kandi X-RAY | zeroconf Summary

zeroconf is a C++ library typically used in Networking applications. zeroconf has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

The idea behind MDSN discovery is to allow client applications to find IP addresses of their server counterparts by sending a query to broadcast address (255.255.255.255). MDNS client and servers talk to each other by UDP, using packet format similar to generic DNS. The approach is widely used with Apple and IoT devices. The mainstream implementations of MDNS are Avahi and Bonjour. While doing good job in most scenarios, they are not uniformly available, or might just be too heavy to bundle for the sake of one simple call. This library comprises a cross-platform and very light MDNS client. It's implemented against both Posix sockets and Winsock using header-only approach.

Zeroconf is about letting a client find a service and which port to connect to, not the actual data transmission. There are tutorials on the net about creating simple clients and servers in python. Here is one Python socket programming.

Don't use DISTRO_FEATURES += because the default is a ?= assignment. Use DISTRO_FEATURES_append = " x11 systemd"

Same for IMAGE_INSTALL. The default is a += assignment, so what you're doing is creating an image that just contains the sato-games and nothing else.

Pulseaudio setting up sinks and sources for A2DP and HFP connections

Asked 2019-Jun-13 at 09:32

I'm trying to set up A2DP+HFP profiles in an embedded board. Goal is to use pulseaudio 12.2, ofono 1.18, and bluez 5.41 in order to connect to a mobile phone and use A2DP, HFP profiles automatically, whenever necessary. I did lots and lots of things to update the versions and configure the daemons. Right now I can see that HFP profile is available when connected.

A2DP works perfectly and I am able to stream music from phone to embedded board. When I get a call, I can answer it with Bluetooth and it looks that HFP is the active profile whilst I'm in the call. The weird thing is that there is no audio from the embedded board (HDMI monitor connected to it).

The following will give you how it looks like. When I'm streaming music from phone via A2DP, I get following sources and sinks:

To get the IP addresses, you can use the attribute address of class ServiceInfo. It gives you the IP address in bytes type (in your post, it is displayed as b'\n\x80Cj'), so that you should use socket.inet_ntoa() to convert it to a more readable format. Here is the code where I replaced the print() instruction in the MyListener.add_service() method in order to print the IP address:

The C# IDE has an option for that, "Specific Version = False". Not available in the C++/CLI IDE. Frankly, this is not a real problem. You are probably using the [AssemblyVersion] attribute incorrectly. That version is associated with the publicly visible classes in the assembly. If you make any changes in the public members of those classes then you've got a potentially breaking change that can make code that has a dependency on those classes fail.

At that point should you change the [AssemblyVersion]. And any project that uses the assembly must get their reference assembly updated and must be recompiled.

An otherwise non-breaking change, like a bug fix or a tweak in the non-visible classes produces a new file that is otherwise completely compatible with any project that uses it. You should update the [AssemblyFileVersion] number. Which in a C++/CLI project requires updating the unmanaged Version resource. Changing the corresponding .rc file could be automated, or you could use a #define.

Note how the .NET base assemblies in version 2.0 behaved the same way. Their [AssemblyVersion] stayed at 2.0.0.0 throughout the 3.0, 3.5 and 3.5 SP1 releases. Their file version started at 2.0.50727.42. And got incremented many times over the past 5 years, up to 2.0.50727.4927, give or take.

For the record, that VS2010 bug you linked to is not a bug. It just never worked before, failure was silent. It is a flaw in the C++ build system, mt.exe embeds the manifest after the assembly is strong named. And breaks the strong name in the process because that changes the file hash. VS2010 is actually an improvement, it warns about it rather than silently letting a broken strong name go through. You don't have to delay-sign, only resign with -Ra in a post build event.

QUESTION

zeroconf on wireless connection without password

Asked 2018-Nov-10 at 14:43

I want to setup a register / discover type of service connection between 2 devices on the same wireless LAN. Idea is to find, connect and send wireless router password to a new device for easy installation. This needs communication between 2 devices on the same wireless network before connecting to router with SSID, password.

I'm aware of zeroconf, bonjour and mDNS libraries. All implementations I see start with connecting to wifi in station mode to get a local IP with hardcoded SSID and password, which is not known at this stage.

In other words, how can connect to wireless and get a link local IP without SSID and password?

-- Edit for better explanation --

The flow i'm looking for is like this:

1- Mobile phone (iphone or android) is connected to secure home wireless network as usual
2- A new device with wireless interface is powered on first time.
3- Device gets (or sets) a local IP and local dns name (multicast ip and name) for itself
4- Device broadcasts its available services to the network
5- Phone discovers the service, along with devices' local name and even local ip already assigned.
6- Phone initiates a direct connection with the device to send wireless configuration information (ssid and password for the access point)
7 - Device saves this information, resets into normal operation mode
8 - Device connects to internet
9 - Device services are still available in the local network

-- edit --

Code will run on esp32 or esp8266, so compatible c or arduino libraries are ok.

I'm aware of smartconfig implementation of ESPTouch application, but it is a horrible design! Discovery program tries to create sockets to every possible IP address to find the peer IP.

Read this sentence in your question again and think about it:

The protocols you mentioned are only possible AFTER you're part of the network. As you know, wifi networks are protected to prevent unauthorized access.

Try wifi protected setup (WPS) in Google.
