ATO/AWC Level Control Malfunction - Profilux 4

[otimer]

Hello Vinny.
Yes, I understand that GCC and the update tool cannot be connected at same time. So I have run always one by one.
About the way to identify level sensors, noted and many thanks.
After replacing the level sensors, ATO/AWC is perfectly working.
I attached accidently wrong image that has different IP address on client mode and access point mode. Sorry about that.

In the meantime, I'm still trying to set wifi connection.
One important point that I was missing in performing wifi update tool was the reset p4 (power cycle) prior to each step of the update tool.
I completed update the wifi module strictly as per your instructions as follows.
Running update tool -> checked COM port and P4 connected -> reset p4 (30s) -> blank chip clicked -> command prompt open/closed -> reset P4 (30s) -> Reprogram filesystem clicked
-> command prompt open/closed -> reset P4 (30s) -> Start clicked -> command prompt open/closed -> reset P4 and then closed the tool.
And then open GCC and connect p4. I entered all the IP parameters in the communication page and devices - save changes. I disconnected for a while and reconnected.
The image below is the screen after reconnection. Also wifi indicator on the P4 is working.
I tried to modify IP address (last digit), the current IP comes up same as entered IP address.

But, I cannot connect MyGHL, and I got a pop-up message “Connection Failed” on Crome as well as on my Android phone.
The pop-up message is slightly different on the I.E but same meaning.
What is wrong in my procedure? Please advise me how to resolve this problem.
I very much appreciate your help.
Regards,

Son
