This command is valid only in TCP client mode & “data pass-through mode”.
This is the timing for the module connecting to the TCP server. If it is 0, it will connect when power on.
If it is 1, the module will establish the connection establishment when receiving the first package of data
from the serial interface. When connection established, the data will be sent to the TCP server and
module would be in data pass-through mode.
