Hi I am using android mobile application with RN171 for controlling embedded device. When I send command to the embedded device I open tcp socket with RN171 and send the command then the embedded device reply with Ack. My problem is that opening tcp Socket takes long time, so it's not comfortable for user. I decided to use udp (...)
Usually in a networking system there will be layers above Ethernet of standard protocols like IP, and further above udp, tcp and even higher than that DNS, DHCP, Telnet, HTTP e.t.c. Is there any application where only the Ethernet layer is sufficient and no standard IP layer or otherwise is used above it?
I believe that this Wikipedia chapter gives a brief answer about the difference between both protocols and a first hint when to use one or the other. To give a simple example. udp is fast, because it sends packets without confirmation on the transport layer. But you
Using enc28j60, you have to implement the tcp/IP stack in software, thus there are no specific registers for IP addresses. They have to be inserted at specific locations of the IP and tcpIP or udp frames. The chip has registers to set it's unique MAC address. A possible way is to use the Microchip tcpIP library for your (...)
You can expect effectively no packet loss in LAN operation. If at all, strong electrical interferences are the most likely cause of packet loss in a LAN. udp can be perfectly used for all protocols that transmit data as packets or messages. tcp should be used for streams or generally for data entities that exceed the capacity of an ethernet fram
Do you want to send data via SMS or tcp/udp? If it is SMS then you need to use PDU encoding if via tcp/udp then you need to use "Fixed Length Sending" as follows: Use the AT+CIPSEND= command, the data is automatically sent when the number of bytes to send is equal to the length value. There will be no > prompt
Hi All, I have done ARP and udp protocol in genesys virtex 5 kit. For the ARP request I'm getting reply from the PC. In tcp protocol, I din't get the ACK from the PC. I have tried the both ways Receive and Transmit, But PC din't respond. How to solve this problem? My question is How to get an ACK from the PC for tcp protocol. You (...)
ask your question more specifically. define your network, board, your protocol stack(physical, data link, ip,tcp). generally if you use static IP there is no need for implementing DHCP client.
there are many posts on using GSM modem to send/receive both SMS texts and tcp/udp packets do a forum search on GSM modem
Well can you please tell me the advantage of usinga phone over a GSM module for SMS alarm system? the advantage of the GSM modem is the small footprint - the aerial tends to be larger than the modem these days! if it has a tcp/IP stack one can send udp datagrams, connect to tcp servers (e.g. use FTP to download and
if the modem supports tcp/IP you could send data using udp or TDP protocols to a remote server
if your microcontroler has a network connection (e.g. ethernet or wireless) or a tcp/IP enabled modem you could use tcp protocols to access the database
Switch and hub hub was the first generation of tcp/udp protocol , it divides the bandwidth between the stations connected to the network through the hub then comes the switch: it has a high speed backbone bus to accomplish full bandwidth data rate for clients,for your example if the station is 100 Mb/s all of them will transfer data with the same s
Ok, here is the idea. I want to use my Raspberry Pi as a server between PC application and microcontroller. Microcontroller unit will do some stuff and communicate with raspberry Pi via UART and Raspberry Pi will comunicate with PC application via tcp/IP or udp protocol (Accesible over WWW). Also, I want my raspberry Pi to act as a interface betwee
Which IP you want to send data ?? and there are some modes by which you can send data through GSM (like SIM900), tcp , FTP , udp SO first decide by which way you want to send data !!
r u using ucp or tcp? are you using socket programming apis to communicate? or what is the procedure you are following for data transfer?
Hi, I have a couple of ip cameras everyone of which can be operated either in tcp mode or udp mode but i could not find how to adjust them to udp. There is not such a choice in the setting sections. I need support from a network authority :). Thanks in advance,
Hi, I want to implement packet classification based on ETHERNET/IP/udp/tcp packets. So during search I found that CAM core can be used for classification. But it has limitation that it can not classify range of data which is main thing for classification in design. Is there any possible solution for this? If there is, please suggest. I'm
Hi, I want to know more about Industrial ethernet that uses udp. I know something about ethernet and udp/tcp protocols. I need to know how a PLC can address devices that uses this protocol ? In PROFIBUS a gsd file is used to specify addresses to registers on the slave device, so that a PLC can address the device correctly. A (...)
Hi. I am using SIM900 Module. I like to have your suggestion regarding GPRS communication: -1. For periodic Data send (tcp/udp) with an interval of 5 or 10 sec which method will be good choice - Data (Transparent) Mode or Command Mode? -2. Is there any way to automatic switch from Data Mode to Command Mode when SMS or Voice Call comes (wi
Hi, this is my first post in this I have to design a very simple a device with the connectivity of Ethernet. It just want to send an udp packet to my Server with few bits of data. I have a PIC18F452 and a ENC28J60. I gone through the tcp/IP stack and SPI Ethernet ENC28j60 library. Both of these web sites are saying those librar
Hello, I am using microchip tcpip stack with explorer 16, fast ethernet pictail with ENC624J600 and pic32. I want to send and receive data from pic to pc and from pc to pic first using just the udp and then using just the tcp. Can anybody tell me any good lead to start with, tips or any demo or test code for udp or (...)
hello all! i am an intermediate in FPGA field and working on spartan3e starter kit. my task is to implement ethernet communication for tcp/udp communications using Microblaze. i have surfed the net and found many data regarding that but in am confused and not been able to get a start and direction in progress. can any one direct me that
there are several options. 1. Implement a tcp/IP stack and use the FTP protocol to transfer files to the sdcard. This method may seem cumbersome but since you have a ethernet port on the system a tcp/IP stack may be the best solution. 2. Instead of implementing tcp protocol, which is quite complicated, you could use udp (...)
