5.8.5Java Commands

There is a small set of special Java AT commands:

•AT^SJRA, start a Java application

•AT^SJNET, configuration of Java networking connections

•AT^SJOTAP, start and configuration of over the air provisioning

•AT^SJSEC, security configuration

Refer to the AT command Set [1].

5.8.6AutoExec Function

Under Java, the AutoExec function’s AT command execution has some restrictions (see [1] for details on the AutoExec function). If an AT command is executed, neither URC nor command response are indicated to the Java application. Therefore, it is recommended to use the AutoExec function under Java only with commands that shut down the module, e.g., with AT+CFUN=0,1, as a watch dog. Any other AT command execution should be implemented with Java means and the ATCommand class.

5.9System Out

Any output printed to the System.out stream by a Java application can be redirected to one of the serial interfaces, a file, a "NULL" device (i.e. the output will be discarded) or a UDP socket for using the debugger from an IDE. The configuration can be done at any time using the AT command AT^SCFG (see [1] for details) and is non-volatile.

5.9.1Serial interfaces

System.out can be written to any of the serial interfaces ASC0, ASC1 or USB. If System.out is redirected to one of the interfaces used for the Java CommConnection, the interface will be shared between System.out and the CommConnection. This will result in mixed output, if data is written to the CommConnections OutputStream and something is printed via System.out at the same time.

Using System.out and CommConnection on the same serial interface may be done if a device connected to the serial port is only transmitting data to the module. It is recommended to ensure already in the HW design that output from the module cannot be transferred to a con- nected device.
