CC2538: how to generate single tone frequency at specific channel? can share the example code?

Hi,

Please refer to https://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/678037/cc2538-constant-tx-on-single-channel-for-ul-approval

Thanks,

what I need is "single tone frequency"  or carrier wave.

like this but need to work on CC2538. A complete example will be the best.

Please refer to here, where it links to examples which can be used: https://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/331305/cc2538-zigbee-low-level-radio-transmission

Notably, the PER example could be re-purposed for continuous wave.

Otherwise, I recommend to use SmartRF Studio 7. This one for sure has a Continuous TX option.
