Hi JColvin, We have successfully scanned 12 wifi signals using pmod wifi module and WIFIScan example in sdk 2.16.4 vivado version. Now we want to connect to a wifi router with below information: ----------------------------------- scanned wifi info Start ------------------------------------------------------------- Scan info for index: 10 SSID: my_wifi BSSID / MAC: xxxxx Channel: 11 Signal Strength: 85 Infrastructure Network Beacon Period: 100 dtimPeriod: 1 atimWindow: 0 Security info: WPA2 WPA Preamble Privacy Reserved Reserved Reserved IE 0 1 1 1 0 0 0 0 Count of support bit rates: 8 Supported Rate: 1000 kbps Supported Rate: 2000 kbps Supported Rate: 5500 kbps Supported Rate: 11000 kbps Supported Rate: 18000 kbps Supported Rate: 24000 kbps Supported Rate: 36000 kbps Supported Rate: 54000 kbps -------------------------------------------Scanned info end ---------------------------------------------------------------------- --> We are using TCPEchoClient example to connect with the above mentioned wifi router. But when we are implementing sdk project we are getting error: ------------------------------------------- Error start---------------------------------------------------------------------- WiFiTCPEchoClient 3.0 Connecting to network... Unable to connect, status: 268450048 Closing TcpClient, Done with sketch. -------------------------------------------- Error end --------------------------------------------------------------------- --> We are providing proper szSsid and szPassPhrase but still not able to connect. --> please guide us how to connect. Is this issue is related to type of security in wifi router or something else? Please help us.. we are really in trouble. --> Attaching the c++ file using from PmodWifi example. Regards Pulkit TCPEchoClient.cpp

Hi colvin In our design we did wifi scanning and we successfully scan all the wifi in our surrounding . but when we trying to build a connection with our wifi router using tcp/ip echo either client or server then it give this error . TCP Echo Server Connecting... Unable to make connection, status: 0x10003900 Closing connection 0 sockets listening on port: 44300 So, can you provide some guidance how we resolve this problem connect wifi successfully . Please let me know . Thanks Regards Pulkit

Thanks for your prompt reply Colvin. In our design we don't want to use SD card . So, our setup is like we have a PC connected to an fpga board with ethernet cable. Pmod wifi module is also connected to the same fpga board. We want to send some data (in internet packet format) to fpga through ethernet port. Fpga will collect that data and will route it to pmod wifi module which is already connected to wifi router. So suppose we open Google Chrome on connected PC and try to open digilent website. That query will be forwarded to fpga on the connected ethernet port. Fpga will capture that data and forward it to pmod wifi. Wifi module is connected to wifi router. So it will fire our query on internet to access digilent website. In the same fashion, when digilent website respond to our query we will get data from wifi router -> wifi module -> fpga -> ethernet port -> PC. This our project that we want to implement using pmod wifi module. Is this possible ? Please let us know as soon as possible . Thanks Regards Pulkit

Hi JColvin, Thanks for your reply on my question. I want to know that can i use this digilent PMOD wifi module to get internet access by making it a TCP IP client? My purpose is to access internet using this pmod wifi module and FPGA. Is this module a right choice for the mentioned purpose ? Please guide me. Thank you. Pulkit

Hi, I am trying to interface Pmod wifi module with FPGA since 30 days but it is not responding. Today i tried to simply scan wifi using pmod wifi module. It again failed. Below is the error: Connected to COM3 at 9600 Wifi Scan 3.0 Scan Failed Status value: 268443650 End of Demo I am attaching vivado design and sdk design screen shots. Please help to find out if i am doing anything wrong with the IPs. Does digilent's pmod wifi module really work with the IPs provided ? Thank you.

Hi JColvin. I tried to configure pmod wifi on Arty A7-35T with TCP IP Echo Server IP. I was not working and i could not see anything on serial terminal. Then i commented all the statements in TcpEchoServer -> main.cc and wrote a simple code to print "hello world". It worked and i got it on terminal. Then i again included "#include "PmodWIFI,h" statement and wrote "hello world" code after this statement. This did not work and nothing appears on serial terminal. Can you please guide me on this issue. Thank you.

Thanks JColvin. I increased the memory size as suggested by you and that solved my problem. Now my next task is to configure Pmod wifi module with arty A7-35T with an IP address and my wifi address + password, and ping it from another computer connected with same wifi network. I am using TCPEchoServer example provided in Pmod IP library. As shown in attached screen shot, i have passed my wifi credentials in main.cc file, but i am not able to ping Pmod wifi module even after successfully build the project and program the ARTY A7-35T board. Please provide some guidance. Thank you.

Hi, I am working on a project where i am using Digilent's Arty A7-35T along with Pmod WIFI module. My task is just to interface microblaze with Pmod WIFI module, configure it with an IP and ping it from another PC in the same network using vivado 2016.4. in my block design i am using only microblaze (with 128 KB memory),DDR3 and wifi module. when i am building sdk application, one error generates related to internal memory of microblaze. "Description Resource Path Location Type hello_app.elf section `.text' will not fit in region `microblaze_0_local_memory_ilmb_bram_if_cntlr_Mem_microblaze_0_local_memory_dlmb_bram_if_cntlr_Mem' hello_app C/C++ Problem" Can someone help me to under stand this issue. I am not expert in embedded design so not able to handle this linker script issue. Please help. Thanks

I need to design an entity in which i have to capture ethernet data coming from PC and send it to Pmod wifi module and vise-versa. I am using arty -A7-35T digilent board. I not expert in this and not able to understand how I can use microblaze and configure wifi module for TCP/IP transfer. Please help me out. Thank you

Hi.. I just started a project in which i have to use Pmod wifi and have to access internet. I must use RJ45 provided on arty A7. Can someone help me to start with as i am totally new in this field. Thanks in advance.
