compilation failure on ESP32

[breezer15]

Hello,

I want to compile a bare minimum Sketch in PlatformIO for a ESP32dev kit.

I get this error message if I try to compile:

.pio/libdeps/esp32dev/Homie/src/Homie/Boot/BootNormal.cpp: In member function 'virtual void HomieInternals::BootNormal::setup()': .pio/libdeps/esp32dev/Homie/src/Homie/Boot/BootNormal.cpp:63:139: error: 'SYSTEM_EVENT_STA_GOT_IP' is not a member of 'arduino_event_id_t' _wifiGotIpHandler = WiFi.onEvent(std::bind(&BootNormal::_onWifiGotIp, this, std::placeholders::_1, std::placeholders::_2), WiFiEvent_t::SYSTEM_EVENT_STA_GOT_IP); ^~~~~~~ .pio/libdeps/esp32dev/Homie/src/Homie/Boot/BootNormal.cpp:64:153: error: 'SYSTEM_EVENT_STA_DISCONNECTED' is not a member of 'arduino_event_id_t' _wifiDisconnectedHandler = WiFi.onEvent(std::bind(&BootNormal::_onWifiDisconnected, this, std::placeholders::_1, std::placeholders::_2), WiFiEvent_t::SYSTEM_EVENT_STA_DISCONNECTED); ^~~~~~~~~ Compiling .pio\build\esp32dev\lib620\Homie\Homie\Utils\DeviceId.cpp.o .pio/libdeps/esp32dev/Homie/src/Homie/Boot/BootNormal.cpp: In member function 'void HomieInternals::BootNormal::_onWifiDisconnected(arduino_event_id_t, arduino_event_info_t)': .pio/libdeps/esp32dev/Homie/src/Homie/Boot/BootNormal.cpp:377:81: error: 'union arduino_event_info_t' has no member named 'disconnected'; did you mean 'eth_connected'?

My platform.ini contains this:

`; PlatformIO Project Configuration File ; ; Build options: build flags, source filter ; Upload options: custom upload port, speed and extra flags ; Library options: dependencies, extra library storages ; Advanced options: extra scripting ; ; Please visit documentation for the other options and examples ; https://docs.platformio.org/page/projectconf.html

[env:esp32dev] platform = espressif32 board = esp32dev framework = arduino lib_deps = https://github.com/homieiot/homie-esp8266.git#develop OneWire DallasTemperature Neotimer

build_flags = -D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY build_type = debug monitor_speed = 115200 upload_speed = 460800 `

My Main.cpp contains this:

`#include

void setup() { Serial.begin(115200); Serial << endl << endl;

Homie_setFirmware("bare-minimum", "1.0.0"); // The underscore is not a typo! See Magic bytes Homie.setup(); }

void loop() { Homie.loop(); }`

I see that the ESP32 build also fails on CircleCI, so probably something has changed in the libraries/framework and homie needs to be adapted.

I could solve the problem now for the time being by reverting to an older version of the ESP32 support package with this line of code in the platformio.ini file:

platform = espressif32 @ 3
