ESP8266 test-socket.fth

[andrewtholt]

I notice that Mitch has pushed an example file (test-socket.fth) to the repo.

As I understand it the test word "probe-ssh" sets up a a bunch of callbacks connects to the ssh port of a given machine, displays the string return by ssh and disconnects.

This works fine.

I have modified it to connect to a custom socket server. The connect callback sends "PING\n" and the server responds with "Pong!\n", and disconnects.

This too works fine.

I have made the changes to set respond to a callback that simply displays the stack and put false on the stack. With just this change it works.

What I am struggling with is sending a subsequent command and getting the response.

If at the prompt I send a second command (e.g. " PING"n" server-pcb tcp-write .) I get 0 o/p then

ok Tried to execute a null token

Any advice Mitch ?

Regards,
Andrew

You could try "debug receiver" before issuing the second command.
