2.4.1.3. TX State

In TX state the node sends packets to the receiver repeatedly with half second timeout including the node address.

After sending the packet, transmitter waits for ACK packet until the half second transmit timeout. The transmitter

recalculates its PER after receiving the ACK packet or timeout occurred.

State display:

All LEDs are off by default

LED1 blinks if packet sent

LED2 blinks if ACK packet received

LED3 & LED4 shows the actual PER (see Table 3)

Buzzer informs about actual PER (see Table 3)

Options:

PB3: switches to RX state

PB4: resets PER (resets both the receiver’s and transmitter’s PER)

PB2 + PB4: switches to the configuration menu

2.4.1.4. Configuration Menu

The user can change demo parameters in the configuration menu.

State display:

All LEDs blink together

Options:

PB1: switches to address configuration menu

PB2: switches to frequency configuration menu

PB3: switches to data rate configuration menu

PB4: switches to modulation configuration menu

PB2 + PB4: restores defaults

2.4.1.5. Address Configuration Menu

The user can set new node address in this menu state.

State Display:

LED1 blinks

Set the Configuration:

Set the node address on the switches in binary format.

Be aware that the direction of the switches is reversed than the bit locations in the binary number (LSB

representation).

Example: If the required node address is 10 (binary 1010), set SW2 & SW4 to on and SW1 & SW3 to off

(see Figure 4).
