Migration from dbus to GDbus in Python 3

由 我的未来我决定 提交于 2020-03-03 08:10:36
问题 I have tried to write a service file in python using GDbus. But I could not find a good tutorial, only if i want to use C. Since I want to include GDbus in an existing Python code i have no idea how to do that. It was possible for me to write a service file using dbus and I could access that service file with a GDbus client. I would be very happy if somebody had a good example in Python. Thanks a lot, Dominik 回答1: While you can use GDBus from Python, it might not be the nicest (most Pythonic)

Sending a byte array (type `ay`) over D-Bus using GDBus

由 怎甘沉沦 提交于 2020-01-01 10:12:57
问题 I am trying to a byte array over D-Bus using the GDBus bindings. Can you please let me know how I can achive that. I tried googling but didnt help. Byte array contains a image file so cannot be converted to charbytearray Any help is appriciated 回答1: This question has some good ideas in the answers including for passing large amounts of data by writing the data to a file and passing the filename, or using a named pipe. Writing to a file and passing the file name might be the easiest to

gdbus-monitor - interface `<none>`

由 瘦欲@ 提交于 2019-12-25 07:08:02
问题 Has the interface <none> in the gdbus-monitor output a special meaning? What API call is required to create such a message using GDbus ( g_dbus_connection_register_object does not allow to pass NULL as GDBusInterfaceInfo * and that seems to be the only to register a object to a path) related: dbus - register object to remote on interface NULL 回答1: Looking into dbus-monitor 's source code shows that it occures as soon as DBUS_EXPORT const char * dbus_message_get_interface ( DBusMessage *

dbus - register object to remote on interface NULL

由 可紊 提交于 2019-12-25 04:09:06
问题 I have to deal with a binary blob dbus service/server which I need to connect to via dbus (session). The introspection of the interface is as following (obtained via gdbus-codegen ). We register a function to the remote so we get notified if a message has been received by the remote which is called message_handler . That happens as a response on a send_message command which I pass via dbus, but that works (and is thus not shown). In a java example it is done via dbus_connection.exportObject("

QDBus与gdbus的数据传递详解

由 a 夏天 提交于 2019-12-06 08:10:05
在Linux平台的进程间通信多了一个dbus技术，应用还是非常广的，其中有一个应用模式是采用gdbus实现相关业务逻辑，采用QtService调用qdbus暴露出服务给客户使用。这种模式还是非常便捷的。不过QDBus和gdbus相关资料还请自行查找。这里只是针对他们的数据传递（函数的参数）进行详解。 1，框架的建立 首先我们需要根据业务需要建议一个xml文件hello.xml，描述interface以及包含的函数等信息，比如： <?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="introspect.xsl"?> <node xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="/org/alibaba/kenton" xsi:noNamespaceSchemaLocation="introspect.xsd"> <interface name="org.alibaba.kenton.hello"> <version>1.0.0</version> <doc> <line>This is a test interface</line> </doc> <method name="GetVersion"> <doc>

BlueZ 5.30: D-Bus GATT API - Simply Discover and Connect to a BLE device in C

由 风流意气都作罢 提交于 2019-12-03 10:08:42
问题 With the last release of BlueZ (5.30) the highlight was the completion of the GATT D-Bus apis. My goal is to programmatically (in C), as a BLE client: scan for ble devices (which I can do with the hci layer) Connect to an advertising BLE device Get the UUIDs Execute Read and Write to handles The BlueZ community is strongly suggesting to use the GATT-Dbus api to accomplish this. After multiple searches and head scratching I was not successful to find a proper way or example that would perform

It seems more complicate than just use directly the GATT layer.
