Note
If you use the %AANNTTCCFF command to change module configuration, the new configuration code is
stored into EEPROM immediately.
The configuration code includes the module address, module type, baud rate code, checksum enable/disable
code, calibration code, power-on value and safe value.
The EEPROM data of a CB-7080 can be read an infinite number of times, and can be written about 100,000
times maximum. Therefore, you should not frequently change the configuration code for testing.
The $AA2 command is used to read EEPROM data only. You can send this command to CB-7080 module
without limit.
