TCP-Connect | Pre-release for TCP Bulbs | Continuous Deployment library

I am doing Spring Integration with Server and Client request/response demo. The request comes with a Byte array which is to be converted to Object. Then the request comes to the input channel, I need to check which class is to be send to the service activator. Then the service activator will send it to the reply channel.

I am new to spring integration and currently stuck on unit testing my integration flow. My flow looks something like this.

1. Recieve some data from TCP channel adapter in XML format.
2. Convert it to JSON.
3. Send JSON message to amazon sqs queue.

and XML file is :

I'm want to implement an API beetween Prolog and MongoDB and after some research the first hurdle would be connecting to MongoDB server. I know there's allready the API prolongo so I tried to understand it, but I don't. I'm a newbie in Prolog so my question is: Where is the actuall connect to the MongoDB server?

Edited: I've understood more of the code but I'm getting an error, that I can't interpret:

So here's the code of the mongo_connection.pl:

please, Can you help me?
All of source here it is.

Thank you.

1. I created a spring integration-tcp-client context xml file.

We have the following configuration: Server, Client, DHCP-Server. The server runs on a static IP in "client mode". This means, that server has a list of all clients (hostnames) and builds TCP-connections. Clients have dynamic IPs.

How does it working: 1) Server creates a connection to a client and 2) Server waits for any data from a client (we use ACE framework and reactor-pattern). To have the list with clients up to date, we have added an additional timer, that sends a heartbeat to all clients.

And there is one strange behavior: let's say a hostname "somehost.internal" has IP "10.10.100.50"

1. Time = t: connect to hostname "somehost.internal"
2. Time = t+1: change IP of the client to "10.10.100.60"
3. Time = t+2: heartbeat timer send data to an existing endpoint (10.10.100.50) and successfully returns (why??? this IP is not accessible)
4. in Wireshark I can see, that Retransmission packages
5. Time = t+5: some seconds later event handler returns with an error and the connection to the endpoint (10.10.100.50) will be closed

Do you have any advice, why a blocking send-function successfully returns when remote endpoint does not exist anymore?

I'm playing around with a ZYNQ7 (Dual-Core ARM) with a FPGA. The FPGA design has a 32-bit counter accessing the DDR via a DMA controller in chunks of 256-packets.

In the C-Code for the processor 1, I run a LWIP application to connect via ethernet to my pc. There I allocate ram memory for the DMA transactions. The address of the pointer is passed via shared memory to the 2nd Core.

This post is related to ROS (Robot Operating System) and ESP8266, and has also been cross-posted on ROS Answers and Robotics Stack Exchange.

I've ROS Melodic running on a Raspberry Pi 4 and need to send out information (as strings) over wifi to multiple ESP8266. I'm only just starting so it's just one ESP8266 for now. For communication, I'm using socket_node found in the ROS package rosserial_server (package wiki).

Referring to the picture below, the slave node publishes to the topic /Topic_data_over_wifi which is subscribed by a node running on the ESP8266:

The problem is, the node /rosserial_server_socket_node remains floating!

I've double checked names of topics and IP addresses, and at one point, got the node /rosserial_server_socket_node to actually link to the rest of the ROS network as shown in the "What I want" section. However, that was just one time (a fluke?) and never could I again get /rosserial_server_socket_node to join the ROS network.

rosserial_server's socket_node is used with its default settings (port 11411). I did try other port numbers but there was no difference. After all nodes have been launched, here's the output of rostopic list (other than the usual /rosout and /rosout_agg):

• /commands_from_master_node
• /topic_data_over_wifi

Goal: I need to find a way to connect the ESP8266 and the Raspberry pi 4 over wifi using ROS. More specifically, I need to get data from the slave node (on Raspberry Pi) to the node running on the ESP8266.

I've already looked at this multiple-TCP-connections post but didn't find anything that could solve my problem.

Any inputs/suggestions will be very appreciated.

I am working on a high-volume integration with using spring integration tcp and I only send a request and receive more than millions of data over one connection and the time between two receiving message is lower than 100 milliseconds.

Here is my context xml and I am using TCPOutboundGateway.

I need some help with a migration to Spring Integration. Actually we have a component based in java.net package, it includes only a few classes with a java classic TCP Client, nothing fancy, that actually works to send some requests to a legacy server by tcp. This is the code for sending and receiving a message:
