Bluetooth Module for Tiva C Series Launchpad (TM4C123G)

Recommended Posts

Hello,

 

I am starting a project to record certain medical measurements (pulse, temperature, ecg) with various analog front ends and then use the Tiva C Series to send that data over Bluetooth to a mobile device.

 

I am looking for advice on choosing a Bluetooth controller. I had originally purchased the EDB-BLE by Emmoco but soon realized LE is not efficient for continuous streams of data (ecg) and the 8051 controller requires specific IAR tools.

 

The requirements I would like of this recommended Bluetooth controller would be:

1) Evaluation board available with PCB antenna

2) Availability of Bluetooth stack

3) Ability to program with gcc (not proprietary tools)

 

Please let me know if I am overlooking anything too.

 

Thanks

The http://www.ti.com/product/cc2564 (also look at the cc2567 and other in the series) have an evaluation board and has the propietary one licensed from Stonestreet One and also has open source one here: http://code.google.com/p/btstack/source/browse/#svn%2Ftrunk%2Fchipset-cc256x which has been ported to the msp430 but has a guide on how to port to other chipsets, also it has licensing options for certain chips if needed, here is an excerpt from the homepage

"On embedded systems, a minimal run loop implementation allows to use BTstack without a Real Time OS (RTOS). If a RTOS is already used,
BTstack can be integrated and run as a single thread. The source repository provides ports for different MSP430 development boards.
Other platforms can be targeted by providing the necessary UART, CPU, and CLOCK implementations."

Thanks for the reply. Will the evaluation board (http://www.ti.com/tool/cc256xqfnem) work with the Tiva C Series launchpad. I notice that the software stack works with ARM M4 which is great. But the documentation only specifies compatible boards:

"The CC256x QFN EM board is intended for evaluation purpose and works with Texas Instrument’s Hardware Development Kit such as MSP-EXP430F5529, MSP-EXP430F5438 or EK-LM4F232."
