重新连接BLE

Question

我们有一个使用BLE连接的设备。

第一次连接成功。

但是当信号丢失时，重新连接不会发生

连接：

ble.connect (deviceAddress, connectSuccess, connectFailed);

如果连接成功，我会向按钮添加一个事件

function connectSuccess (characteristic) {
    log ("connectSuccess to" + characteristic.name);

    var fieldState = document.getElementById ("fieldState");
    fieldState.addEventListener ("click",
        function () {readData (uuids1.StateState, "field State", "textField"); });
}

当连接失败时，我每隔10秒询问一次设备

function connectFailed (characteristic) {
    log ("connectFailed to" + characteristic.name);
    ble.disconnect (deviceAddress);
    reconnect = setTimeout (function tryToBack () {
        ble.connect (deviceAddress, sc, connectFailed);
        log ("Try Connecting !!");
        reconnect = setTimeout (tryToBack, 10000);
        },
    100);
}

function sc (data) {
    clearTimeout (reconnect);
    log ("Success reconnect to" + data.name);
    log ("with address" + deviceAddress);
    connectSuccess (data)
}

但是当设备在视线中时，它已连接但没有响应按钮点击。
