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)?
