Does mDash run in VSCode / PlatformIO?

ciro_bruno · October 26, 2021, 5:50am

Last year I’ve been doing some experiences with mDash in Arduino IDE 1.8.11 on a ESP32 device.

Now I’m trying to include mDash in a new project developed for ESP32 pico D4 in VSCode / PlatformIO.

I’ve installed mDash library through PIO Home Library Manager and copied the same lines used before to this new project. But it shows many errors during compilation and at the end it’s not flashed.

I found somewhere that it’d be required to add

build_flags = -L.pio/libdeps/YOURENVIRONMENTDIRECTORY/mDash/src/esp32/ -llibmDash -DCORE_DEBUG_LEVEL=5

to platformio.ini file.

Now it compiles and flashes, but keeps reseting the device during setup procedure.

I had to comment out the begin command

mDashBegin(DEVICE_PASSWORD);

in order to have the code back to work.

Is mDash really suitable for VSCode / PlatformIO?

Thank you.
Regards

PlatformIO in the newest core version (Process precompiled and ldflags properties of library.properties · Issue #3994 · platformio/platformio-core · GitHub) is now capable of recognizing Arduino precompiled libraries if the library properly declares it. As it says on their README page,

for Arduino 1.8.10 […] Change library.properties by commenting out the ldflags=-lmDash line

So sadly the library is not all setup to work correctly without either uncommenting the ldflags in .pio\libdeps\<env>\mDash\library.properties or by adding the simpler

build_flags = -lmDash

to the platformio.ini. PlatformIO already puts the correct folder in the library search path now. So,

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_deps =
     cesanta/mDash @ ^1.2.14
build_flags = -lmDash

works just fine for compilation.

I had no such problems. Registered on the website, inputted my correct SSID, password and device token and the device came online

If you have problems with the library, write to the library developers.

Hello Max.

Great. I’ve got a big improvement with your information. Now it looks like it tries to start.

Now it shows some errors. First I thought there could be some conflict with the FTP server:

#include <ESP32FTPServer.h> // henrikste/ESP32FTPServer@^0.0.2 String FTP_user = “usr”; String FTP_psw = “psw”; FtpServer servidorFTP; … void setup() { … servidorFTP.begin(FTP_user, FTP_psw); mDashBegin(DEVICE_PASSWORD); … }

Doing so, I get this:

Rebooting… ets Jun 8 2016 00:22:57

Placing mDashBegin(DEVICE_PASSWORD); as the last instruction in void setup(), I get this:

but the device isn’t reboot.

Commenting out servidorFTP.begin(FTP_user, FTP_psw);, the behavior is the same.

SPI drive has an empty partition as big as the code’s itself:

# Name, Type, SubType, Offset, Size, Flags nvs,data,nvs,0x9000,0x4000, otadata,data,ota,0xD000,0x2000, phy_init,data,phy,0xF000,0x1000, app0,app,ota_0,0x10000,0x120000, app1,app,ota_1,0x130000,0x120000, spiffs,data,spiffs,0x250000,0x1B0000,

and mDash doesn’t connect at all:

Btw, should I fill something else in mDash device’s configuration? Or does it fills automatically when the device connects?

Thank you.
