This example demonstrates how allocates and handles the custom |
||||
configuration for the Sketch. |
||||
When Sketch stores the own configuration data in the EEPROM, it must |
||||
avoid conflict with the credentials stored by AutoConnect. |
||||
AutoConnectConfig::boundayOffet designation helps with the conflict, |
||||
but it is inadequate. Sketch uses AutoConnect::getCredentialSize to |
||||
get the size of the actual EEPROM area that should be handled for the |
||||
own custom data I/O.
