... what is the best procedure to upgrade without losing the settings in the files?

Hi Marco,

Usually i try to use this rule:
- If on the new software, only the build number was changed , usually you can use the Config_Options.h and Credentials.h files from previous build.
- If the software version number was changed, its better revise the Config_Options.h and Credentials.h on the new software, and copy the corresponding values from the previous version.

Ex:
- Upgrade from P2ESP8266_RX_v3.1_b010 to 2ESP8266_RX_v3.1_b012 -> Usually you can use the Config_Options.h and Credentials.h files from previous build.

- Upgrade from P2ESP8266_RX_v3.0_bxxx to 2ESP8266_RX_v3.1_xxx -> Its better revise the Config_Options.h and Credentials.h on the new software.

In any case when using config files from a previous version, after open the software on the IDE, its highly recommended that you edit the info on the top of the Config_Options.h file.
Ex:

// --------------------------------------------------------------------------------------
// WeatherDuino Pro2 Compact RF Receiver - Version: P2ESP8266_RX_v3.1_b012
// Start of user configurable options
// --------------------------------------------------------------------------------------
