No TeenAstro responses by Wifi some hours later

[MasterPIC]

Hi,

I'm having systematically no responses by Wifi some hours after connection has been established.
If I try to reconnect by ASCOM I get no response or a brief connection after which the issue occurs again.
If I reboot the WiFi module by SHC then connection can be established again.

Adding
WiFi.setSleepMode(WiFiSleepType::WIFI_NONE_SLEEP);
didn't help.

I'm using TeenAstro as a client connected to a router. The issue occurs on several routers. I'm tempted to think that as soon as a disconnection occurs it automatically reconnects but "not properly". In this case maybe an ESP reset could solve the issue.

I'm making other tests.

A simple ping makes it possible to reconnect by ASCOM without the need for an ESP reset.
So as a workaround I think a periodic ping by any client on the lan should work. It should probably keep connection alive with no need to reconnect by ASCOM too. I'm going to check...
Anyway I think something is to be fixed on the firmware side to solve the issue radically.

Hi Armando,
Great work please keep me informed if you find something!

Hi Charles,

I confirm the issue can be solved by a periodic ping. I'm not at home but also by using a smartphone as hotspot, to connect TeenAstro to, I see after about 2 hours the controller doesn't answer to any command.
I tried to add a periodic ping to the ASCOM driver and it seems to work.
I mean to point out that the issue seems not occurring if the controller is set as an hotspot.

Could you share your changes in the ASCOM driver

Hi Charles,

with latest firmware I'm having no disconnection issues. But I'm currently testing it by a different router. And I see there are some parameters that can be involved (GTK rekeying and probably also station inactivity limit - both in seconds).
I'm trying to reproduce the issue unsuccessfully.
Anyway if you are currently able to reproduce the issue you can save the following lines in a bat file to execute it (by Windows) to periodically ping the device and check if it works also in your case. You should obviously edit the IP address.

@ECHO OFF
set IPADDRESS=192.168.0.2
set INTERVAL=300
:PINGINTERVAL
ping %IPADDRESS% -n 1
timeout %INTERVAL%
GOTO PINGINTERVAL

Please let me know the results.

Hi Charles,
feel free to close the issue if you also aren't able to reproduce the issue.

Thanks
Armando

Could you retry with version 1.6?
