Which commands? AT commands?
AT will show "ready" when the AT firmware is ready.

Dear Her Majesty!

Yes, I use AT firmware.

But otherwords my problem is, how long I wait before start setup ESP?

I cannot bind to firmware, beacuse at mass production I can use different AT firmeare version.

Thanks for advise, kzsolt
