4.2 AT Interface

2N® VoiceBlue Next uses the list of AT commands derived from the standard AT set for configuration and monitoring purposes.

The configuration entering commands start with AT%parameter_id.

The configuration writing out commands start with AT&section.

The following list of AT commands is universal and some commands may not be included in 2N® VoiceBlue Next.
