Posted on February 22, 2018 at 22:40Hi,
I'm working with SPWF04SA using UART in a custom project. I have a issue making calls to NTP server. I've tried with several servers, but the behaviour is the same, I can't get response.
This is what I send and what I receive:
+WIND:1:Poweron:170216-fd39c59-SPWF04S
+WIND:13:Copyright (c) 2012-2017 STMicroelectronics, Inc. All rights Reserved:SPWF04SA
+WIND:0:Console active
+WIND:3:Watchdog Running:20
+WIND:32:WiFi Hardware Started
+WIND:21:WiFi Scanning
+WIND:35:WiFi Scan Complete:00
+WIND:19:WiFi Join:BB:AA:EE:AA:50:40
+WIND:25:WiFi Association successful:MyNetwork
+WIND:51:WPA Handshake Complete
+WIND:24:WiFi Up:0:192.168.50.207
AT+S.SOCKON=ntp.inrim.it,123,NULL,u
AT-S.On:193.204.114.105:0
AT-S.OK
AT+S.SOCKW=0,48
AT-S.ERROR:60:IP not ready to send
+WIND:24:WiFi Up::fe80:0:0:0:280:e1ff:febd:f6c5
+WIND:84:NTP Server delivery:2018.2.22:4:21.1.53
And, It is interesting this line:
AT-S.ERROR:60:IP not ready to send
This apears 40 seconds after calling NTP server.
And, this another line is also interesdtin too:
+WIND:84:NTP Server delivery:2018.2.22:4:21.1.53
Well, as I can see, efectivily, the wifi module can get a NTP update, but, where is the response packet that I requested with the UDP socket connection to port 123?
I was expecting something like:
+WIND:55: ...
What am I doing wrong?
Regards
AR
