Network Comms not supported with WLAN ESP32

[wardelder]

When I try to connect the Network Comms to the WLAN ESP32 component, the Network Comms component properties shows "Not Yet Supported" in the Status field. Will there be support soon?

[BenR]

Hello,

It should already be supported, that message may be an oversight, I'll investigate for you.

[wardelder]

When I try to compile I get multiple errors. I have attached the program and errors.

[BenR]

Many thanks for letting us know.

I have fixed some of the problems now including the Nework commsa saying ESP32 Wifi is unsupported and some of the generated Errors. Currently talking to Leigh about the other errors and how we can fix them. They are very minor but the ESP compiler by default is very picky about things.

[BenR]

While we get this sorted you can make your compiler less strict by following the instructions below.

File to edit is IDF_Folder\tools\cmake\build.cmake

Section starts with this
list(APPEND compile_options

Here are the settings I'm now using to get around the error and to remove some of the warnings.

Code: Select all

    list(APPEND compile_options     "-ffunction-sections" 
                                    "-fdata-sections"
                                    "-fstrict-volatile-bitfields"
                                    "-nostdlib"
                                    # warning-related flags
                                    "-Wall"
                                    "-Werror=all"
                                    "-Wno-error=pointer-sign"
                                    "-Wno-error=unused-function"
                                    "-Wno-error=unused-but-set-variable"
                                    "-Wno-error=unused-variable"
                                    "-Wno-error=deprecated-declarations"
                                    "-Wextra"
                                    "-Wno-unused-parameter"
                                    "-Wno-unused-function"
                                    "-Wno-unused-variable"
                                    "-Wno-discarded-qualifiers"
                                    "-Wno-pointer-sign"
                                    "-Wno-sign-compare"
                                    # always generate debug symbols (even in release mode, these don't
                                    # go into the final binary so have no impact on size
                                    "-ggdb")

The lines I have added are,

"-Wno-error=pointer-sign" - this is the only one to get it to compile succesfully.
"-Wno-unused-function"
"-Wno-unused-variable"
"-Wno-discarded-qualifiers"
"-Wno-pointer-sign"

Let us know how you get on if you decide to do this and I'll see if we can solve the problem here.

[wardelder]

That worked! I can now create and run a webserver from the ESP32. Thank you!

[LeighM]

The original errors have now been fixed.
The above work-around is no longer required.

Hello Matrix Team,

I´ll tried to compile the above example programm to compile an use as a tutorial for me, but unfortunately I´ll get the following compiler messages.

It looks like the ESP toolchain does not like brackets (parentheses)
try changing the project name from v9_esp32_wifi_test_(1) to v9_esp32_wifi_test_1
