Re: Control of CC2592 (PA) using CC2545

Other Parts Discussed in Thread: CC2592, CC2545

Hi all,

I Interfaced the CC2592 to CC2545 as follows:

PA_EN      pin to P1.0 in CC2545

LNA_EN   Pin to P1.1 in CC2545

HGM         Pin to P2.0 In CC2545

I established a communication between two CC2545 Chips both as transceivers.

I named as Base station and Tag

I used CC2592 at Base station side.

I used simple Balun IC and Chip antenna at Tag Side.

At Base station side to control the PA I follow the following statements in power on time:

    RFC_OBS_CTRL1 = 0x6C;
    RFC_OBS_CTRL0 = 0x5B;
   
    OBSSEL1       = 0xFC;                            /* P1_1 -> LNA_EN*/                          
    OBSSEL0       = 0xFB;                            /* P1_0 -> PA_EN  */

  I given HGM pin to the GPIO pin in CC2545 and I kept high on this pin.

I did the above statements in firmware during power on time only at base station side.

Is it Right way to control the PA or not?

What I have to do to get high range(distance)?

  • Your question indicate that you don't get the performance you are expecting.

    Have you checked with a logic analyzer or similar that the control signals are set correctly?

    Are the chip antenna correctly tuned and have you implemented the CC2592 according to the reference designs?
