Unfortunately there is not. An external processor could interface to the part using the peripheral UART interface.
So this module can only be used with AT commands via UART ??

The part is primarily designed to run self contained in embedded mode as the stack, drivers, patches, etc. are integrated into ROM. I believe there is also close to 30K in RAM for the application to run on the internal CM3. The AT command set is not supported by default.
