Everyone,
I have the Wemos D1MiniPro at 16MB of memory. I have been trying to upload my script that is at 11,220 Bytes (12,288 on disk).
Anyone know why this is a limitation of the Wemos / ESP8266. I have tried multiple Chips and each one gives off this error. Thank you for your feedback. My assumtion is regardless of my Chip being handle to handle 16 Megabytes that it is perhaps the firmware that is only allocating X Amount?
I am using a firmware build from NodeMCU's cloud service.
