Usage of a Range Extender with Z-Stack

Other Parts Discussed in Thread: CC2591, CC2592, Z-STACK, CC2538

Hello,

I want to use a range extender (CC2592, CC2591) with CC2538 in my design. I will use Z-Stack software and I have the following questions about using the range extender.

1) Do I have to write extra code for controlling the range extender on the Z-Stack software?

2) There are two pins which are LNA_EN and PA_EN on the range extenders. These pins should be controlled by software. So Can Z-Stack manage these pins when the range extender is used ?

3) Is there any compiler option which enables usage of the range extender in Z-Stack?

4) Where is the LNA_EN and PA_EN pins defined in Z-Stack? Which file?

5) How can I configure LNA_EN and PA_EN pins  in Z-Stack?

Best Regards,

Mehmet Cihangir

    Mehmet, 

    1) Do I have to write extra code for controlling the range extender on the Z-Stack software?

    • No, we have already done it.

    2) There are two pins which are LNA_EN and PA_EN on the range extenders. These pins should be controlled by software. So Can Z-Stack manage these pins when the range extender is used ?

    • Yes, they will be controlled by Zstack and the low level RF hardware engine

    3) Is there any compiler option which enables usage of the range extender in Z-Stack?

    • Yes, please look at the Zstack user guide. (CC2591 is available today, CC2592 will be available shortly)

    4) Where is the LNA_EN and PA_EN pins defined in Z-Stack? Which file?

    • They are not, you need to follow the reference design because they are hooked up to pins that are specific to the RF hardware engine. 

    5) How can I configure LNA_EN and PA_EN pins  in Z-Stack?

    • There is not full flexibility here, we recommend that you stay with our recommended reference design.

    Regards,

    Thanks TA12012.

    It is so nice that these pins will be controlled by Zstack and the low level RF hardware engine.

    Best Regards,

    In the question 5, you said that is no full flexibility, I have a custom cc2538, but I didn't respected the reference design, Is there anything that I could do?
    Here is a image of my design, the part of the RF.

    PA_EN and LNA_EN can only connect to PCx pins. I think you have to revise your schematic to make it work.
