4.2.2.2 Command mode

As described above, in command mode hexadecimal commands are used to control the radio
module. Both, the sub-GHz proprietary module and the Thyone-I, use a similar command
structure, whereas the Thyone-I uses a 2-byte length field and the sub-GHz proprietary mod-
ule uses a 1-byte length field:
Start signal
0x02
Start signal
0x02
Table 5: Command structure of the sub-GHz proprietary module
Furthermore, the commands themselves differ. See the CMD_DATA_IND command for example,
that outputs the radio data on the UART:
Start signal Command
0x02
Start signal
0x02
Table 7: CMD_DATA_IND command of the sub-GHz proprietary module
Besides the length of the Length field as already described, the Command byte itself ( 0x81 vs.
0x84 ) as well as the location of the remaining fields changed.
As consequence of this all commands must be updated to the new commands.
Please note that the Wireless Connectivity SDK [1, 2] implements all these
commands. Thus, only the driver of the sub-GHz proprietary module must be
replaced by the Thyone-I driver to update the application to the new commands.

4.2.3 Radio interface

4.2.3.1 Network and mesh

Both, the sub-GHz proprietary module and Thyone-I, provide several network topologies.
Data can be transmitted from point to point (unicast), point to a sub net (multicast) or point to
