App connects to the server but devices always offline

[Luigi_Puntaloro]

I have the same problem with my mega arduino. with 0.32.2 everything works, from 0.33 nothing goes … The application connects to the server but always says offline

The application connects to the server but always says offline

A bit conflicting… is the App connecting to your Local Server or not?

If not, then read through this topic and try the suggestions… although the primary issue here was the use of Particle IDE… which I do not think you are using with a Mega

But if it is connecting, then do the projects run fine, but just show the device as disconnected (even if it is not)? If so then update your App (as this was due to another issue in another topic and since resolved… )

If something else… please clarify with details.

hi,
I do a bit of clarity …
the app for android connects to the local server and I see my projects …
the status of the hardware is always disconnected and in fact the controls do not work …
I have updated the project with the latest 0.51 library
thank you

Have you made all the recent required changes to the ports on all of your devices? All the sketches now need to use port 8080

[Luigi_Puntaloro]

I have not modified the schetch … what should be changed? the new library does not have references inside?

[Gunner]

Moved all this to your own topic.

@Luigi_Puntaloro

what should be changed?

As stated…

@Gunner

All the sketches now need to use port 8080

@Luigi_Puntaloro

the new library does not have references inside?

As documented via announcement topic…

New Blynk Library v0.5.1 is Released (important for local server owners)

In this release New hardware support: TI CC3220 (Energia IDE) General improvements Blynk switched to using port 80 by default. Certificates added for easier switching from Blynk Cloud to Let’s Encrypt Add setMin & setMax to widgets Bugfixes: Fix pinMode command Fix ESP32 WiFi credentials provisioning PlatformIO, Particle, ARM mbed and OpenWRT packages have been updated accordingly. Full list of supported hardware is available here NOTE: if you have local server and uploa…

Thank’s

Not Work!!!
I did all this:
sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
#define BLYNK_DEFAULT_PORT 8080
Blynk.config(auth_local_server, local_server, 8080);

I loaded the schetch but arduino never connects to the local server…

Help me…please!!!

[Gunner]

I can’t look over your shoulder… I have no idea what all you are doing with your sketch…

@Luigi_Puntaloro

Blynk.config(

…but Arduino’s tend to need Blynk.begin() not Blynk.config()

[Shadeyman]

This works perfectly for me …

  Blynk.begin(auth, ssid, pass, server, 8080);

@Gunner I did wonder about this:

@Dmitriy

Blynk.config(auth_local_server, local_server, 8080);

What uses Blynk.config() ?

[Gunner]

ESPs running in standalone mode use Blynk.config() as a non-blocking connection management method… but requires something like these commands first, in order to initiate the actual WiFi link… and these commands don’t work with ESP in shield mode, as used with Arduinos.

Blynk.connectWiFi(ssid, pass);

or

WiFi.begin(ssid, pass);

[Luigi_Puntaloro]

I use this to connect the hardware:

#define BLYNK_DEFAULT_PORT 8080
Blynk.begin(auth, server_ip, 8080, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);
