guys,
I have ESP8266-DEVKITC dev board, and it has a dial switch. When I reached in documents, it said its for " Auto Download and Flow Control"
I don't know what that means, can someone please explain that to me?
There's slightly more detail on the Espressif website that says:
Dial Switch
A dial switch used for switching between Auto Download and Flow Control.
- Bit1=OFF, Bit2=ON (Auto Download)
- Bit1=ON, Bit2=OFF (Flow Control)
There's also an extra line in a Getting Started PDF that says:
Bit1 and Bit2 cannot be set to ON at the same time.
Beyond that, there doesn't seem to be much more of an explanation. I did take a quick look at the schematic and assuming I chose the correct design, then this might hold a clue:
If I've got the right switch, then it seems to be mainly about hardware flow control on the serial port.

hey,
Thank you for the reply.
but if I had more explanation about what exactly mean by "Auto Download and Flow Control" and what they do, that would be really helpful 
(and I can't ask from the forum too, cuz the forum was closed https://esp8266.com)
