Bluetooth Wake-up radio/receiver

Gabor Petkov

Dear TI support Team,

I am looking for an integrated SoC that has the ability to communicate over Bluetooth, and capable to wake up from deep sleep mode upon a Bluetooth signal. 

The use-case is smartphone send Bluetooth packet or search for devices, this activates the wake-up radio module that generates an interrupt or wakes up of the main CPU and the Bluetooth module. I can not have the Bluetooth module on listening mode all the time as consuming too much power.

Thank you for your suggestions and help in advance.

    Hi Gabor,

    The typical use case you describe is a device operating as GAP Peripheral and advertising with a high latency. Once the smartphone need to connect, it scans and connects with the device. CC2642 is a good device with Bluetooth low energy support.

    Dear, J Lindh,

    Thank you for your advice,  how ever I more like to look for something that is only on when a bluetooth device tries to connect to it. Advertising data is not an option for me, as the application need communicate only on demand. Oce a day or less frequent. Considering this would you suggest something , that is the reason I mentioned  wake up radio or wake up receivers.

    Kind regards

    Hi Gabor,

    There is no such feature in BLE, unfortunately. Out of curiosity, what is your energy budget?

    Hi J Lindh,

    Let me apologize for the late reply, 

    My energy budget is very low, near-zero or battery-less with energy harvesting system attached to it. if you do not mind that I found a SOC called Atmosic M2 and M3 they do have features I would need but I hav not found where could I purchase them. Alternatively, I would like to use TI product as I have good experience with them.
