Part Number: CC2650

Hi,

I'm looking to use the cc2650 present on c5545booster pack to transmitt the dsp data to phone for recording via HFP or other means. I've no BLE stack programming experience. Can someone help me providing a stack code for my application. Thanks in advance.

Hi,

We don't provide the service of making customized firmware here. What I can recommend you is to use our SimpleLink Academy training to get familiar with BLE and our software solution.
You can find the SimpleLink academy here: software-dl.ti.com/.../overview.html

CHRISTIN,

thanks for reply, I've no knowledge of stack programming, if not hfp is there any other profile stack that is already available for my purpose?

Sorry, I am not aware of any existing stack that's customized to suit your need.
The SimpleLink Academy provide training on using BLE STACK, you can take a look at it. After those trainings, you should be able to rewrite the program making it do what you want.

christin,

So this BLE stack is maintained at dsp end? meaning it will be executed on the dsp chip right? if so do I also have to do any stack programming at app side on mobile?

No, the BLE stack is maintained by LPRF and the question regarding BLE should be posted here. However, we don't do customize FW. We provide training tools(SimpleLink Academy) for users to get to know our product and SW solution.

You can find all the needed SW and HW design information in the user's guide.
Software user's guide:
www.ti.com/.../sprui92.pdf
Hardware user's guide:

There is CC2650 that runs BLE on the module and C5545 DSP does the wave file playback or audio streaming from line in.
You also need to have a androip app to run the demo.

Please take a look at both software user's guide and hardware user's guide. These two documents answer your questions.
