android - 自治 DFU 北欧

Question

我正在开发连接到 BLE 设备的应用程序，我专注于设备的固件更新 (DFU)。为此，我正在使用由 Nordic 创建的 android lib，并且我正在尝试使其自主，因此用户不必浏览他的文件并选择固件更新的 zip。

但是，DFU 总是停在 30%，应用程序失去了蓝牙连接，我必须使用外部应用程序手动完成更新。

有没有人已经用 DFU 做过这种事情并且可以帮助我？

这是 lib 的 github 的链接：https ://github.com/NordicSemiconductor/Android-DFU-Library

这是我目前正在使用的代码，它是带有适用于 Android 的 Nordic lib 的标准 DFU 程序。

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：这里有一些日志显示运行时发生的情况