Yes , you can I tested that by myself It was raw communication without tcp/IP , udp ... headers Here's the sample code for LPC1768 on IAR and Uvision4
It's a convoluted way of saying that you want to know about how to interface to Ethernet, and about how to communicate over Ethernet, using microcontrollers. Look at (say) ENC624J600 for the former, and read up on udp and tcp for the latter. With this information, you can achieve your aim mentioned in your post. You can download an IP stack for yo
Hi, Wish you all a nice day. I'm asking how tp adapt to tcp/ip application (telnet )in the DE2-115 board to an udp/ip application and what kind of application can I do with udp in the FPGA. I'm looking for a huge traffic to compare it with the hardware implementation of udp any idea or suggestions or tutorial (...)

you could use tcp or udp to send the patient data to a tcp/udp server which could then be viewed via a secure web page
I use the Sierra Wireless AirLink Fastrack Xtend FXT009 it supports a tcp/IP stack so can be used for embedded microcontrollers to log data to tcp and udp servers (also supports FTP, HTTP, SMTP, POP3, etc)
use tcp or udp sockets, e.g. tcp
Hello Bigdog, Thanks for your reply. To what microcontroller and stack source are you referring? BigDog I am using PIC24FJ128GA010 MCU with Explorer-16 Board. And I am using tcp stack version v5.10 and C30 compiler. And ZG2100 wi-fi module. Want to know how to send data packets using udp to the remote router.
It is a tool for test tcp Server, tcp Client, udp Server, udp client, free use. android mobile or notebook can use,scan to
I aim to write a Visual C++ code that would receive rs-232 data from com port..perform AES 128bit 16rnds encryption..and then send the encrypted data over the ip using udp (or maybe tcp). the reverse would be performed at the client end. Please provide guidance on how to start.
Hi, Wish you all a nice day. We need to send data from one transmitting board to two receiving boards, we are connecting them via Ethernet using tcp/IP protocol. We connect the three boards as attached, but it was found that it is necessary to connect both the transmit and receive pins in the second receiving board to the receive and trans
I want make a webserver on the board of stm32,but i don't know how can i output the data to the web! I us the uip1.0 for the tcp/ip protocol stack.
If it is tcp/IP enabled you could tcp or udp to transfer information to a remote server. Some tcp/IP enabled modems even have an FTP application.
will release a core that meets your requirements this month. The COM-5402SOFT tcp/udp/IP stack core for Spartan-6 (no external RAM, standard MAC interface) is written in VHDL and includes all the source code. Speed is 1 Gbps running at 125 MHz processing clock. The optional lower layer (MAC) core is available now. The specifications ar
What is you PHY going to be like? Also, since you don't care about udp or tcp, you could also consider raw ethernet frames. Depends a bit on what the spartan-6 is going to connect to. If it for example a direct utp cable to a PC that you have full control over (i.e no routing/switching), then you could do raw ethernet. That would mean less effort f
If you modem is tcp/IP enabled it can support HTTP or FTP. However, unless the modem manufacturer can provide a HTTP or FTP application (I have seen FTP for Wavecom modem) or there is a third party supplier you will have to write you own. I tend to write my own tcp or udp client/server applications for modems.
what exactly is your problem - are you missing tcp/udp packets ? how much traffic is there? I have used a PIC18F97J60 (which has an onboard Ethernet controller) with various devices attached (LCD, LEDs, barcode reader, RTC, IO extenders, etc) without problems. However, the traffic was low consisting of a data udp packet transmiited every (...)
I thought the SIM300 was a GSM modem? Assuming a GSM modem to could send GPS coordinates using an SMS text message or, if the modem has tcp/IP support, using tcp virtual circuit or udp datagrams
for variaous project where we send data to mobiles or servers we have used the WISMO 228 Sierra Wireless - WISMO228 GSM/GPRS module for M2M you can send text messages to mobile phones or use tcp or udp to send data over tcp/IP to remote serve
if you are working on a radio controlled car why not talk to it directly using WiFi ? all modern laptops are equiped with WiFi. The car could be equipend with a microcontroller with a WiFi interface and you could write a VB program to send tcp or udp packets to the car. Are you also going to write the code for the car or is someone else doing tha
There's no standard for RS232 over IP transmission, you have to refer to the product documentation. Usually, a manufacturer provides drivers to set up a virtual COM port connecting to the device, this is a least the case for industry standard products from Lantronics or Moxa. Most products have the option to configure a raw tcp or udp link, but you
If you want to be 100% sure about getting no errors, you will need to implement some sort of CRC. udp as such is not enough, but can be used a carrier protocol to implement your data check. An other way is to implement a full tcp/IP stack. this ensures error free data transmission. Regards, L

Look at the FAQ's on this page . The FAQ on making a GPRS connection shows a tcp connection, but udp uses the same commands, just replace "tcp" with "udp". And When asked to define PDP context ... wat is cid and PDP type? The PDP Context is a data structure that contains the subscriber session
