Hello guys,
Spent some time to figure out what is is happening…
I have some custom HW, based on ESP-WROOM-02 module (use it in Arduino as generic ESP8266 device). The issue, that WDR is happen at Blynk.begin(…). Moved to NodeMCU 1.0 (just to be sure that it is not HW issue) - the same results.
The issue is seen at Blynk_Release_v0.6.1.
Moved back to Blynk_Release_v0.4.8 (pretty old, I used before) - no issue found and everything works find for both HWs.
Arduino 1.8.9;
ESP8266 Board package 2.3.0 and 2.5.0;
//Source code
BlynkTimer timer;
int timer_1s = 0;
BLYNK_CONNECTED()
{
Serial.println("Connected");
}
void sendSensor()
{
Serial.println(timer_1s++);
Blynk.virtualWrite(V1, timer_1s);
}
void setup()
{
Serial.begin(115200);
Serial.println("");
Serial.println("Begin");
Blynk.begin(auth, ssid, pass);
Serial.println("");
Serial.println("Started");
timer.setInterval(1000L, sendSensor);
}
void loop()
{
Blynk.run();
timer.run();
}
Any help appreciated.
Thanks,
Alexander A.
do you really need to check the sensor every second?
what type of HW do you use?
It is just sample code… the issue is WDR during “Begin”.
could you provide the WDR code you see on serial port?
I will later today… but I saw different ones, like (3,0), (3,2)…
Previous release works fine.
Do you have the latest update for nodeMCU --> 2.5.0?
I’m using NodeMCU too ,
I do not have WDR problem unless I use a bad loop
Hello Alexis,
I use this HW : HiLetgo ESP8266 NodeMCU LUA CP2102 ESP-12E
(https://www.amazon.com/HiLetgo-Internet-Development-Wireless-Micropython/dp/B010N1SPRK/ref=sr_1_1_sspa?crid=31KAL9KRKKSBN&keywords=nodemcu&qid=1557255637&s=gateway&sprefix=nodemcu%2Caps%2C-1&sr=8-1-spons&psc=1 )
What arduino version do you use?
ESP8266 Board package?
Blynk Lib version?
IOS / Android apk versions?
NodeMCU HW?

Alexander A.
Noooo!
I’ve given up on 2.5.0, it’s awful and causes so many issues around the point when the hardware tries to connect to Wi-Fi.
Downgrade to 2.4.2
Pete.
Yes last 2.5 is awful, I am using 2.5 beta 3.
Arduino 1.8.9;
ESP8266 Board package 2.5. beta 3
NodeMCU LoLin V2
Blynk 6.1
Android 6
Hello Alexis,
Thank you.
I will check again.
What is the version of Android apk?
Regards,
Alexander A.
Last blynk beta version 2.27.6

The same results for 2.5.0-Beta3 and 2.4.2 - WDR!

and it works for Blynk_Release_v0.4.8 release (everything is the same, except Blynk libs and tools in Arduino folder)
