CC2640R2F: Channel selection/hopping algorithm needed for FCC

DanJ

Part Number: CC2640R2F

I'm using the BLE stack (Simple Peripheral) with default radio setup.

The FCC wants an operational description including how frequencies are selected. I assume this needs to include the frequency hopping algorithm.

Does anyone know where I can find this information?

(I've been through the CC2640R2F data sheet, the Tech Ref, the BLE stack users guide, and this forum. But to no avail.)

Hi Dan,

Please review this: http://ti.com/ble-qualification

Joakim,

There is nothing in that document that addresses my question about how channels are selected by the BLE stack?

Channels are selected pseudo-randomly based on a channel map defined at connection creation. There is no Adaptive Frequency Hopping (AFH) feature implemented in our protocol stack implementation. Does this help? If you need more details, I suggest referring to the core specification.

Joakim,

Thank you. That does help. Where did you find it?

I would like more detail. What core specification are you referring to? And what section?

Hi Dan,

It's common knowledge for us who have been working with Bluetooth low energy during the last decade.

You will find more info here:

Oh. Bluetooth Specs. I was looking in the TI stuff. So the channel selection algorithm is in the BT spec. I guess that makes sense. I'll revisit. Thanks.
