How to compress and decompress the bin file for OTA

Postby GaneshPodPoint » Fri Mar 06, 2020 12:06 pm

Hi there,
I have seen in internet that some people are compressing the bin file for OTA.
Could you tell us that what library should i use to compress and decompress the bin file? and i have seen that it is done in esptool.py while flashing the bin file via serial port.

Thanks
Ganesh

What was the solution?

Ive been curious about this too...it would be nice to not require 5 minutes just to OTA-download a bin to SPIFFS...
