Continuous modulated TX CC2630+CC2590 for CE cert testing

Stephanie Werner

Other Parts Discussed in Thread: Z-STACK, CC2590, CC2538, CC2630

Shortly we're going to have products, that use a combination of CC2630 and CC2590 go through CE (similar to FCC in the US) certification tests.

For these we would need a way to send a continuous stream of packets on any chosen channel. Similar to what is possible using SmartRF Studio. However, we can't use SmartRF Studio for this, as there is no possibility to control the CC2590 and measurements would be off. So we need to build a firmware that does this while also using the range extender.

I've read this post regarding the CC2530, where the threadstarter asked something similar, but the stacks and the underlying architecture is (of course) different.

Is there another possibility to do this besides SmartRF Studio or a custom firmware?

If not, are there any API documents available that explain how to do this (in Z-Stack if possible) maybe even examples for code snippets?

Thanks in advance,

stephanie

Have you looked at this design www.ti.com/.../TIDC-CC2650-CC2592-EMK or this wiki processors.wiki.ti.com/.../CC26xx_Range_Extender_Control both explaing what to add to control for range extenders.

Hi Charlotte,

thank you for the links; that wiki page was new to me.

However, we already successfully integrated the CC2590 into our design and got it working using Z-Stack. I probably expressed my questions incorrectly.

For the CE/FCC certification we need our device to send a continuous (modulated or not) stream of data so the inspector can do his EMC tests. I know that SmartRF Studio offers the possibility to do "continuous tx", but for the cc2630 there is no field for enabling the use of a range extender, as is the case for the cc2538. While i am not entirely sure, what SmartRF Studio does in order to run it's tests, i doubt it uses the firmware that is flashed onto the device.

So, we'd either need a way of enabling the use of the range extender in smartRF Studio or add the functionality of creating a continuous wave to Z-Stack (if there isn't already). This is highly important for us, as we are working on a tight schedule to get the certification.

thanks for your efforts. kind regards,

stephanie

Hi Stephanie,

Have you read through the radio chapter in the CC26xx TRM (www.ti.com/lit/pdf/swcu117)?

Cheers,
Fredrik
