Uhttpd logfiles help OpenWrt small REST-API

Installing and Using OpenWrt
1

Hi.
I have a arduino-esp8266 that pretend to send data to openwrt router.
Openwrt is a small REST-API server with a shell script that simply write a file.

So, calling to OPENWRT is something like:
http://OPENWRT/cgi-bin/AS.cgi?status=OK

AS.cgi contain that code:

echo "$REQUEST_METHOD $CONTENT_LENGTH" >> $LOGDATA
echo "$QUERY_STRING" >> $LOGDATA
echo "$POST_STRING" >> $LOGDATA

and LOGDATA is something:

GET
status=OK

Arduino code is:

connect_result=client.connect(APIserver, 80);
 if (connect_result) { 
    client.print("GET ");
    client.print(endpoint + "?");
    client.print(data);
    client.println(" HTTP/1.0");    
    client.println("");
    client.stop();
    } else {
    Serial.println("API connection failed:" + connect_result );
  }

Now, the tests:

  • From PC(web browser) -> OPENWRT OK
    (See log up)

  • From Android(Wifi connected-web browser) -> OPENWRT OK

  • From ESP8266-Arduino -> PC(Apache server) OK

Apache log:
192.168.1.82 - - [05/Mar/2020:18:43:39 +0100] "GET /cgi-bin/AS.cgi?status=COMIENZO HTTP/1.0" 404 1053 "-" "-"
  • From ESP8266-Arduino -> OPENWRT NOK
    Nothing happens, No logs, no info.

How I can diagnose the problem? Where are the uhttpd logs?
Thanks.
Al

Not sure what language your client is written in but are you sure that your println() function uses \r\n instead of \n as end of line characters?

Still the same problem..

Jow: yes, println() uses CRLF (\r\n).

It is possible that uHTTPd had some log function or debug????
