3 Software Development
3.1 Software development Kit
The SPBTLE-1S module embeds the BlueNRG-1 application processor. Refer to the BlueNRG-1 web
page (http://www.st.com/en/wireless-connectivity/bluenrg-1.html) to get access to:
• BlueNRG-1 datasheet
• development kit
• application notes
• user manuals
• tools & software
• design note and tips
Software and firmware should be configured taking into account the SPBTLE-1 specific configuration as
described in the block diagram chapter. In particular the SPBTLE-1 module has:
• 32 MHz crystal oscillator
• 32 KHz crystal oscillator
• SMPS DC-DC converter
• 10 µ H SMPS inductor
The projects provided with the development kit should be customized defining as following:
• HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZ
• LS_SOURCE=LS_SOURCE_EXTERNAL_32KHZ
• SMPS_INDUCTOR=SMPS_INDUCTOR_10uH
3.2 Software Architecture
There are two possible software architectures:
1. Host-less mode: customer application runs on the SPBTLE-1S module. Many sample projects
are available in the Development Kit.
