Blynk ports and particle hardware

Issues and Errors
1

Hi,
I was wondering if someone knew what was the ports that the blynk client uses in the particle dev kits.
is it 8442 and is based on plain TCP/IP sockets?
meaning no security at all?

thank you!
Gustavo.

Hello. Correct. Blynk server supports also 8441 port that is for hardware that supports SSL/TLS and particle is not this hardware :).

@gusgonnet if security is important for you it is recommended to install Local Blynk Server. So hardware <-> server communication will be within local network with no security problems.

oh, this is sad.

perfect! this sounds like a great option.
Thanks a bunch @Dmitry!
Gustavo.

What is the hardware that supports SSL/TLS? I imagine one is the raspberry pi, the others are which ones?
thanks

@gusgonnet: There are many:

  • Any Linux/Windows-based single board computer
  • BlynkBoard, ESP2866, NodeMCU, etc.
  • Espruino
  • WiPy
  • Arduino Yun (should be supported soon)
  • Arduino MKR1000 (should be supported soon)
  • Arduino WiFi101 Shield (should be supported soon)

Also, there are some boards that should support direct SSL in theory (we didn’t try it with Blynk):

  • ESP8266 as a Shield
  • SIM-900, SIM800
  • TI CC3200-LaunchXL
  • TI Tiva C Connected LaunchPad
  • EMW3165 (not yet supported in Blynk)

Hope that answers your question!

this answers my question, thank you.

another one: what work would be required to make Particle Photons or Electrons to be part of this list?

Is there a technical reason? maybe the hardware they use doesn’t support SSL/TLS?
or it could be a matter of time and work? maybe porting the BlynkBoard or the ESP8266 code to particle libs?

thanks a lot
Gustavo.

No, we can’t do that.
It’s current Particle platform limitation - they may decide to implement it at some point of time…

BUT - there are other options to build security. Gateway, local server, etc…
