Sending and Receiving tcp/ip packets from ESP8266 "directly"
Posted: Sat Jun 05, 2021 6:39 amI built a CPU/Minicomputer system from scratch using 74 series logic
and I am writing an operating system for it.
I have an ESP8266 connected to it, using the telnet to serial interface available in the examples.
However this interface only sends/receives ascii directly to/from my CPU. So it basically creates
a remote terminal interface to the CPU.
What I need instead is to be able for the CPU to directly instruct the ESP8266 to send/receive
packets to/from IP addresses. I need to be able to write an interface so that I can call a function
inside my CPU that for example opens a TCP/IP connection with another host
and starts communicating. I don't want to simply receive/send ASCII without knowing
where it came from etc.
What do I need to do? AT+ commands don't seem to be what I want.
I want to have my CPU control most aspects of the connections.
What I am looking for I guess is a kind of native internet interface, without the ESP8266
handling everything.
Do you know what I mean?
I don't know how to explain this properly. I want my CPU to know about what connections are
active, and send/receive to a connection it wants.
Is this done with AT commands? So the CPU would tell the ESP to start a Telnet server
and then the CPU would receive AT responses, and then I would have to parse these AT responses
from inside the CPU to know where it comes from, etc?
Any help appreciated...
Thank you
