Is there any way to disable or bypass CSMA/CA in esp8266? I don't want my packets to wait for channel to be clear. I want them to be transmitted at predefined time. If it is not possible to completely disable it, can we change random back-off period (so that we can transmit packets sooner rather than waiting for long time)? If not in esp8266 is there such functionality (of disabling CSMA/CA) in any other IC implementing WiFi protocol in 2.4 GHz band?
Edit: http://www.osbridge.com/download/OSBRiDGE_5G.pdf allows disabling CSMA/CA but it works in 5 GHz band. MikroTik also allows disabling CSMA/CA https://wiki.mikrotik.com/wiki/Manual:Interface/Wireless.
