错误 1359 设置蓝牙无线电模式 Windows Embedded Handheld 6.5

Question

将In The Hand 32feet library 用于.NET Compact Framework 3.5，在运行Windows Embedded Handheld 6.5 Professional CE OS 5.2.29366 Build 29366.5.3.12.48 的Datalogic Sc​​orpio X3 上运行他们的示例项目Chat2Device 时，切换蓝牙无线电的命令“可发现”失败。我添加了一些额外的错误报告代码，发现本机错误代码是 1359 (Internal Error Occurred?)

在移动设备上的此示例项目中使用蓝牙的设备之间通信没有问题，仅检索 PrimaryRadio 信息或尝试将 RadioMode 设置为任何模式都会引发异常。

完整的错误信息是：

Win32异常 在 InTheHand.Net.Bluetooth.Msft.WindowsBluetoothRadio.set_Mode（RadioMode 值）设置 BluetoothRadio 错误代码 1359 时出错

代码是：

BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable;

示例中的以下代码也因类似异常而失败：

var myRadio = BluetoothRadio.PrimaryRadio;
            if (myRadio == null) {
                wtr.WriteLine("No radio hardware or unsupported software stack");
                return;
            }
            var mode = myRadio.Mode;
            // Warning: LocalAddress is null if the radio is powered-off.
            wtr.WriteLine("* Radio, address: {0:C}", myRadio.LocalAddress);
            wtr.WriteLine("Mode: " + mode.ToString());
            wtr.WriteLine("Name: " + myRadio.Name);
            wtr.WriteLine("HCI Version: " + myRadio.HciVersion
                + ", Revision: " + myRadio.HciRevision);
            wtr.WriteLine("LMP Version: " + myRadio.LmpVersion
                + ", Subversion: " + myRadio.LmpSubversion);
            wtr.WriteLine("ClassOfDevice: " + myRadio.ClassOfDevice
                + ", device: " + myRadio.ClassOfDevice.Device
                + " / service: " + myRadio.ClassOfDevice.Service);
            wtr.WriteLine("S/W Manuf: " + myRadio.SoftwareManufacturer);
            wtr.WriteLine("H/W Manuf: " + myRadio.Manufacturer);

有关修复的任何建议，或将无线电设置为以编程方式可发现的替代方法。

    }

我不确定带有 WEH65 的“Datalogic Sc​​orpio X3”，但有些设备带有非 MS 蓝牙堆栈。

AFAIS，“Datalogic Sc​​orpio X3”SDK 提供了用于控制蓝牙的独特 API 集。

设置BT模块模式的标准函数是BthSetMode。另一个函数BthWriteScanEnableMask 被32feet 使用。这可能没有在 Datalogic X3 上实现。
