Address: C8C8CF   <- nRF24 address (3..5 bytes)
Rate: 1	          <- nRF24 data rate (0 - 250Kbps, 1 - 1Mbps, 2 - 2Mbps)
Ch: 121           <- nRF24 channel (0..125)
CRC: 2            <- nRF24 CRC size

Resend: 3         <- resend attempts on error
Delay_ms: 30      <- delay between cmd and resend
ReadCmd repeat: 3 <- seconds (long press "Ok" in ReadCmd mode turn on repeating)

Payload struct: 2,1,1   <- field sizes of send packet in bytes, received packet consists of 1 field with default size 1 byte (int8)
