I am using SPWF04 module for embedded web server application. I can access web pages on the web server from the PC/laptop, but when i access from android phone wifi module reports station disassociation.

Can you please detail the scenario when the module reports station disassociation? console log, what is the station doing, ecc.

I suppose your SPWF04 is configured as MiniAP, isn't it?

The SPWF04 configured as MiniAP. When i connect the wifi on the phone, it showing as connecting...... obtaining ip address..... and this process is continuing. On the console showing station is associated and after few seconds showing station is disassociated and this is process is continuing.

From log I understand you are setting WEP encryption without a password.

I'm not sure it is a valid configuration.

Actually, I cannot get an IP until I set a valid password (40/104 bits) in the SPWF04.

Ex.:

pwd=54321

AT+S.SCFG=wifi_wep_keys[0],3534333231

AT+S.SCFG=wifi_wep_key_lens,05

Ex:

pwd=1234567890123

AT+S.SCFG=wifi_wep_keys[0],31323334353637383930313233

AT+S.SCFG=wifi_wep_key_lens,0D

See the attached console log, i implemented password and still same cannot connect with android phone.

But i can connect with laptop without any issue. Actually i was using version FW1.0.0, this version dont have any connection issue with both PC and phone.

Thanks for the log.

Is the phone disassociating during the access to the web server, or is the phone failing to get an IP?

I am not accessing web server because its not even connecting to the wifi properly. I think phone is  failing to get an IP. When i connect  the wifi on the phone it show

 connecting...... obtaining ip address..... and this process is continues.

Can you please capture the DHCP Offer or ACK packet sent by the SPWF04 to the phone and send to me?

Also please try setting a static IP on the phone for the 'Release Tool' network.

How i can

capture the DHCP Offer or ACK packet sent by the SPWF04 to the phone?
