ต่อจากข้างล่างนี้มันมีอีกไหม

4

มีครับเป็นข้อความเดียวกันกับที่วงมายาวลงไปเลยครับ

5

ลองใช้คำสั่งนี้แทนของเดิมดู

Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass, "blynk.cloud", 80);

จริงๆ เหมือนมันจะเชื่อมแล้วนะ

6

ได้แล้วครับขอบคุณมากครับบ

7

อีกวิธีที่จะเช็คได้ว่าเชื่อมยังคือให้มันแสดงข้อความตรงนี้ออกมา

BLYNK_CONNECTED()
{
Serial.println(" CONNECTED");
  // Change Web Link Button message to "Congratulations!"
  Blynk.setProperty(V3, "offImageUrl", "https://static-image.nyc3.cdn.digitaloceanspaces.com/general/fte/congratulations.png");
  Blynk.setProperty(V3, "onImageUrl",  "https://static-image.nyc3.cdn.digitaloceanspaces.com/general/fte/congratulations_pressed.png");
  Blynk.setProperty(V3, "url", "https://docs.blynk.io/en/getting-started/what-do-i-need-to-blynk/how-quickstart-device-was-made");
}

ถ้าเห็น CONNECTED แสดงว่าเชื่อมแล้ว

8

สรุปว่าทำอะไรไปครับ

9

Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass, “blynk.cloud”, 80);
ใช้อันนี้ครับ

ok เยี่ยมครับผม
