Offline mode requires users to set secrets values (which are not used) before auto-config kicks in.

[tyeth]

We need the offline mode to not ask you to update the secrets file before auto config kicks in, it’s not clear to a user that it needs to happen, and is a legacy of Online mode.

Here, we create the filesystem, potentially including the default secrets.json and config.json files:

Adafruit_Wippersnapper_Arduino/src/provisioning/tinyusb/Wippersnapper_FS.cpp

Line 141 in 5564777

if (!MakeDefaultFilesystem()) {

If we write to the secrets.json file for the first time, we'll raise the error you are seeing here:

Adafruit_Wippersnapper_Arduino/src/provisioning/tinyusb/Wippersnapper_FS.cpp

Line 159 in 5564777

HaltFilesystem(

Whats difficult about modifying this, at the ctor stage, is we aren't yet certain if we're in online or offline mode.

So, a solution may be to remove the check here:

Adafruit_Wippersnapper_Arduino/src/provisioning/tinyusb/Wippersnapper_FS.cpp

Line 149 in 5564777

if (_is_secrets_file_empty) {

and instead rely on the check for default values within the ParseFileSecrets() function. That function is called within WipperSnapper_V2.cpp, after the configuration file is parsed (and control is returned from the provision() to connect()

Adafruit_Wippersnapper_Arduino/src/provisioning/tinyusb/Wippersnapper_FS.cpp

Line 605 in 5564777

// Validate the config struct is not filled with default values
