Reflashed 1 of the esp-01, which now seem to be okay. I also noticed reflashing with arduino ide dierbaar doesnt overwrite current flash, (Wi-Fi info stayed intact, connected automaticly with nu router) had to reflash with espressive tool first then with arduino ide.
I've also tried erasing the ESP8266 with Espressive Flash Download Tool before flashing with Arduino IDE since I noticed the flash wasn't erased. Unfortunately I've got the same results (losing I2C connection). Same thing with new, previously blank chips.
However enabling DEBUG in code always works for me. Can't say why though. 80 or 160 MHz doesn't seem to make any difference.
I´ve flashed the esp8266 (with the usb espflasher) and edited line 24 and changed the debug.
So far it seems to work, and not loosing connection.
But now all the changes I make in Clock setting (thru my webbrowser) keeps resetting to 0
If I change for example the Green intensity to 10 and click on Set, number 10 goes back to 0 in the webbrowser.
And that goes for all values in the Configure Clock settings section.
The changes are working on the Clock itself, it's only awkward that I need to change all values on that page before I can make some changes.
The behaviour of the tiny blue led on the esp8266 board is not matching the discription of the manual after the flash.
It blinks very short in the beginning when it connects to the router, and then it stays out...
That did the trick, went back from 1.06 to 1.04 esp firmware, the one that was on it when I bought it from you.
So far it seems to work with the debug on.
Except for the little blue led on the wifi board, it doesn't flicker ones a second when connected to the router.
The blue led works fine, when the debug_off line is present.
Strange was also that after the flash all the settings (password, time server) where still in it, and not back to default!
Back in this thread I've written which versions works and doesn't work (for me). At least for me it is clear that something is introduced in newer versions that causes this problem.
The blinkning of the blue led is changed when debug = on.
