AT-Commands ESP8266 01: AT+CIPSTART: How to fix response Link type Error / Can't connect with TCP

I am trying to connect an ESP8266 01 (Controlled thru an Arduino) as a Client to an ESP8266 setup as an Server via TCP with AT-Commands. But as soon as I send the command "AT+CIPSTART" the response is "Link type Error". The SDK version is 2.0.0.

I have tried it with AT+CIPMUX on 1 and 0 and with every Id but the response is always Link type ERROR Left is the Server / On the right the Client enter image description here

Edit: Some random times after a couple of restarts it works but only 3% of the time.

Solution

  • I found the Answer. So what i did wrong was i didn't initialize the AP with AT+CIPMUX=1. That means it wasn't able to open multiple id. So i just deleted the "0," from AT+CIPSTART=0,"TCP".... to AT+CIPSTART="TCP"... and the command worked. You can also just initialize the AP with AT+CIPMUX=1. But now as soon as i send a message it disconnects/restarts and it won't receive the message. EDIT: SECOND PROBLEM IS SOLVED
