-| Byte | Description | Notes |
-| ---- | ---- | ---- |
-| 0    | Preamble | "Q" 0x51 |
-| 1   | Channel ID | channel used for comunication between TX and RX |
-| 2    | Frame type & Payload Length | bits 7-5 defines frame type, bits 4-0 payload length |
-| 3    | Packet ID | |
-| 4 - 36 | Payload | 32 bytes max |
-| payload length + 4 | CRC | XOR of all previous bytes |
