I have setup the module as miniAP with following script: (

http://elektronikab2b.pl/technika/32973-spwf04sa-miniaturowy-modul-wi-fi-z-oferty-stmicroelectronics---przyklady-zastosowan

)

AT+S.WIFI=0

AT+S.FCFG

AT+S.SSIDTXT=test_ap

AT+S.SCFG=wifi_priv_mode,1

AT+S.SCFG=wifi_mode,3

AT+S.SCFG=wifi_wep_keys[0],76543210ab

AT+S.SCFG=wifi_wep_key_lens,05

AT+S.SCFG=ip_use_dhcpc,2

AT+S.WIFI=1

AT+S.WCFG

AT+S.RESET

once it restarts, this is what I get:

Port opened

SPWF04SA WIFI test program start.

Setup SPI done.

Reset module...

Start module...

Done.

now my problem is this: once I try to connect with my phones wifi f.e., it does recognize that a station gets associated, but it does not give out an IP, what do I have to setup for it to work?

RX:02 1A 48 13 00 AT+S.WIND:72:Station Disassociated:<wifistate=Ready to TX>:00:16:EA:E5:89:FE:1

PS: I see the 'Configuration Failure' but its non-halting and I dunno what HW pullup resistor is meant here. This all worked fine before I upgraded the firmware (SPWF04S-170726-b7ac1ba)

PPS: if I downgrade back (firmware SPWF04S-170216-fd39c59), it works but all the fixed problems (with SPI communication) are back, so this has to be a firmware issue

I'm also seeing the same problem.

When using Mini-AP mode with the ip_use_dhcpd=1 I'm not seeing the Win29 DHCP Reply messages, only the Wind 28 Station Associated messages.

When connecting to an old XP machine it works every time, but with Win10 its less than 10%, and instead of getting a DHCP allocated IP address it uses its Alternative address instead.

Unable to tell if its Win10 not sending a DHCP request or the SPWF04 not servicing the request correctly.

Maybe Win10 is not being told that a DHCP server is available in the device so it doesn't make a request.

All very frustrating so any insight appreciated.

Hello,

if you are not sure about Win10 DHCP settings, please verify that 'Obtain an IP address automatically' is checked in IPV4 dialog of your wireless network adapter.

Then, if not already done, please reboot the SPWF04 (either AT+S.RESET or HW reset) and then try associating the PC again.

If this does not make the things better, please attach your module's configuration (AT+S.GCFG) and status (AT+S.STS) to this topic.

Thanks for getting back to me so quickly.

Yes the Win10 machines are all looking for DHCP allocated addresses across wifi.

I've loaded Wireshark onto one laptop so I can see if a message is not being handled, unfortunately since that time I've not had a failure on that computer (sometimes can work for hours at a time then fail for equally long times).

Since the firmware is not changing in this time I'm sure it must be a timing and/or network thing.

I'll add in option to dump out the variable and status and post up soonest, and if I get a failure on wireshark will post this as well.

Thanks
