Can't Get example with AutoConnect to Work
DanMan32 opened this issue · 3 comments
I tried the example TelnetServerWithAutoconnect and I can't get it to do what I believe it is supposed to.
I can get connected to the WiFi alright through the initial Autoconnect AP and from there set up AutoConnect to connec to my WiFi,
And after that I can connect to the Telnet server using Putty.
But all it seems to do is echo what I type, If I understand the code correctly, I should get informed from the serial connection when I make the telnet connection, what I type in serial should be output to the telnet connection, and if I enter 'ping' in the telnet, I should get a response 'pong', an get disconnected if I enter 'bye' the telnet session should disconnect.
But nope, only echoed characters.
Speaking of echoed characters, I recommend a function to switch echo on and off. That may satisfy the other request to hide characters typed when entering a password. There may be other circumstances where one might not want an auto-echo, but be able to control what gets echoed, especially if they are processing input a byte at a time to determine what key was pressed and produce an action according to what was pressed.
Example: esc to go back a menu
P.S.
Seems to be a flaw in the loop (main) section of the mentioned sketch where when there's a byte in the serial buffer, to echo it back to the terminal.
serial.read() returns an integer, not a character.
Hey,
echoing characters has something to do with the Telnet client negotiation and not with the ESPTelnet.
Please see #64. You must either change the setting in your Telnet client or negotiate the local echo with the client.

No, telnet.print() is a template function, the type is detected and kept intact.
