> 5.8.4 | Configuration of Serial Interface

> While a Java application is running on the module, only the AT Command API is able to handle AT commands. All AT commands referring to a serial interface are ignored. This includes the commands:

> • | AT+IPR (sets a fixed local bit rate)

> • | AT\Q1, AT\Q2 and AT\Q3 (sets type of flow control)

> If Java is running, the firmware will ignore any settings from these commands. Responses to the read, write or test commands will be invalid or deliver „ERROR“.
> Note: When a Java application is running, all settings of the serial interface are done with the class CommConnection. This is fully independent of any AT commands relating to a serial interface.
