#43436 Experimental Drivers for Wiznet-based Ethernet Shields

Posted by VladVictor on 15 January 2013 - 10:27 AM in Beta Firmware and Drivers

For example i send 3 strings of data of variable length. The 1st string arrives at my server instantly but the 2nd and the 3rd ones arrive really late, like 4-5 seconds delay. The pastebin is here: http://pastebin.com/NGu8MT6D . Sorry for this issues. 

 

Best regards,

#43384 Experimental Drivers for Wiznet-based Ethernet Shields

Posted by VladVictor on 14 January 2013 - 12:55 PM in Beta Firmware and Drivers

Can someone help me with an issue: i have a server somewhere which outputs data that comes through a port. So on the netduino i have a socket that connects send data and then disconnects. The delay between when i close the socket and reconnect again is very big like 3-4 seconds and i receive the data. I tested my server with a web browser and everything works ok, i can see the GET very fast. Here is a pastebin with my code :

#43147 Wiznet driver problem

Posted by VladVictor on 11 January 2013 - 11:49 AM in Netduino 2 (and Netduino 1)

Hello, 

 

I am using the wiznet driver with a netduino board to send some data to another ethernet board ( AVR-NET-IO with Arduino bootloader). I have the code to send data to the socket on a specific port. The behaviour is like this : 1st packet of data arrives instantly but the next one takes like 2 seconds or more. In the code there is not delay or something related to that. Here is the pastebin http://pastebin.com/hbnjkcvd with the code from the netduino. I have tried this code with a socket server c++ on my Mac and it is the same behaviour so not the other board is the problem. Does someone have any idea why this happens ?

 

 

Best regards, 
Vlad

 




#23335 SM5100B GPRS

Posted by VladVictor on 26 January 2012 - 07:44 AM in Netduino Plus 2 (and Netduino Plus 1)

Hello,
I have some problems with this GPRS module to connect it to the network and get an webpage. I succeed in opening a socket but when i want to receive the data it just close it after some time, it just stalls. I am using arduino as a serial communicator for the OSX, everything that goes in the arduino it passes to the SM5100B shield. These are my commands that i pass to the shield
AT+CGATT=1
AT+CGDCONT=1,"IP","wnw"
AT+CGPCO=0,"wnw","wnw", 1
AT+CGACT=1,1
AT+SDATACONF=1,"TCP","www.google.com",80
AT+SDATASTART=1,1 
AT+SDATASTATUS=1
AT+SSTRSEND=1,"GET /search?q=arduino HTTP/1.0"
AT+SDATAREAD=1
I get all ok`s for all the commands but i do not get +STCPD:1  which tells me that i have data to read. Instead i get +STCPC:1 that tells me the connection has been closed by the remote host. I have put it to access my local webserver but it does not log anything, how does it close the connection. Any ideas ?
