Does 8266 support RTS/CTS?

[gebh]

FreeOS SDK ver 1.4

when there are some APs at the same channel in the room. 8266 can not get ip address from AP.even it can get the ip ,it will drop the packets frequency.

I catched some wireless packets,and found that 8266 will not send RTS packets to request the chennel.

Does the 8266 support RTS/CTS mechanism? If it do ,which API can open it?

This seems more like a hardware issue to me.
You should use the AT command firmware to see if you still get unstable behavior. If you still do with the latest AT firmware, it has to be your antenna or lack of decoupling, something like that.
A bad crystal also seems to do it.

What hardware are you using? Is it custom?
