Read Radio Frame 3

Returns the next radio frame from the buffer of the MBWBLUE, if there is any. This version of the radio
frame read command returns a maximum of 256 bytes of data (all bytes hexadecimal). If you are only
using MBWBLUE with firmware version 3.00 and up it is advised to use this command instead of Read
Radio Frame 2. However, if you want a command which works with all versions of the MBWBLUE use
Read Radio Frame 2.
NOTE: This command is only available with firmware version 3.00 and up.
NOTE: The length byte contains only the LSB of the real length (0x128) of this command.

The format of [Frame data] is:
[Radio Frame]
RSSI
Time type
Radio mode
Unused 1
Unused 2
Timestamp
Unused 3
Good frames T
Good frames CA
Good frames CB
3 of 6 errors
CRC errors

01 FE 06 40 CRC CRC
01 FE 28 40 00 [Frame data] CRC CRC
01 FE 28 40 FF [289 arbitrary bytes] CRC CRC
256 bytes containing the radio frame and at the end arbitrary fill bytes.
The first byte of the radio frame contains the length.
If there is no received radio frame available from the buffer of the MBWBLUE
(no reception), the length byte is zero and the radio frame, RSSI, radio mode
and timestamp are invalid. However, the statistics values (good frames T, CA,
CB and so on) are valid.
1 byte containing the received signal strength indicator 0%...100%. To get the
RSSI in dBm:
(RSSI -120) dBm
1 byte containing zero (0)
1 byte: 0x00 = 868 MHz T1
0x01 = 868 MHz C1A
0x02 = 868 MHz C1B
0x03 = 868 MHz S1
0x04 = 868 MHz C2A
0x05 = 868 MHz C2B
0x10 = 434 MHz T1
0x11 = 434 MHz C1A
0x12 = 434 MHz C1B
0x13 = 434 MHz S1
0x14 = 434 MHz C2A
0x15 = 434 MHz C2B
0xFF = unknown
NOTE: The radio mode is only available with firmware version 3.42 and
up. This byte is invalid (0xFF) for previous firmware versions.
1 byte unused (0xFF)
1 byte unused (0xFF)
4 bytes containing the seconds from starting the MBWBLUE to reception of
the radio frame (LSB first).
4 bytes unused (0xFFFFFFFF)
4 bytes (LSB first) containing the number of correctly received mode T frames
4 bytes (LSB first) containing the number of correctly received mode C frames
(format A)
4 bytes (LSB first) containing the number of correctly received mode C frames
(format B)
4 bytes (LSB first) containing the number of received frames with 3 of 6 errors
4 bytes (LSB first) containing the number of received frames with CRC errors
