IOTA OSI layer 4 protocol?

Question

IOTA claims, on their website, to be OSI layer 4 (transport layer). I would like to get information about this. I'm currently working with a MCU and would like to use this protocol. Is there a protocol?

I'm asking because the IRI is using UDP or TCP, but no IOTA protocol. A library would be also great. Thanks.

Answer 1

I don't think there is a special IOTA protocol. It just leverages the TCP/UDP protocols for data communication. You may refer to this question which is helpful fo me to understand IOTA.
