flash on sonoff S20 fail

#1 Post by bruno iemanon » 07 Jan 2020, 21:39

I tried to flash espeasy on sonoff S20.
The flash seems to be succesfull but there is no wifi-connection.

I used flashesp8266.exe to flash different versions of espeasy and espeasy-mega. I also tried esptool.
nothing seems to work. flash is always succesfull, but no wifi.

sonoff s20 version:
S20_EU_V1.3 2017-2-16

what i can read on the chip:

Any idea how i can flash succesfully?

Have you tried setting the wifi credentials via a command?
See the wifikey and wifissid commands: https://espeasy.readthedocs.io/en/lates ... mmand.html
