RTOS/CC2640R2F: CC2640R2F

Tool/software: TI-RTOS

Hi,

we made an application including the BLE CC2640R2F MCU. The need is to receive some data from known Beacons and to communicate with a smartphone.

For power saving purpose I need to know if it is possible to set the BLE to SCAN only one of the 3 advertising channels. I know that the Bluetooth specification does not allow to scan only one channel and that probably TIRTOS does not implement this opportunity, but I want to know if there is a solution to bypass this limitation (also going in a deep level of programming), no matter working out of specification (for now).

I know that with smartRF, for debugging purpose, is possible to scan on a single channel, so I suppose there is a method to replicate this behavior inside my code.

Thank you very much for helping me!

Best Regards

As I know, TI BLE Stack doesn’t allow only scan single channel.

Hi Simone,

Each beacons should have unique identifiers at advertisement packets. You can use this unique identifiers to distinguish multiple beacons.

Hi, thank you for your reply!

Yes this is ok, but the fact to scan only one channel was to save power, because I have to communicate with 3/4 known beacon (also mounting the CC2640) and it is not usefull for our application to scan all the 3 channels.

If you know a method to set the CC2640 to scan only one channel let me know!

Thank you!

Hi Simone,

It's not allowed to scan only one of the advertisement channel per the core specification.
