Route to Market
RF Design or Wireless Application?
●
●
Taking the RF Out of Wireless
Microchip focused on enabling customers
get to market quicker
●
RF Design is a Specialist Field
Too few RF Design Engineers
Module Approach creates a wireless system
design rather than RF Design
Module Approach
Design Engineers focus on their end application
Wireless provided as pre-certified modules
Software stacks to enable faster time to market
Application focused, no need for wireless
expertise

Route to Market
Chip or Module?
●
Profile of a chip customer
●
Very high volume(s), 200K to 300K per annum
MUST have RF hardware experience
Wi-Fi knowledge
Long term revenue goals
Module customer
All Volumes: 100 to 100K per annum
Application focused, no need for wireless expertise
Chip-level customers start with modules
Get an initial product to market
Learn about customer requirements
Generate some revenue
Time to implement cost down chip-level design

What is a LAMP Server…
●
Linux
Apache
MySQL
PHP
A collection of applications, in this case Linux based, providing the Apache Web
Server, MySQL Database and PHP Admin functions to create a dynamic
database driven web server capability
PHP allows incoming data from Web Server to be checked and entered into a
database field. The database can also be checked for any outgoing messages
back to clients.
LAMP Server Implementation
Dedicated Linux implementation
Physical Server
Virtual Server Instance e.g. Amazon AWS
Local Server running as an application
XAMPP,

Serial Cable Replacement

Bluetooth Profiles:
Serial Port Profile (SPP)
Bluetooth Classic SPP Profile Emulates COM port over BT
Cable Replacement Applications
Bluetooth driver on host computer creates a virtual COM port after successful pairing
When COM port is open the Bluetooth connection to the slave is opened
Bluetooth LE or Smart has no equivalent standard streaming data
profile
So is it possible to obtain an equivalent capability using BT LE?
