Error : Timeout or Not Found Success String

Question

I’m trying to use the module and can’t get it to work at all. I imported the libraries and made the following arduino sketch based off of the samples that should just connect to my laptop and tcp a simple message (I’ve tried to do this with another computer and my laptop side is fine). [code] #include #include “WizFi250_tcp_client.h” IPAddress servAddr(192, 168, 0, 192); WizFi250_TCP_Client * cli; WizFi250 wizfi250; void setup() { Serial.begin(9600); wizfi250.begin(); wizfi250.setDebugPrint(4); Serial.println(“wifi began”); wizfi250.hw_reset(); Serial.println(“wifi reset”); wizfi250.sync(); Serial.println(“Synced”); wizfi250.setDhcp(); Serial.println(“dhcp set”); //wizfi250.sendATCommand(“AT=WLEAVE ”, 1, 1); Serial.println(“Trying to join”); for(int i=0; i<10; i++) { if( wizfi250.join(“MIAN-WIFI”, “super secret”, “WPA2”) == RET_OK ) { break; } } Serial.println(“Wifi joined”); cli = new WizFi250_TCP_Client(servAddr, 1122); Serial.println(“connecting…”); cli->connect(); while (!cli->getIsConnected()) delay(10); Serial.println(“seding…”); cli->send(“Hello world!”); Serial.println(“sent…”); } void loop() { }[/code] When I launch it and look at the serial, I get the following output: wifi began wifi reset ===== SPI Send ===== AT ================== DBG>>>>Error : Timeout or Not Found Success String Synced AT+WNET=1 No connection happens and no message is transmitted.

Hi I think this problem occur because WizFi250 is not SPI mode. Please refer to this document. [url]http://kaizen8501.blogspot.kr/2014/08/tutorial-for-using-wizfi250-evb-with.html[/url] Thanks

Hi, From what I’ve understood from the tutorial, I need to reset the board (by pressing the function button three times) and then connect it to the arduino and the board will switch into SPI mode. Is that correct? I’ve tried doing that and got the same result. Also I’m using the WizFI250 shield (not the WizFI250-EVB) so I don’t have the exactly same button layout as in the tutorial, and I can’t connect the board directly to my computer and read what it’s saying.

Hi Did you use it? 700×525 107 KB If yes? This is not product of WIZnet. It is made by SeeedStudio. So If you want to use it, you must use library of seeedstudio. please refer to this url. [url]http://www.seeedstudio.com/wiki/File:Wizfi250.zip[/url]

That indeed explains a lot. Thanks! Could you help me with the following problem: When I used the library and client sample provided here: seeedstudio.com/wiki/File:Wizfi250.zip I got the shield to connect to my wifi (I saw it from another device when I did a network scan). However, my computer did not get a tcp connection from the board. Here is what the serial monitor showed(followed by a bunch more of [ERROR: INVALID INPUT}): Join MIAN-WIFI CMD: AT+MRESET AT+MRESET CMD: AT+WLEAVE AT+WLEAVE CMD: AT AT CMD: AT+WSET=0,MIAN-WIFI AT+WSET=0,MIAN-WIFI CMD: AT+WSEC=0,WPA2,password AT+WSEC=0,WPA2,password CMD: AT+WNET=1 AT+WNET=1 CMD: AT+WJOIN AT+WJOIN Successfully join MIAN-WIFI CMD: AT+WSTAT AT+WSTAT AT+WSTAT IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [OK] AT+WSTAT IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [OK] IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) [ERROR: INVALID INPUT] STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [ERROR: INVALID INPUT] [OK] [ERROR: INVALID INPUT] AT+WSTAT IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [OK] IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) [ERROR: INVALID INPUT] STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [ERROR: INVALID INPUT] [OK] [ERROR: INVALID INPUT] IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) [ERROR: INVALID INPUT] [ERROR: INVALID INPUT] [ERROR: INVALID INPUT] STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [ERROR: INVALID INPUT] [ERROR: INVALID INPUT] [ERROR: INVALID INPUT] [OK] [ERROR: INVALID INPUT] [ERROR: INVALID INPUT] [ERROR: INVALID INPUT] AT+WSTAT IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) STA/MIAN-WIFI/192.168.0.184/192.168.0.1/00:08:DC:1C:D5:73/31/55 [OK] IF/SSID/IP-Addr/Gateway/MAC/TxPower(dBm)/RSSI(-dBm) [ERROR…

Hi Unfortuanally, I don’t had been use library of Seeedstudio. So I can’t tell you right answer about your question. I think you have better change UART pins of Fi250 using jumper pin in contrast with Arduino uart pin.
