Esp8266 with wifi off

[stedew]

Hello,
I have a small question and maybe someone else already knows the answer.
For testing i want to use a esp8266 (esp12 /nodemcu board) with a nrf24L01+) as a GW (serial).
I have this working but i want to shut down the WIFI completely what instruction i have to use for this?

    wifi_set_sleep_type(MODEM_SLEEP_T);
	delay(1);
    system_deep_sleep_set_option(MODEM_SLEEP_T);```
 

I don't know exactly and also while testing i was pinging the wrong ip so i got a little confused ;-)
What i basicly want to do is use the esp as a high performance GW/node.
So any suggest are welcome.
regards,
Stefan.

Make sure you include this in your sketch

#include <ESP8266WiFi.h>

Then add the following lines at the beginning of your setup()

  WiFi.disconnect();
  WiFi.mode(WIFI_OFF);
  WiFi.forceSleepBegin();
  delay(1);

It should totally disable ESP WiFi functions and basically you end up with an arduino nano.

Tnx spot on :thumbsup:

Before i measure 88mA and now ~ 30mA. In reality the profit (% saving) will be even higher. The test setup is with all node mcu hardware so there will definitly be a higher gain with a "bare" esp.
As for some may ask: why use a esp (nodeMCU) as a arduino?
-"Solid" Integrated 3v3 regulator
-Good RF design(shielding)
-USB RS232 interface
-High processing power (if needed).

-I could not get the wifi gateway rock solid (compared to the RS232) .
From the moment domoticz disconnect (or the ESP lost connection) there was no communication anymore without an intervention to domoticz.

Stefan.

:thumbsup: sounds good. The processing power and memory would allow for a (basic) controller functionality.
