i use bluenrg2 as main mcu , to control a ac 220v ac contactor , the main logic is
bluenrg2 -> Optocoupler -> DC 12V relay -> AC 220V ac contactor
If i open/close, the bluetooth will disconnect and will crash very often. Is it not suitable for my case

Start by looking carefully at your supply lines:

could you help me to check the schematic？

You'll have to post the schematic if you want people to check it.
And it's not just about the schematic, the layout is also important - so you'll also need to post some good, clear, in-focus photographs of your setup.
