Serial Timing:
Each serial command is made up of a sequence of data bytes. Some
commands are single byte and others are multiple bytes. When a
command is sent, the module will reply back with a single acknowledge
byte called the
command was understood and the operation is completed. It will take the
module anywhere between 1 to several milliseconds to reply back with an
ACK, depending on the command and the operation it has to perform.
If the module receives a command that it does not understand it will
reply back with a negative acknowledge called the
For example, if a command has 5 bytes but only 4 bytes are sent, the
command will not be executed and the
another byte is sent before trying to execute the command. There is no
timeout when incomplete commands are sent. The module will reply back
with a
make sure the command bytes are sent in the correct sequence.
