3.2.5 Command Issuing Timing

The chain Command -> Response shall always be respected and a new command must not be issued

before the module 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 module.

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 +IPR command.
