If you like Blynk - give it a star, or fork it and contribute!

---

Blynk is a unique IoT platform for connecting any hardware to the cloud, designing apps to control them, and managing your deployed products at scale.

• With Blynk Library you can connect over 400 hardware models (including ESP8266, ESP32, NodeMCU, all Arduinos, Raspberry Pi, Particle, Texas Instruments, etc.) to the Blynk Cloud.

• With Blynk apps for iOS and Android apps you can easily drag-n-drop graphic interfaces for any DIY or commercial project. It's a pure WYSIWG experience: no coding on iOS or Android required.

• Hardware can connect to Blynk Cloud over the Internet using hardware connectivity available on your board (like ESP32), or with the use of various shields (Ethernet, WiFi, GSM, LTE, etc). Blynk Cloud is available for every user of Blynk for free.

"ESP8266_DirectConnect.ino" not working

Hi,

first of all I want to say thank you for Blynk. You are doing an excellent job with it!

I would like to get the "ESP8266_DirectConnect.ino" example running. If I understand it correctly, it would allow directly connect the iPhone app with the ESP8266.

Compiling and uploading the firmware works fine, and I can connect to the "Blynk-AP" with my iPhone. However, when I manually point the Blynk app (version 1.4) to the custom server 192.168.4.1 port 8442, the serial debug output reports the following error:

[1194] Blynk v0.3.1
[1194] Configuring WiFi access point: Blynk-AP
AP IP address: 192.168.4.1
[1194] Listening on port: 8442
Client connected from 192.168.4.2:51312
Error happened or disconnected.Client disconnected.

Should the code still work, or does it need to be updated, to work with the current iPhone app?

Kind regards,
Markus

Issues with arduino wi-fi shields

http://community.blynk.cc/t/arduino-wifi-shield-cant-connect-to-any-server/1949/36

blynk library and Energia boards from MSP430 family - compilation error on template

please rename variable "N" to "NN" inside utility/BlynkUtility.h (from line 26),
because name "N" causer compilation error on ENERGIA/MSP430 launchpads

exactly from:

template <unsigned N, typename T>
void BlynkAverageSample (T& avg, const T& input) {
    avg -= avg/N;
    const T add = input/N;
    // Fix for shorter delays
    avg += (add > 0) ? add : -1;
}

to

template <unsigned NN, typename T>
void BlynkAverageSample (T& avg, const T& input) {
    avg -= avg/NN;
    const T add = input/NN;
    // Fix for shorter delays
    avg += (add > 0) ? add : -1;
}

with this little change, launchpads like msp430f5529 works OK with UIPEthernet example

Integrate into Arduino IDE Library Manager

I do not find Library in Arduino ide 1.6.5 in the library manager.
How can I find blynk-library?

gauge won't read float

sensors.requestTemperatures(); // Send the command to get temperatures
float temp = sensors.getTempCByIndex(0);
Serial.println(temp);
Blynk.virtualWrite(5, temp);

above shows nothing.

sensors.requestTemperatures(); // Send the command to get temperatures
int temp = sensors.getTempCByIndex(0);
Serial.println(temp);
Blynk.virtualWrite(5, temp);

above shows only 28 (instead of 28.31)

Add onConnect/onDisconnect handlers

Received the Following Error in ESP8266_HardSer

ESP8266_Shield_HardSer.ino:31:29: fatal error: ESP8266_HardSer.h: No such file or directory
compilation terminated.
Error compiling.

I initially doughted there might be issues with installing the library but even after reinstalling i had the same issue.

NOTE: All others examples are working fine expect ESP8266_HardSer and ESP8266_SoftSer Examples

Library sends "hardware" commands before OK for login was retrieved from server

Here is a server log :

14:38:55.263 TRACE - Incoming LoginMessage{id=1, command=LoginMessage, length=32, body='5c593f6901354a0783a0d278dcc7be2a'}

completeLogin - is a moment when server sends back OK to hardware for Login command. But as you can see hardware sent 2 commands before login finished.

virtualWrite of double/float not working, sending %f

So I am using an esp8266 and trying to do a virtualWrite of a double/float, and all I get on blynk app is %.3f. I did some more investigating, and found that this is actually a problem with the printf not supporting %f. I am not sure this is just a esp8266 thing, or maybe even an arduino issue. I found this function http://pastebin.com/FdBFk3F4 that should just work instead of snprintf(). You can also see this issue reported at:

http://community.blynk.cc/t/how-to-send-float-number-to-android-app/761/4

esp8266/Arduino#341

Info command

I made investigation regarding https://github.com/blynkkk/blynk-server/issues/56. Approach for requesting info as separate hardware command doesn't fit current server workflow well. So it would be nice if you could add this info to Login command.

