Arduino Core 2.4.2 Released

[Courty40]

I saw Core 2.4.2 Released today on Arduino, any thoughts on if it will fix some of the issues we've been seeing ?

[Jason2866]

I tried it (my first build from Tasmota on Arduino IDE, i know why using VSC!!!) Seems good at first look, boots up ;-)

[akpuggy]

Can you please share how you were able to test since latest espressif8266 package is still 1.7.3? I only have 1.73 and 1.50 platforms installed in Atom, so not sure what to use in the platform.io file (platform = espressif8266@?).

[Jason2866]

On Platformio still not available... That was the reason i setup Arduino for Tasmota. And i know why i hate Arduino and changend! Could be espressif8266@2.2.1

[andrethomas]

Works for me too - Can't help but wonder what the extra ~18k of flash will give us!

[andrethomas]

@Jason2866

You do know you can use a 4M linker script, right?

[Jason2866]

@andrethomas Yes i know, was build quick and dirty on Arduino (did i say i hate it?). I have the 4M definition in platformio.ini....

[andrethomas]

@Jason2866 Gotcha... was just checking :)

[Jason2866]

HueEmulation doesnt work :-(

[andrethomas]

I also find build time to be excessive compared to 2.4.1

[Frogmore42]

Looks like PlatformIO just released an update that includes this core: https://github.com/platformio/platform-espressif8266/releases/tag/v1.8.0

[akpuggy]

Sweet! Can now try it out next week... haulted all sonoff projects waiting for this.

[Frogmore42]

Yeah, me too.

[tobox]

Just tested 2.4.2/1.8.0 with a spare sonoff basic: did not come up after firmware update. Maybe it needs to be power cycled, but since I am not at home I cannot do this right now. So maybe some patches for Tasmota are required. Don't use 2.4.2 for critical devices yet.

No problem with 2.4.1.

[Jason2866]

Compiles correct under Atom / Platformio and VSC / Platformio. WemosMini boots up and behaviour seems normal. Still needs HueEmulation Patch :-( (https://github.com/arendst/Sonoff-Tasmota/issues/1639#issuecomment-360218536)

[Jason2866]

Works on Sonoff Basic

[arendst]

Stage is not 2.4.2 but the next beta version. I cannot get platformio to compile 1.8.0 as it complains about SCON python problems. Probably platformio problem but I won't reinstall platformio just now. I'll wait for someone to succeed ;-)

I get this error https://community.platformio.org/t/esp8266-broken-scripts/4767

Just did the pio update and now it compiles just fine but keeps telling me it's stage version....

[andrethomas]

For me it compiles under Linux CLI but I just flashed it to a device and it reboots turning the relays on momentarily and then reboots again... damn... no i have to open something LOL

[Jason2866]

@arendst I have in platformio.ini platform = espressif8266@1.8.0 I think the havent changend the name in release 1.8.0 (cfd48f3 is the same as in arduino release 2.4.2!) P.S. PIO update did say 1.8.0.

[andrethomas]

My linux cli version still has this

;platform = espressif8266@1.7.3
; *** Esp8266 core for Arduino version latest beta
;platform = https://github.com/platformio/platform-espressif8266.git#feature/stage
; *** Esp8266 core for Arduino current version
platform = espressif8266

[andrethomas]

Hmm

[andrethomas]

[Jason2866]

@andrethomas Looks good 👍

[Courty40]

I’ve had a couple of devices (the older ones) that have needed the flash/eeprom cleared and to start again before the are stable. May be related to some of the issues here ?

[Jason2866]

@Courty40 Everyone (here in this thread) should the devices now get running with 1.8.0 aka 2.4.2 :-) Using Platformio (Atom) with entry in platformio.ini platform = espressif8266@1.8.0 and a pio update

[andrethomas]

@Jason2866 I'm tentative on jumping to conclusions on devices that are hard to get to :)

[Jason2866]

@andrethomas I did not say always the easy way :-) -> Dont fix aint broken

[andrethomas]

@Jason2866 Now you're just reminding me of a new way of comparative statement methods I learnt here which never occurred to me before

I always did if (variable == known) Here I learn if (known == variable)

LOL

[arendst]

Well at least platformio now has the correct core 2.4.2 version when 1.8.0 is selected. See https://community.platformio.org/t/espressif-32-8266-new-boards-esp-prog-bug-fixes-for-esp-idf-and-arduino-frameworks/4766

Now someone has to find out if all problems with previous versions have been solved...

I know the Hue fix is not in the 2.4.2 webserver code so that still needs to be patched locally.

[Jason2866]

@arendst Confirmed Text is now correct. I have some devices on testing for a while and none failed (even the sensitive MHZ 19 on Sonoff Basic)

[arendst]

Do you experience quick webpage updates like with previous versions? I tried two wemos with 2.4.2 and they respond very slow; the answer is shown on serial interface at least three seconds before the webpage console is updated...

[wasi54]

Webpage update takes less than 0.1 sec. with 6.1.1.6 - Core/SDK Version 2_4_2/2.2.1 for Power on/off via mqtt. And Wifi is stable and fast since 6.1.1c with STAGE! I am using on Basic,Dual V2 and TH: -DPIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH

And this works again over VPN !

[Jason2866]

@arendst I have the feeling that sometimes with 2.4.2 the webconsole reacts some milliseconds later than with 2.3.0 But it isnt laggy in any way! If i do the same thing again the response is faster as it is with 2.3.0. For me is 2.4.2 is working fine so far. I will measure if sleep is working. If yes i will update some more devices (which are easily reachable)...

[arendst]

Just did a recompile and now it's working fine....

[andrethomas]

Wish I could recompile myself... perhaps I will also work fine :)

Maybe I can avoid having a core dump at 1AM each day :)

[Jason2866]

@andrethomas human code has self correction build in. No recompile neccersary;-)

[andrethomas]

@Jason2866 Not having to reboot for a few days and still work properly would be nice though :-)

[Jason2866]

@andrethomas Total off topic anyway. At my last reboot i lost some memory😎

[andrethomas]

@Jason2866 Yeah, make us a channel on Discord so we can goof off there.

I've uploaded the new code to the sonoff dual that controls my overhead lights in my lab... easy to get to in case it fails.

[Jason2866]

@andrethomas Just fired up Discord (first time): https://discord.gg/Ks2Kzd4

[andrethomas]

No memory leak so far...

[ascillato]

Hi,

Up to now, in my devices there was no freeze nor exception with v2.4.2 with lwIP 1.4 (at 80Mhz) since I flash them. It also seems that the webserver works faster. :smile:

The only downside of v2.4.2 is that sleep will freeze the device. :disappointed:

So, if you are going to use SLEEP, you need to use v2.3.0. If not, use v2.4.2 lwIP 1.4

In my tests, v2.4.2 with lwIP 2 led to reboots with exceptions.

[ascillato]

I like the Discord chat you have opened. What about making that the official chat for Tasmota? We can add that to the readme / wiki.

[Jason2866]

Hi @ascillato why not?! Let Us try. Maybe we can move the non issue stuff out of here. A another benefit users can get a direct response there.

[ascillato2]

Hi,

Closing this issue as esplib v2.4.2 is working fine except from sleep feature.

Please, ask to reopen if needed. Thanks all for the tests and comments. :+1:
