I found the following on https://github.com/esp8266/Arduino/blob ... ference.md:

Code: Select allESP.getCycleCount() returns the cpu instruction cycle count since start as an unsigned 32-bit. This is useful for accurate timing of very short actions like bit banging.

Does that help?

Yep that's it, thanks! I forgot where I saw it.

Will try the coming week to replace the current pulse-timing using micros() with getCycleCount and test if this makes my code more reliable in receiving 433Mhz pulse trains.

Same result here, did not work for me either. Attached my RF receiver to ESP8266-GPIO2 and changed the sketch accordingly.

Update 25-07-2015.
After installing the Latest Stable release (dated 23 jul 2015) from ESP8266-Arduino I re-tested the ShowReceivedCode (from RemoteSwitch) and this works now!!

Also tried the ShowReceivedCode example (from NewRemoteSwitch) but had no success there (yet).

The reception of 433Mhz signals using the RCSWITCH library also works after installing the latest Stable with Boards Manager. Also see:

Also success here with the latest stable version of ESP8266-Arduino
