I am presently using one of the "nodemcu-master-14-modules-2016-02-25-04-41-19-float" firmware. I am unable to perform the atan() operation. It comes back with the error of "attempt to call field 'atan' (a nil value)"

My research on the internet points towards the error of it being a firmware issue. Does anybody has any recommendation?

May the "Force" be with your ESP8266.

Same answer as before.
