Hi, we are working on one of the IOT project using wifi module(SPWF01A), using this i'm trying to connect WIFI Access point. But, I am facing issue the connection process. NOTE: I'm using RS-232 communication for sending commands  to SPWF01A . I am getting response for all the Commands but couldn't connect to access point.

Let me know where i am wrong,

I am using below list of commands to connect to WiFi AP,

at+s.ssidtxt=datapack

at+s.scfg=wifi_wpa_psk_text,1234567

at+s.scfg=wifi_priv_mode,2

at+s.scfg=

wifi_region,4

at+s.scfg=wifi_mode,1

at+s.scfg=ip_use_dhcp,1

at&w

at+cfun=1

    In your screenshot there are no SCAN (after WIND:32). Radio seems in IDLE. Please run AT&V and AT+S.STS after WIND:32, and attach both dump here.

    Is there an UART dump without module's reset? Leave it running (scan/scan complete), and provide the output of 'AT+S.SCAN=a,r' command. I see no activity on all channels (status variable called wifi_chan_activity2), and this is quite strange.
