Hi, i need urgent help. When i use blynk with HC-06 with my Samsung Galaxy A5 2017 it say me “Device wasn’t online yet”, and when i try to upload a program on arduino for turn on/off a led for example, it work but the Serial port say me “Login Timeout” every time, and for a small time the led doeasn’t change it state. A days later i try to use DH11, on the blynk i used the label value and all type of label, i connect all correct but they didn’t showed me no one value… next i try dh11 without blynk and he works… so i think the problem is or blynk either HC-06, please help
No need to post the contents of the Sketch Builder here… I removed that from your post.
But you can clarify the exact hardware you are using and how you have it wired up.
I connect RX of HC-06 to pin 11 of arduino and TX of HC-06 to pin 10 of arduino, next a led on pin 13. on the blynk app i added a button setted on digital pin 13… I upload the program, it work, the led turn on or off if I switch the button, but some times the Serial of Arduino say me “Login Timeout” and the led don’t change state even if i push the button
