Huge Blynk Library update! v0.5.0 [Arduino, PlatformIO, Particle, MBED, OpenWrt]

Announcements
1

PlatformIO, Particle, ARM mbed and OpenWRT packages have been updated accordingly.

In this release

  • General improvements

    • Forget about “flood errors”. Probably :wink:
    • Library is now easier to port/run on 3rd party hardware
    • We now use a single implementation of BlynkFifo
    • Better diagnostic/debug prints
    • NeoPixel lib is no longer included in Blynk release zip package.

  • New hardware support:

    • ESP32
      • Bluetooth LE initial support + example
      • SSL (secure connection) support + example
      • App Export example for ESP32 (with WiFi credentials provisioning)
    • ESP8266
      • SSL stability improvement (still not perfect due to a bug in ESP Core)
      • SSL now checks certificate chain (previously fingerprint was used). Needs 2.4.0-rc2
      • BIG stability improvements in Shield mode (AT commands)
    • Realtek RTL8710 / Ameba support
    • Arduino UNO WiFi support
    • WIZnet WizFi310 support
    • Improved ARM mbed support
    • Improved Linux support
    • All frameworks are now enabled for PlatformIO library

  • Bugfixes:

    • Unexpected “Login timeout” during redirect (#374)
    • 100% CPU load on linux/raspberry
    • Compile Error with Arduino 101 (#369). Please keep in mind that #304 is still there…
    • Call BLYNK_DISCONNECTED() on unsuccessful write (#371)
    • RFDuino uses BLEPeripheral now
    • Travis CI build is fixed

Full list of supported hardware is here.

could you please elaborate this?

@wanek the library now automatically delays sending out commands, if the user sketch tries to do it too fast.

Does it mean we can put Blynk.virtualWrite to void loop? :smiley:

You can try.

wow, this is a great idea, considering that 70% of newbies actually putting virtualwrite to main loop!

I think the practise should still be discouraged because loop() will still be a bad use of resources, even if Blynk was able to cope with it.

Yes that is just to make newbies happy.
BlynkTimer usage recommendations still apply.

Great, more happy newbies “flooding” the forums with bad coding practices becasue new library enhancements will “fix everything” :thinking: Gee, Thanks :stuck_out_tongue_winking_eye: JK

Well, those Makers will encourage @vshymanskyy to create better and stable code for the library, so every disadvantage has it’s advantage :wink:

Hello,

I’d like to be sure…
So I’ve just to remove old Blynk libraries/tools folder and replace them by new libraries and tools folders, at the same location?

13

@Alx-I yes

14

I can certainly see BIG stability improvements with my MEGA/ESP-01 setup… 20 hours and counting without a single need to activate my built-in reconnect routines. and considering how bloated that testbench project is, and my limited coding abilities… this is a loong time :stuck_out_tongue:

:+1::+1:

I don’t suppose there is a “Total Neanderthals How-to Guide” for doing so with NodeJS on the RPi? :wink:

Can please explain me anyone how can i update the library on a raspberry pi 2 with raspbian?

16

@Andy_Wand Check the documents and Help Center… if using WiringPi (C++) follow the links and directions accordingly, if using NodeJS, that is presently stable at v.0.4.7 with no current way to upgrade.

I use node but blynk or so crashed after few days i think its the 100% cpu usage or so that’s why I wanted to update.

18

That issue seemed to be related specifically to the C++ method and beta 0.5.0 (since updated as stable).

Node v.0.4.7 has been around for a long time and is stable… but you might have code issues that, in Linux, need to be ‘caught’ else they stop the script.

Best to start a NEW topic and provide as much detail as possible, and show your full code.

Thank you very much, Blynk Gurus. You guys are awesome!

A question. Does this upgrade cure the instability of ESP when doing Blynk.syncAll() when there are lots of V pins?
