3.2 Software Architecture
There are two possible software architectures:
1. Host-less mode (application processor): customer application runs on the BLUENRG-M2SA
module. Many sample projects are available in the Development Kit.

2. Hosted mode (Network processor): the module is configured as network module controlled by
an external host connected via SPI or UART. A project named DTM is available in the
Development Kit that configures the BLUENRG-M2SA module as a network module.
