Hi Everyone !

I am using  SPWF01S wifi module.

I would like to assign static IP for my module, so that my module will have same IP address even when connected with different networks.

I used the following AT Commands

at+s.scfg 

= ip_use_dhcp,0

at+s.scfg = ip_ipaddr,172.10.10.50

at+s.scfg = ip_netmask,255.255.255.240

at+s.scfg = ip_gw,172.10.10.1

at+s.scfg = ip_dns,172.10.10.1

when I use the above commands the module is allotted with static IP but SOCKET connection is not happening but when I use 'ip_use_dhcp,1' then everything works fine.

Help me to solve this issue.

    Hello!

    I think You try to use wrong tcp/ip settings.

    If you have configured netmask as

    255.255.255.240

    you may

    use ip-adresses in range

    172.10.10.1

    - 16 only. But you try to use 172.10.10.50.

    It's not in range.

    Hi,

    please share your use case. Socket server or client? Which FW version (update to the latest one, if not)?

    Regards

    Hi Jerry and Daniel,

    Jerry : The FW version is 3.5 and I am using my module as socket client.

    Daniel : You are right the IP address should be in the range of 1 to 16. I have used 172.10.10.8 and now it is working fine.

    Thank you guys for the suggestion.
