What I want to achieve is to send these event records to ESP-8266 via serial port as they occur.
The ESP will then Add a Date/Time stamp (Date/time read from SPI RTC) and save it to current location in Flash. The ESP then needs to check if internet is available and if it is then transfer any records from the Flash to the internet. If not then check again later and repeat.
I am looking for any links to documents that may help put this project, or part of it together.
Thanks
Regards
Dave
