Send Raw Message (serial message type 0x27)

The SmartOne will send raw user data using the Raw Payload command 0x27.
53 bytes plus 6 bits of user data may be sent. Two bits are set in the on-air message by the SmartOne
informing the recipient that the message is Raw.
The following table defines the message structure used to send a Raw message.

Example 1 - Sending a Raw User Message:
The Host sends:
AA 0E 27 10 22 33 44 55 66 77 88 99 <CRC-low> <CRC-high>
The SmartOne Responds:
AA 05 27 <CRC-low> <CRC-high>
What actually goes out over the air is:
12 22 33 44 55 66 77 88 99
The least two significant bits of the first byte are always "10" for a raw message (a HEX or

decimal value of "2", the remaining 6 bits make up the top 6 bits of the first byte sent in
the serial command, in this example 000100xx (with the "xx" representing the two bits that
the SmartOne forces to "10").
