- Wed Oct 25, 2017 1:19 pm #71211 Dear Sirs,
in one of my projects, I want to use ESP8266 more like Arduino, without WiFi and using all of its potential and speed.
So the question is, is there any way to fully "disable" WiFi and all underling support routines and interrupts?

Thanks and Best Regards,
Mike Kranidis

What you do is to let the WiFi-stack go to sleep, but since there's always a watchdog timer checking the stack, you'll have to reset that watchdog every once in a while (though it should be possible to completely turn off the watchdog).

See this article on Hackster.io for more information.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

I will try to implement it.

- Thu Oct 26, 2017 6:43 am #71229 there are other (better) ways to disable RF.
you can do
ESP.deepSleep(1000, WAKE_RF_DISABLED);
in setup() if you discover that RF is enabled.
So RF will securely be disabled after reboot and for the loop().

Or have a look at https://github.com/cnlohr/ (especially channel3) for what can be done with esp8266 hacking.
