2.4.1. Menu States
2.4.1.1. Ready State
In Ready state the demo waits for command.
This is the default state of the demo. The demo starts in Ready state after switched on and goes to Ready state
after leaving the configuration menu. PB1 can push the demo to RX state.
State display:
LED3 is on
LED1-LED2 and LED4 is off by default
Option:
PB1: switches to RX state
2.4.1.2. RX State
In RX state the node waits for incoming packets with the same node address. If packet is received it sends ACK
packet and recalculates the PER.
State display:
LED1 is on
LED2–4 is off by default
LED2 blinks if packet received
LED3 & LED4 shows the actual PER (see Table 4)
Buzzer informs about actual PER (see Table 4)
Table 4. Packet Error Rate on the LEDs and Buzzer
PER < 1%
PER > 1%
PER > 5%
PER > 20%
