Cambridge Consultants unveils Bluetooth iPhone apps for mobile
13 March 2012
Cambridge Consultants demonstrated new Bluetooth low energy
(BLE) iPhone 4S applications using CSR’s BLE devices at this year’s
Mobile World Congress at the end of February.
The BLE iPhone app demonstrates the transfer of blood pressure
readings, using the BLE Blood Pressure Profile, while running on an
example single-mode BLE device that could readily be incorporated
into a blood pressure monitor.
Every BLE application faces its own challenges relating to power
consumption, data transfer requirement and constraints of the
smartphone. Leveraging its technical and medical regulatory
expertise, Cambridge Consultants is able to optimise usability for
both the device and the smartphone to meet the needs of the mHealth
For mHealth, both local and wide area communications are required
and with most mobile phone operating systems providing native
Bluetooth stacks, BLE is an ideal technology for integration. BLE
technology is designed for low peak current consumption, permitting
operation via standard coin-cell batteries and permitting battery
life of up to one year.
“We see great potential for CSR’s technology solutions in the
mHealth space and Bluetooth low energy-related applications will
open significant market opportunities,” said Paul Williamson, Health
& Fitness Product Marketing Manager at CSR.
With wireless access to mobile devices becoming the norm, battery
life is a critical concern for any new product entering the market.
Devices for which BLE has been defined typically run from primary
cells and do not need regular charging.
BLE has been designed to provide long-term wireless connection
capability without altering the usability of the devices, and
require low-cost batteries that must power the wireless capability
for very long periods, often until the device itself is replaced.
“We have extensive experience in getting health devices working
with smart phones in a regulatory environment, and we are excited to
showcase some of our work with CSR at this year’s Mobile World
Congress” said Tim Fowler, Commercial Director, Wireless Division at
Cambridge Consultants. “In addition, in recognition of the medical
regulators’ views becoming clearer on using smart phones in mobile
health applications, we foresee imminent and significant growth in
the connected health space. We can help companies navigate the
regulatory and technical issues to get the most out of the emerging
BLE-enabled mHealth technologies.”
