SP501E help


I have flashed my sp501e with wled from the web application without error, but when I connect it to the power, I can’t see the wled access point.

should i do something else?


What bin file are used?

i used beta 0.13.0-b2.

flashed without error.


Not a correct version to flash. Try this one WLED-wemos-shield/SP501E_2m.bin at master · srg74/WLED-wemos-shield · GitHub

What memory size your board have?


it has 2MB, i’m using a FTDI to USB F232r @ 3.3v, maybe that it’s the problem?

Try this firmware it’s compiled for 2M SP501E. And better if you erase before you flash new bin

i erase it all before flash it, but then, when finish the flash, i have this error.

Why you flashing this file instead of file from Github?

these file its that you send me, i changed the name.

bin files have been updated check out here WLED-wemos-shield/resources/Firmware/WLED_wemos_shield/v0.13.0-b2 at master · srg74/WLED-wemos-sh
