Android BLE Gatt连接更改状态

问题描述

我有一个Android应用程序可以连接到BLE设备并对其进行写入。我可以成功连接，读取和写入它。作为测试的一部分，我们正在尝试不同的断开连接方案。

I have an android app to connect to a BLE device and write to it. I can successfully connect, read and write to it. As a part of testing, we are trying different disconnection scenarions.

有时，如果设备断开连接，我会得到连接更改为 disconnect，状态值为19。此外，如果存在任何绑定错误，则状态等于22。我以编程方式断开了连接，此状态给了我0。但是在。

Sometimes, if ble device disconnect the connection, i get the connection change as disconnect with status value as 19. Also if there is any bond error, status equals 22. If i programmatically disconnect the connection, this status gives me 0. But none of these states except 0 are specified in android documentation.

发布示例BluetoothGattCallback

Posting a sample BluetoothGattCallback

private BluetoothGattCallback bluetoothGattCallback = new BluetoothGattCallback() {
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        Log.i(TAG, "onConnectionStateChange status: "+status+", newState: "+newState);
        /*i need to know the posiible values for this status variable*/
        if(newState == BluetoothProfile.STATE_CONNECTED) {
            gatt.discoverServices();
        } else {
            gatt.close();
        }
    }

    @Override
    public void onServicesDiscovered(BluetoothGatt gatt, int status) {
        Log.i(TAG, "onServicesDiscovered service discovered");
    }
};

是否有人遇到过同样的问题并整理了状态列表。我需要知道onConnectionStateChange方法中状态变量的可能值

推荐答案

这是我拥有的代码列表

• 以编程方式断开连接-0


• 设备超出范围-8


• 已通过设备断开连接-19


• 有绑定的问题-22


• 未找到设备-133（某些电话可显示62）

• Programmatically disconnected - 0
• Device went out of range - 8
• Disconnected by device - 19
• Issue with bond - 22
• Device not found - 133(some phone it gives 62)

我已经在5.0.2、5.1、6.0和6.0.1中测试了断开连接的情况。但是只有在6.0.1安卓版本中才发现了这种债券发行代码。

I have tested disconnect scenario's in 5.0.2, 5.1, 6.0 and 6.0.1. But only found this bond issue code in 6.0.1 android version.
