            }else{
                self.filePathFolder = nil;
                NSLog(@"download failed");
            }
        }];


//Step 4, make the downloaded files from Step 3 into EPO files that can be upgraded  

        if(self.filePathFolder.length <= 0){
            NSLog(@"download EPO file");
            return;
        }
        self.epofilePath = [IDOGpsManager getMakeGpsZipFileWithFilePath:self.filePathFolder];

//Step 5, transfer the EPO file to the watch device

    initTransferManager().transferType = IDO_DATA_FILE_TRAN_DIAL_TYPE;
    initTransferManager().compressionType = IDO_DATA_TRAN_COMPRESSION_NO_USE_TYPE;
    initTransferManager().fileName = @"EPO.DAT";
    initTransferManager().isSetConnectParam = YES;
    initTransferManager().isQueryWriteState = NO;
    initTransferManager().filePath = self.epofilePath;

    __weak typeof(self) weakSelf = self;
    initTransferManager().addDetection(^(int errorCode) {
        if errorCode == 0{
           //Detection succeeded before update
        }else {
         //Detect errors before updating 
        }
    }).addProgress(^(int progress) {
       //Update file progress（0-100）
    }).addTransfer(^(int errorCode,int value) {
        if errorCode == 0 {
           //File transfer succeeded
        }else {
          //file transfer failed
        }

//Step 6, after the EPO upgrade is successful, update the EPO update time

        if (errorCode == 0) {
            self.filePathFolder = nil;
            [[IDOGpsManager shareInstance] updateAgpsEPOFileUpdateTimeNow];
        }
    });
    [IDOTransferFileManager startTransfer];
