OBK 1.18.223 Causes 60s Reboot Loop on BL602 + BL0937 Smart Plugs, Works on LN882H/BK7231N

Hello,

This week I updated my smart plugs from OBK version 1.18.207 to version 1.18.223.

I've noticed that OBK no longer works on smart plugs with the BL602 chipset when used with the BL0937 chip.
As soon as the BL0937 driver is active, the device restarts after exactly 60 seconds.

I also have some smart plugs with the LN882H and BK7231N chipsets, which I also updated from version 1.18.207 to version 1.18.223.
All of them use the BL0937 chip for energy measurement. The plugs with the LN882H and BK7231N chipsets do not have this problem.

The problem is reproducible.
After downgrading to version 1.18.207, the BL0937 driver works again with the BL602 chipset.

edit:
the same with v 1.18.220.
The problem therefore arose between 207 and 220.

edit:
It seems that the problem exists since 210. With 209, it seems ok.

>>21771103 I have similar restarts with ecr6600 (bl0937) if ping watchdog is enabled, but haven't analyzed yet. I just started to use OBK and the problem occurred after few days, which could match the updates. I disabled the watchdog and have no unexpected restarts. By accident I found in log that the no-ping counter is not reset if it starts to increase.
