Describe the bug
When i got first MINI+ printer the delivery was in two packages, printer in one, ESP01-S module in the other one, which arrived day later.
Because i didn't want to wait for assembly, i just used some random ESP01s module i had around. After some time i had opportunity to compare how the networking works between two similar MINI+ printers, and third MK4. And the module i used in the first printer, and modules which are added both to the MINI+, and MK4 printers for now.
MINI+ (with delivered ESP01s module) had issues with receiving files while printing, 403, and some other random stuff...
Because i had other well working MINI+ i just changed the module, while i had more of them around, and all problems gone...
So i also replaced the module in MK4, (here there were no problems with transfer, expect it was slow) and MK4 after change has better transfer. And MINI+ transferring data faster now, and no issues at all.
How to reproduce
MINI+ with prusa delivered ESP01s module randomly refusing to get files over WIFI network while printing.
MK4 slow WIFI performance in general.
So i tested other module, and the difference seems to be related in flash memory used in the board?, those which perform better are with other chip on board.
So the prusa attached module is:
Z DA2314 25VQ80ATIG P3L015 and this module sucks with MINI+'s i tested, and it's slower with MK4.
while the other one i tried "random" (in the photo below) works much better, flash memory signature: T25S80 PBTTq3 PPJ806 besides it's more or less similar ESP01s module...
Expected behavior
Transfer rate is better, and stable in case of MINI+ with the supplied ESP01s module. MK4 can be bit faster with other module.
But probably more testing is needed.
This issue has been flagged as stale because it has been open for 60 days with no activity. The issue will be closed in 7 days unless someone removes the "stale" label or adds a comment.
