Hi All.
Ok It looks like it reliably works when you set the baud rate to 19200 for the esp.
The steps i did to get everything work are ass follows.
1.) Flash AT Firmware to esp-01 (Flash Profile i used marked as : Flash size 16Mbit: 512KB+512KB)
2.) Start serial interface on relevant com port at 115200, 8,1,N,N
3.) issue AT command “AT+CWMODE=3” (in putty yo have to press enter then CTRL+J"
4.) Issue AT command “AT+CIPMUX=1”
5.) restart ESP-01
6.) change baud rate with either command “AT+UART_DEF=19200,8,1,0,0” or “AT+IPR=19200”, Only one of them will work.
7.)Make sure that Arduino has the correct baud rate for the ESP-01.
Also to help others out in the future i’ve created the following repository with the firmware, programming tool, instructions, and settings to get the ESP-01 working.
