According to the specification of wifi the beacon frame from an AP should include the "time since epoch" so that will do me. If the time is incorrect then I will have a button to ignore and find next SSID but most APs now use NTP and have the correct time set.
I mostly like to spend my time with assembler or machine code on PICs but anything to do with Ethernet gets horrible without a higher level language so I reckon best thing is C or C++ which I am pretty abysmal at. I normally get by with stealing bits of code from here and there on the Internet but I can't find what I need.
So, much reading and playing lets me programme the ESP8266. I did start with the Arduino method but it is not as complete in the libraries as the original SDK and it does not have a promiscuous mode which I believe I need to get the beacon frame.
Starting with the samples that are available I have tried going backwards through the header files to see where I can get access to the raw packet data that I can parse the "time since epoch! out of but I cannot find it, I get hopelessly lost with lots of files open trying to follow them through.
Any pointers please.Statistics: Posted by Mjolinor — Wed Jan 13, 2016 4:13 pm
