BK7238 won't connect to Wi-Fi after rebooting the router.

[Malaysk]

Firmware:

• Version 1.18.286
• Device 4-key switches
• Chip/model: BK7238
• Device config?

Hello. I'm having a major WiFi problem with switches running the OpenBK7238 firmware. I have five 4-key switches running the OpenBK7238. If the power goes out in the apartment, the router also turns off, of course. After the power is turned back on, the router takes about 2-3 minutes to boot up until the WiFi network appears. After this, all the OpenBK7238 switches don't connect automatically to the WiFi, and their connection status lights continue to flash constantly. This can continue indefinitely, and they never connect to the WiFi. I have to open the glass panel on all the switches and briefly disconnect the circuit board. After that, they connect to my WiFi network. All other switches running the BK7231T and BK7231N don't have this problem! I've tried almost every firmware version for the BK7238, but nothing helps. The latest firmware version, 1.18.286, is currently installed. Please help me with this big problem for me. I tried setting a static IP address, but it didn't help. I also enabled and disabled fast connection in the WiFi settings, but that didn't help either.

There was ping watchdog feature, but it's no longer present in main builds.
I noticed similar thing with bk7231n. Router logs shows my device trying to connect, and never completing connection.
For me, I made a work around based on mqtt. The scripts restarts the device if mqtt is not connected for more than an hour

alias check_mqtt if $MQTTON==0 then "setChannel 31 $CH31+1" else "setChannel 31 0"
alias check_reboot if $CH31>=12 then reboot else "echo fine!"
addRepeatingEventUID 300 -1 31 backlog check_mqtt; check_reboot;

it was lost in a big space-saving exercise https://www.elektroda.com/rtvforum/viewtopic.php?p=21654657#21654657

not sure if consideration for re-enablement happened https://www.elektroda.com/rtvforum/viewtopic.php?p=21654701#21654701

Its unclear what the intention was. There is two defines ENABLE_HTTP_PING which is enabled and shows (now) pointless ping watchdog UI, but functionality is under ENABLE_PING_WATCHDOG which is not enabled.

Thank you so much for sharing this workaround. Sorry, I'm not very familiar with the rules.
If I understand correctly, I need to create an autoexec.bat file and paste your code into it, then reboot the device. Are these universal rules? Will they work for my switches? I'm really fed up with this problem and am really looking for a solution. Or do I need to change something in this code? Thank you.

Code is fine as long as you are not using channel 31 for something else. you need to be using mqtt though.
It can be put into autoexec.bat or its easier just to put it as startup command.
