3.5.97. MODEM_ANT_DIV_CONTROL

Summary: Specifies antenna diversity controls. Antenna diversity mode is valid for standard packet only. 

Purpose:



Specifies pm detection threshold and GPIO config in antenna diversity mode. 

Property: 0x2049 

Default: 0x80 

Fields:



ant2pm_thd[3:0] - default:0x8 The second phase preamble detection threshold in ANT-DIV mode. Default is set to 8 bits 

threshold. 



matap - default:0 Number of taps for moving average filter during Antenna Diversity RSSI evaluation. Allows for reduced 

noise variation on measured RSSI value but with slower update rate. 

0 = Filter tap length is 8*Tb prior to first PREAMBLE_VALID, and 4*Tb thereafter. 

1 = Filter tap length is 8*Tb. 



antdiv[2:0] - default:0x0 The GPIO must be configured for antenna diversity for the algorithm to work properly. 

0 = RX/TX state: GPIO-Ant1=1, GPIO Ant2=0: Non-RX/TX State GPIO Ant1=0, GPIO Ant2 = 0. 

1 = RX/TX state: GPIO-Ant1=0, GPIO Ant2=1: Non-RX/TX State GPIO Ant1=0, GPIO Ant2 = 0. 

2 = RX/TX state: GPIO-Ant1=1, GPIO Ant2=0: Non-RX/TX State GPIO Ant1=1, GPIO Ant2 = 1. 

3 = RX/TX state: GPIO-Ant1=0, GPIO Ant2=1: Non-RX/TX State GPIO Ant1=1, GPIO Ant2 = 1. 

4 = RX/TX state: GPIO=Antenna diversity algorithm: Non-RX/TX State GPIO Ant1=0, GPIO Ant2 = 0. 

5 = RX/TX state: GPIO=Antenna diversity algorithm: Non-RX/TX State GPIO Ant1=1, GPIO Ant2 = 1. 

6 = RX/TX state: GPIO=Antenna diversity algorithm in beacon mode: Non-RX/TX State GPIO Ant1=0, GPIO

Ant2 = 0. 

7 = RX/TX state: GPIO=Antenna diversity algorithm in beacon mode: Non-RX/TX State GPIO Ant1=1, GPIO

Ant2 = 1.