Add latest Blynk library to codebender

can't set virtual pins on startup

I can t seem to set any pins in the setup function on an esp8266.
i am trying Blynk.virtualWrite(0, 1); after Blynk.begin(auth, ssid.c_str(), pass.c_str());
but it doesn t work. not even with a 2 second delay beforehand.

the ready serial print comes later than that, after a few connecting attempts

done setup

is threre any flag to know when connection is actually ready and we can start writing stuff?

Using ESP8266 as an Arduino Shield

Hello,
I've had success using Blynk with my ESP8266 in standalone mode, now I'd like to use it as an Arduino shield. I am trying to flash the correct AT firmware so I can use the ITEADLIB_Arduino_WeeESP8266 library. I saw in the examples that Blynk uses this library, and it requires version 0.22 AT firmware. I downloaded this firmware from the Espressif website, but the instructions on which .bin files to flash were not clear to me. I ended up using the NodeMCU flasher program to flash three .bin files at different offsets:
boot_v1.2.bin at 0x00000
user1.512.new.bin at 0x01000
blank.bin at 0x7E000
When I communicated with the ESP using ESPlorer, I typed AT+GMR and got some numbers back, but when I tried it with the ITEADLIB_Arduino_WeeESP8266 library and an Arduino Mega, I was not able to start UART communication. I posted an issue on the ITEADLIB_Arduino_WeeESP8266 github page a few days ago but haven't gotten a response. Since I am using hardware serial with version 0.22 firmware, I did not modify the .h file in the ESP8266 library. Any ideas?

from what I see here, you can use Analog pins as PWM

SimpleTimer library doesn't work with Espressif (solution included)

I know, I know, everyone hates to maintain forks for platforms. It looks like SimpleTimer library messes with esp12e hardware timers in a bad way - I get callbacks as fast as it can vs every second. I, however, found that Timer http://platformio.org/#!/lib/show/75/Timer lib works quite well (I'm sure it will work with regular UNOs of the world, too).

Please update http://docs.blynk.cc/#troubleshooting-flood-error section and enhance the instructions. Or, maybe, switch the library code and examples to use this library instead?

This one works:

#include <Timer.h>

// the timer object
Timer timer;

// a function to be executed periodically
void repeatMe() {
    Serial.print("Uptime (s): ");
    Serial.println(millis() / 1000);
}

void setup() {
    Serial.begin(9600);
    timer.every(1000, repeatMe);
}

void loop() {
    timer.update();
}

Build failing, with "BLYNK_HW_IN is not declared" error

When trying building blynk-library on raspberry pi B rev1, I got error message like BlynkApiWiringPi.h : BLYNK_HW_IN is not declared in this scope and fail to build.

BLYNK_HW_IN is missing in this commit.

And, I worked around this issue by adding preprocessor symbol BLYNK_NO_INFO to linux/Makefile :

CFLAGS =   = -I ../ -I ./ -DLINUX -DBLYNK_NO_INFO

Then, Building is succeeded, and blynk command worked well.
But I think this workaround has some side-effects...

Please check this. Thank you.

How to start blink on raspberrypi b+ on boot

how I can start blink on boot automatically using this command:

sudo ./blynk --token=YourAuthToken

on device/mcu/phone reboot restore state

this could be a function that a user could add in his code on the MCU to restore the previous state before reboot

the ios app should also restore the visual state if it s closed and restarted. currently it starts with a default state of everything off (buttons for instance)

including <BlynkWidgets.h> fails for linux example

Attempting to include BlynkWidgets.h into the example main.cpp fails to compile - can't find Print.h header file.

Is this not the correct way to access the widgets in the Raspberry Pi main.cpp?
