CC2538: Constant TX on single channel for UL approval

Oliver Zabel

Part Number: CC2538
Other Parts Discussed in Thread: Z-STACK,

Hi, 

we have a customer that needs to have UL approval of one of our products. Now UL wants to have a constant TX on channels 1, 18, 25 for measurement purposes. We gave them our products and said they should control the channels via RF Studio but the refused because they want to have a standalone PCB without PC connection. 

Now my question, is there some example which is doing what UL wants? 

I saw something in Z-Stack ZNP that seems to do it ( znpTestRF() ) but my Version of IAR 7.40 can't open the samples which seem to be created i newer version of IAR (*aarrrrgghhh*).

So, can someone help me with either a hint how to do it or perhaps with the ZNP SW for IAR 7.40 or perhaps someone has a different solution for my problem?

Thank you very much in advance!

Best regards, 

oliver

    You can try to use ZNP of Z-Stack 3.0.1 to set both primary and secondary channel to make it.

    Hi Oliver,

    Have you referred to the ZNP Interface Examples from the CC2530ZNP Mini Kit? This includes a RF Tester project workspace: www.ti.com/.../swrc211

    You might find the CC2538-SW most useful: e2e.ti.com/.../331305

    Please note that channel 1 is sub-1 GHz which is not supported on CC253x devices.

    Regards,

    Hi,

    first of all - thank you very much! swrc272a helped a lot! I modified the project to run without LEDs and LCD. It compiles, it runs - but no RF output. I attached my file - perhaps you can take a look whether there is a major bug....

    BTW we are using the CC2538NF53.

    Have a nice weekend!

    Regrads,

    Oliver

    Hi @all, 

    thanks for your help! I forget to init the BSP so, this was the reason my code was not emitting any RF output - but now it works!

    Best regards, 

    Oliver
