Android Bluetooth IOException: в соединении отказано

Примечание: также опубликовано на https://groups.google.com/forum/?fromgroups=#!topic/android-scripting/UsPy3x4jvG0

Я пытаюсь подключиться к устройству Bluetooth RFCOMM. Я использую sl4a и подключаюсь из скрипта Python. У меня есть два устройства Android с одной и той же версией Android 2.3.4.

На одном устройстве (Galaxy S2 с ядром, очень близким к стандартному, с рутом) скрипт работает нормально и подключается к устройству RFCOMM. На другом устройстве, экзотическом Winmate E430T (подозреваю, что это специализированный защищенный телефон Android с довольно низким уровнем громкости), я получаю java.io.IOException: Connection refused.

Я безуспешно пытался запустить пример кода bluetooth_chat.py, он предназначен для подключения Android к Android. Я получаю то же сообщение об ошибке, которое указывает, что проблема не в моем коде, а скорее в состоянии телефона Winmate (рутирован или нет, установленное ПО, конфигурация).

Кто-нибудь видел что-то подобное? Я видел сообщения о непарном восстановлении, я пробовал это дважды, но это не помогло. Я также попытался перезагрузить Winmate после установки Python и всех модулей.

Код:

import android
droid = android.Android()
address = '00:12:F3:11:DC:D5'
uuid = '00001101-0000-1000-8000-00805F9B34FB'
droid.toggleBluetoothState(True)
droid.bluetoothConnect(uuid, address)

Редактировать 09.13.2012 09:55: Попробовал Bluetooth Chat App (БИЛЛ РЭЙ) с маркета и он позволяет моим двум телефонам общаться, я могу подключиться с любой стороны: проблему можно решить хотя бы на Яве. Тем не менее пример bluetooth_chat.py не работает.

Редактировать 10:45: я пробовал из BeanShell все еще в SL4A с той же проблемой, работает на моем S2 и не работает на моем Winmate:

код:

source("/sdcard/com.googlecode.bshforandroid/extras/bsh/android.bsh");
droid = Android();
droid.call("makeToast", "Hello, Android!");
address = "00:12:F3:11:DC:E5";
uuid = "00001101-0000-1000-8000-00805F9B34FB";
droid.call("toggleBluetoothState","True");
droid.call("bluetoothConnect",uuid, address);
droid.call("makeToast", "Bye, Android!");

Не работает ли случайно неисправный WinMate под управлением Android ICS? 4.0.x я думаю. - Radu 30.10.2012

В проекте Python4Android есть копия PyBluez, скомпилированная для ARM, которая может быть полезна. здесь.

Это не чистый Python, но установить его несложно; вы просто загружаете копию файла яйца на свой дроид, открываете приложение Python4Android, нажимаете «Импортировать модули» и выбираете файл яйца.

Я использовал этот материал раньше без проблем.
