AT Command Trigger Questions

S2E Module WIZ550 Series
1

Hi,

I have 3 questions please, :mrgreen:

1- When we disable the AT command trigger, means that we send the AT commands right away? Without the 2B2B2B before?
2- If we do use the trigger, what is the 500ms time? We must wait 500ms (after the 2B2B2B) before send a command the AT command?
3- Finally… The hardware trigger pin… As the same purpose of the Command trigger, but pulling the pin low ?

Thanks in advance.
