NOTE: If the user use %AANNTTCCFF command to change module
configuration, the new configuration code will be stored into
EEPROM immediately. The configuration code includes module
address, module type, baud rate code, checksum enable/disable code,
calibration code, power-on value and safe value. The EEPROM data
of I-7000 can be read infinite times and can be written about
100,000 times max. Therefore the user should not change
configuration code often for testing.
The $AA2 command is used to read EEPROM data only, therefore
the user can send this command to I-7000 module infinitely.
