Sean For standard (generic) firmware, you can typically upgrade to the latest version directly. However, please note that there may be significant version differences between our custom firmware and the generic firmware.
To ensure a smooth upgrade process, we strongly recommend sending us your module's current version number (obtained via the AT+VER command) for confirmation before proceeding. This allows us to verify if you are currently using a custom firmware version.
