BLUENRG-M2Sx
6
 LS_SOURCE=LS_SOURCE_EXTERNAL_32KHZ
 SMPS_INDUCTOR=SMPS_INDUCTOR_10uH
The BLUENRG-M2SP module has:
 32 MHz crystal oscillator
 LDO converter
The projects provided with the development kit should be customized defining as following:
 HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZ
 SMPS_INDUCTOR=SMPS_INDUCTOR_NONE
3.2 Software Architecture
There are two possible software architectures:
1. Host-less mode (application processor): customer application runs on the BLUENRG-
M2Sx module. Many sample projects are available in the Development Kit.
Figure 2. BLUENRG-M2Sx - BLE Application Processor
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-M2Sx module as a
network module.
