It echoes what I write but does not reply "OK" on "AT" command. Any idea what could be the problem? Startup message is unreadable. Once it sent out "ready". There is no shortcut between RX or TX. Correct voltages (3,3V). If I change the baudrate from 115200 to something else, then it get unreadable characters, just like expected.

I found out that it needs both LF + CR when using terminal programs.
