I've recently been given a task with the ESP12-F module. The User SPI is connected to a cortex m4 uC.
Right now I need to accomplish sending a large file (150MB) over WiFi to the ESP8266 and then storing it in some memory connected to the uC. I have never done any wifi stuff before, but here is what I've come up with so far.
I'm using a Websocket for Arduino library. PC connects to ESP8266, sends over file one piece at a time (right now its 8KB per chunk). Then I send it to the uC one piece at a time.
This is fine but sometimes there are errors. Has anyone else done large file transfers like this? The speeds I'm getting are pretty slow and I'm trying to figure out if this is feasible and if its possible to go faster?
Thanks in advance,
