The FW maintains a checksum over the config data to detect if the structure of this data has changed with a new FW version. It is however good practice to clear the config data to be absolutely sure no old data remains possibly causing problems. This can be done with the CONFIG/MORE/CLEAR CONFIG command, enter 1234 as the requested confirmation. After clearing the config the tinySA will automatically reset--
