Blynk + Particle - how they communicate?

Hi all,

Does any of you know how the Particle libraries communicate with the Blynk servers?
Does the information travel on top of TCP messages, unencrypted?
Is there any sort of protection?

If you know where I can find this info on the docs, I’m happy to read them.

Thank you,
Gustavo.

Currently, plain TCP is used.
Blynk servers also support SSL/TLS encryption, however it’s not implemented in Particle library right now. It could be implemented using TlsTcpClient or a similar library.

thank you, Volodymyr
