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.

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)
PB3: switches to RX state
PB4: resets PER (resets both the receiver’s and transmitter’s PER)
PB2 + PB4: switches to the configuration menu
All LEDs blink together
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
LED1 blinks
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).
