#54074 I've got several ESP8266 ESP-12 Ai-Thinker modules in station mode that after a couple days fail to respond on their IP addresses. The first day or so they work perfectly. Then, usually after about 36 hours, fail to respond anymore. I have all of the tie-up resistors and a capacitor at the power points. When I do an AT+GMR, I get:
AT version:0.21.0.0
SDK version:0.9.5


The actual error I get is:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.0.9:2500.

Is there a code upgrade for these and if so, where can I obtain it?

#55427 I tried this with a different ESP8266 which is an ESP-01 which has "AI-Cloud inside". After about 18 hours I tried to connect to it and got the same error. Should I be sending it a command occasionally? Is it possibly sleeping after some time passes? If I try to send it commands on the serial port, it responds just fine. It's on the network side that it stops working.
