Hi
documentation says : "This fork of SoftRF now (from version MB151) stores the settings in a text file within the flash memory of the device, instead of an "EEPROM" binary block. The first time the new version boots, it reads the existing settings from the "EEPROM" and copies them to the file."
I noticed, that this becomes true only after an usb connection to windows PC and FAT formatting, as proposed by windows, is carried out. I also had to make 1 change manually on the device using the buttons and Save, to have the settings.txt file generated.
And then it is just really easy. Thanks Moshe.
