Creating a custom profile from simpleBLEPeriperal

Other Parts Discussed in Thread: CC2541, BLE-STACK, CC2640

I'm am new to BLE development and I use cc2541 for the purpose. Previously, I have modified the HidEmuKbd example to emulate a key press on a keyboard when a key on my custom circuit was pushed. Now I want to create a custom profile so that data can be passed back and forth between cc2541 and the smartphone/PC etc. After a bit of searching, i understood that the best way to do this is to modify the SimpleBLEPeripheral example and make use of services, characteristics,attributes etc.

Now I would like to know what exactly the SimpleBLEPeriheral does and which part of the code i have to modify so that I can pass data to the connected device and back. Say I want to pass the light intensity from an LDR connected to cc2541 to my phone or activate an LED on the cc2541 when I push a virtual button on my phone.

Thanks.

    Hello Sreedev,

    Please go through the BLE SW Developer's Guide, which is in the BLE-Stack 1.4.1 SDK. This will give you a good intro to BLE and the SimpleBLEPeripheral project. For custom profile, there is some guidance on the TI BLE Wiki, including SimpleLink Academy, however this is for CC2640. The concepts for custom profiles is the same for both CC254x & CC2640.

    Best wishes
