7.2 Data transfer and reception in the command mode

This group of commands include the commands that either are used to request a radio

telegram to be send or indicates a received frame.

7.2.1 CMD_DATA_REQ

This command serves the simple data transfer in the command mode. Transmission takes

place on the conﬁgured channel to the previously parametrised destination address (taken

from the volatile RuntimeSettings). This command is especially suitable for transmission for

a point-to-point connection. The maximum number of payload data Bytes depends on the

chosen

RADIO_DefaultRfProfile

Format:

Start signal Command Length Payload CS

0x02 0x00 1 Byte Length Bytes 1 Byte

Response (

CMD_DATA_CNF

Start signal Command | 0x40 Length Status CS

0x02 0x40 0x01 1 Byte 1 Byte

Status:

0x00: ACK received or not requested (

MAC_NumRetrys

is 0,

MAC_DefaultAddressMode

is 0

or a broadcast address is set as destination address)

0x01: no ACK received within a time-out after using all

MAC_NumRetrys

0xFF: invalid (payload too long)

7.2.2 CMD_DATAEX_REQ

This command serves data transfer in a network with several parties. Both the RF channel

to use and the destination address (depending on the parametrised address mode) are

speciﬁed along with the command. The maximum number of payload data Bytes depends

on the chosen

RADIO_DefaultRfProfile

. The entered channel, destination network and

destination address are loaded into the volatile RuntimeSettings and thus are kept until the

system is reset or these values are modiﬁed again.

Please note that the format of this command depends on the conﬁgured

MAC_DefaultAddressMode

Address mode 0:
