Hello.
I use WIFI D1 R2 (Robotdyn).
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "xxxxxxxxxxxxxxxxxxxxxxx";
char ssid[] = "xxxxxxxxxx";
char pass[] = "xxxxxxxxx";
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
}
void loop()
{
Blynk.run();
}
For a long time I could not understand why the connection to the router and the server all the time falls off - when the board is turned on, it connects and works for 5 seconds, then falls off and cannot connect until it is turned off and on again.
The problem was solved only after I set the processor frequency instead of 80 MHz 160 MHz.
I read in the description to ESP8266 that the frequency of 160 MHz is a turbo mode and stable operation at this frequency is not guaranteed.
Question: What is the reason that the connection does not work at 80 MHz? And will the board work stably at 160 MHz?
Maybe the question is not the address, sorry if so…
Thank you very much!
