5.2.4 Command issuing timing
The chain Command -> Response shall always be respected and a new command must not be issued before the
TRIZIUM has terminated all the sending of its response result code (whatever it may be).
This applies especially to applications that "sense" the OK text and therefore may send the next command before the
complete code <CR><LF>OK<CR><LF> is sent by the TRIZIUM.
It is advisable anyway to wait for at least 20ms between the end of the reception of the response and the issue of the
next AT command.
If the response codes are disabled and therefore the module does not report any response to the command, then at least
the 20ms pause time shall be respected.
During command mode, due to hardware limitations, under severe CPU load the serial port can loose some characters if
placed in autobauding at high speeds. Therefore if you encounter this problem fix the baud rate with AT+IPR
command.
