    Any changelog for 3.3.x?


      Now WICED SDK 3.3.1 is released but the CHANGELOG.txt does not mention the

      changes/improvements for 3.3.x.

      Can you update the change log?

        • 1. Re: Any changelog for 3.3.x?

          • 2. Re: Any changelog for 3.3.x?

            It shows known limitations but it is not a changelog.

            People want to know what new features are included in new release.

            And most importantly, what bugs/issues are fixed in new release.

            So we can determinate if we should move our development to 3.3.1.

                Do you really read the CHANGELOG.txt?

                To make it clear, below shows the diff of CHANGELOG.txt between 3.1.2 and 3.3.1.

                There is only one line for the change between 3.1.2 and 3.3.0.

                It even not mentions any change between 3.3.0 and 3.3.1.

                • 5. Re: Any changelog for 3.3.x?

                  Since there is no detail change log for 3.3.1, I just check the issues

                  we are concerned (see below list).


                  TCP connection with STA interface breaks as soon as a device is connected to softAP



                  wiced_rtos_delay_microseconds(...) upon reset issue



                  strstr function in HTTP server



                  HTTP request is split into Header and Body (what code does the splitting?)


                  The problem is the implement of HTTP server in SDK assumes the request

                  is one packet. Thus it does not works if you have header/body splitted request.

                  I think the http server needs fix to properly handle the request from Safari.


                  How to get actually transferred data size in case wiced_uart_receive_bytes() timeout ?



                  I found all above issues are *not* fixed/merged in latest SDK.

                  All above issues have been reported for months.

                  I'm very frustrated with such situation after waiting for a long time for new release.

                  Can someone help?

                  • 6. Re: Any changelog for 3.3.x?

                    Unfortunately, this is the only changelog.txt we have to work with at this time. If the developers provide more details, we will update the forum. 

                    Perhaps one of the AEs can address your specific concerns.
