Rev. 0.1

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)

Options:

PB1: switches to TX state

PB3: switches to Ready state

PB4: resets PER (only receiver’s PER will be reset)

PB2 + PB4: switches to the configuration menu
