Example:
radio tx 48656c6C6F
// Transmits a packet of
[0x48][0x65][0x6c][0x6C][0x6F]
;
Hello
.
2.5.3
radio cw <state>
<state>
: string representing the state of the Continuous Wave (CW) mode, either
on
or
off
.
Response:
ok
if state is valid
invalid_param
if state is not valid
This command will enable or disable the CW mode on the module. CW mode allows
the user to put the transceiver into Transmission mode to observe the generated signal.
By altering the settings for the radio the user can observe the changes in transmissions
levels.
Example:
radio cw on
2.5.4
rxstop
Response:
ok
This command causes the radio to exit Continuous Receive mode initiated through the
radio rxstop
command.
Example:
radio rxstop
Note:
In order to meet ETSI regulations in the given frequency bands, the radio
has to use either Listen Before Talk (LBT) + Adaptive Frequency Agility
(AFA) or duty cycle limitations. By issuing the
radio tx <data>
command the module does not perform LBT before transmission, thus the
user has to make sure that duty cycle limits are not violated. For more
information on duty cycle limits please check the EN 300 220-2 v2.4.1
standard.
Note:
The
mac pause
command must be called before any radio transmission
or reception, even if no MAC operations have been initiated before.
Note:
When transmitting FSK packets, the payload and the 2-byte CRC is
whitened by being XORed with a pseudorandom sequence generated by
an LFSR with the polynomial X
9
+ X
5
+ 1. This process is automatically
reverted on reception so that it is transparent to the user.
Note:
Please note that using
radio cw off
resets the module, this command
being semantically identical to
sys reset
.
