1. First of all, you should use a PRISM compliant CF wireless LAN card. If you don't use the PRISM compliant card, the STS LED of EZL-80c will blink very fast. And you need uncheck ARP option in the ezSerialConfig for some APs. If EZL-80c is connecting to wireless LAN network, STS LED and P0 will maintain low. 2. Your AT commands are OK. But there's no response... If you want use ATC mode, you should set EZL-80c to ATC mode by ezSerialConfig. And you should set the baudrate as you want. (115200 bps is good because ezSerialConfig is also 115200bps.) > Kevin wrote: > ~~~~~~~~~~~~~~~~~~~~~~~~~~~ > Hello, > > I would like to establish a TCP/IP connection between my EZL-80c and a computer on a local WIFI network. The computer is connected to the WIFI network through a wired LAN and the WIFI Access Point is actually just a Linksys WIFI Router. > The EZL-80c has the latest firmware, and I have successfully used the serialConfig tool to read and write WIFI environment variables (Infrastructure Mode, "linksys" SSID, channel 6 (same as router), and no WEP. However, when I plug in my Socket CF wifi card, and then apply power, nothing happens. This is true for ATC, COD, and T2S modes. I have also tried checking the DHCP box and using the start option to automatically try and connect on boot up. I have checked the STS_LED, LINK_LED, and P0 (all are HIGH) which means there is no TCP activity. Should the EZL-80c automatically obtain the IP address specified with serialConfig when it is booted up with the CF card inserted? Additionally, when I try to use ATC mode, none of my commands (ie. AT+PRIP=192.168.1.101[cr], ATZ[cr], AT+PRP=1470[cr], ATA(D)[cr]) give any response from the EZL-80c. However, I know that the TX pin on the EZL-80c is working because I get the boot up message in hyperterminal when the CF card is not inserted. I have also made sure that both the EZL-80c and my serial port are using the same configurations and speeds (8n1 and many different baud rates). Can you please give me detailed instructions/settings/commands on how to connect my EZL-80c to the computer mentioned above (assuming it is running ezTerm with port 1470 open)? Thank you. > > Kevin |
