我正在开发连接到BLE设备的应用程序，并且专注于设备（DFU）的固件更新。为此，我正在使用Nordic创建的android lib，并试图使其具有自治性，因此用户不必浏览其文件并选择固件更新的zip。
但是，DFU总是停在30％的位置，该应用失去了蓝牙连接，我必须使用外部应用手动完成更新。
有没有人已经用DFU做过这种事情并且可以帮助我？
这是指向lib的github的链接：https://github.com/NordicSemiconductor/Android-DFU-Library
这是我当前正在使用的代码，这是Nordic lib for Android的标准DFU过程。
val starter = DfuServiceInitiator(deviceMacAddress!!)
.setDeviceName(deviceName)
.setKeepBond(true)
starter.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true)
starter.setZip(uri)
val controller = starter.start(context!!, DfuService::class.java)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
DfuServiceInitiator.createDfuNotificationChannel(context!!)
}
编辑：以下是一些日志，显示了运行时发生的情况
