CC1352R: Frequency Hopping for FCC 15.247(a)

Part Number: CC1352R
Other Parts Discussed in Thread: , SYSCONFIG

Hello,

I have a question regarding example code for FCC 15.247(a) testing for sub 1-GHz testing for my product which uses the CC1352R. Do you have example code available that would allow my device to do the random channel hopping operations? Is it possible to achieve the channel hopping without the device communicating with another device?

I was reviewing the FCC test report for the LPSTK-CC1352R (see link below) and the test setup for sections 3.1-3.3 show the device just connected to a spectrum analyzer. This would imply that the device was set up to randomly hop without needing to communicate with another device.

If another device is required for channel hopping, can you point me to example code that would allow me to do this?

Thanks,

Braydon

Hi,

Frequency hoping can be configured with the TI 15.4 stack.

This can be configured in the SysConfig tool. https://www.ti.com/tool/SYSCONFIG

Choose TI 15.4 Stack and change Mode to "Frequency Hoping"

Regards,

Richard

To expand on Richard's comment, the TI 15.4 Stack provides a FH Conformance Certification Application Example specifically for FCC or ETSI compliance tests related to channel occupancy.

With the 15.4 Stack configured in Frequency Hopping mode, you can enable Certification Test Mode, which configures the device to join the collector and transmit back-to-back frames.
