WifiGateway crashes after 1 or 2 days

[kr0815]

Any ideas how o solve that problem ?
I built a WifiGateway, after 1 - 2 days, it crashes, i can´t reach it through telnet
But a ping is still working.

As it tkaes that long, it´s not that easy to find the problem

Is there any debug feature ?

@kr0815 best debug option is to connect something to the serial port (before the crash) and watch the logs.
I've seen similar behavior on a regular Ethernet getaway, so not sure if it's really WiFi gateway related.

Hello Yveaux,

i tried to debug with serial connected, but

for hours only that:

then not responsible, no fault message

after waiting for a while i get

Googled, this came up.
Here they say it's related to the maximum simultaneous socket connections to the ESP, which is set to 5 in hardware.
Could it be that you open more than 5 sockets simultaneously?

[kr0815]

Thanks a lot for your help, it´s really frustrating

unfortunately, there are notr more than 5 connections, only my FHEM - installation and me playing around with one, max 2 instances of putty

but as i´m experimenting with it right now it looks like there is a problem with the radio

I tried re-pluging power many times, sometimes i get in in a state where it says "radio init ok", but doesn´t receive messages

I re-checked all the wires (only 10K Pull-Down at GPIO15 , the other lines to Radio are in Mega-Ohm Areas, so no wrong resistors on my ESP-Board)
I tried to add small / large capacitors to the Vcc Line
I swapped the NRF2401 - 3 different batches now, which even look different.
I swapped the wall-wart to a regulated laboratory power supply
--> all the same result

I have about 5 of these ESP-Boards running with ESP-Easy since weeks, so i can´t imagine it´s a fake ESP-Unit ?

Any further ideas what to try ?

It could still be that 5 or more connections are open simultaneously, when e.g. a connection is dropped and not nicely shut down before a new one is opened.

[kr0815]

Maybe you are right
I set up two gateways, only one is connected to FHEM, now i swapped them in FHEM, the connected one crashed
I´ll ask the FHEM guys for help, but as long as i´m playing with putty, is there any command to check / close connections ?
Is it ok just to close putty, or should i send something to close the connection ?

[Yveaux]

@kr0815 Could also be caused by the ESP side, keep that in mind. Maybe search around for 'closed connections' w.r.t. ESP.

[kr0815]

Sorry, this i don´t understand ? What do you mean wth by the ESP side ? Changes in the ESP Code needed ?
The more i think about it, the less i know...
WHat causes the Wifi Gateway sometines after replugging power to say radio init ok, but not receiving messages ?

I mean that when a connection is disconnected abruptly, the socket connection might also not be closed correctly on the ESP side.
It can go wrong on either the server or the client side; I don't know.

[kr0815]

I still have the same problem, it worked now for about 5 days on the workbench, brought it to the final desination, crashes after some hours

But i always could still ping the ESP

What i wonder most about is, that sometimes when i replug the power it says radio init ok, but it doesn´t receive messages
( i see on other gateway that messages are definetly sent)

Is there any possibility to restart the gateway remotely ? Or only chance to replug power ?
Could it be it´s a problem with the initialization of the radio ?

Is it maybe because in my set-up, the gateway is only receiving, never sending anything ?

The gateway lays avbout one meter away from a raspberry (no wifi) , but i can´t imagine that causes the problems ?

Any help / ideas welcome.

[kr0815]

i investigated further:
i have 2 gateways, both dev version, one from today, the other one about 2 weeks old

I tried the relay sketch (newest dev version) - gave it an ID trough my ethernet gateway
--> directly after connecting the relay sensor both ESP gateway crash - no fault messages in serial monitor

DId anybody try the wifi gateway together with a repeater ?
