Dear all,

I try to connectSPWF04S toa WPA2 network of my company and I have problem with static IP. The IT guys make a reservation for the module with a specific ip address based onSPWF04S MAC address. When I try to connect the server give to the module a different IP address every time because the MAC address that the module send to the server is very strange as you can see in the picture (the last column is the mac address):0690X00000608rlQAA.png

How I can fix this issue?

Usualy, the AT commands that I send is:

at+s.wifi=0
at+s.ssidtxt=networkname
at+s.scfg=wifi_wpa_psk_text,networkpassword
at+s.scfg=wifi_priv_mode,2
at+s.scfg=wifi_mode,1
at&w
at+s.wifi=1�?�?�?�?�?�?�?

Thanks

Marco

    STMicroelectronics MAC addresses starts with 00:80:E1

    What's the output of 'at+s.sts=wifi_own_macaddr' command?

    I assume MAC is correct.

    Try to use Wireshark, and capture the DHCP handshake. Better if in Open Mode (no WPA, so frames are not encrypted)
