Fantastic tutorial. I watched this and followed your code rather than trying to figure out the needlessly complex examples others give. I'm connected to my server now, and very excited to start experimenting. Thank you!

Thanks man, works very fine for me, only got some latency but that might be cause of my wifi

[manjunathg]

[PeterMisovicProfile]

[fortedexe]

Hi, I got the error: No such command "serialports", pls help me with this

[zackzeid]

hey ali ! do u know how to do it with node red? because i will be doing my final year project simillar like this but using node red

[jackbrady]

I noticed an issue with the code. I think the reconnect() function does not return a value once it is connected. This means that it will keep trying to connect even after it has already connected.

Thank you could you share a code to connect with ubidots platform but support static IP

[mcomulu]

Is the callback function always neccassary?

[karthisubramanian]

which platform are you using for writing the code?
can we use arduino ide or energia for writing the code?

[shilpasv]

[chronuszeus]

Hi. I´m try to connect to wifi, but show the error:
src\main.cpp:9:27: error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
WiFi.begin(ssid, password);
Does anyone know this error?

[jojomevo]

why u do not post the code as text please?

[KarlFriedrichLange]

Well done. Please change the scenes more slowly. I can not write so fast.

[duchoang]

[stickylabhome]
