Hi

I am having some ESP8266 devices.

Used them with static and dhcp IP adresses.

problem is they can not be pinged sometimes.

arp-scan does not discover them reliable.

there are some known issues....

anyone having a solution or reliable workaround...

Thanks T

boards package version is not SDK version.
SDK are the base libraries for the esp8266 provided by the manufacturer
you didn't read the issue I linked?
