Radio Set Commands
2.5.5.1
radio set afcbw <autoFreqBand>
<autoFreqBand>
: float representing the automatic frequency correction, in kHz.
Parameter values can be: 250, 125, 62.5, 31.3, 15.6, 7.8, 3.9, 200,
100, 50, 25, 12.5, 6.3, 3.1, 166.7, 83.3, 41.7, 20.8, 10.4, 5.2, 2.6.
Response:
ok
if the automatic frequency correction is valid
invalid_param
if the automatic frequency correction is not valid
This command modifies the automatic frequency correction bandwidth for
receiving/transmitting.
Example:
radio set afcbw 125
2.5.5.2
radio set bitrate <fskBitRate>
<fskBitRate>
: decimal number representing the FSK bit rate value, from 1 to
300000.
Response:
ok
if the bit rate value is valid
invalid_param
if the bit rate value is not valid
This command sets the FSK bit rate value.
Example:
radio set bitrate 5000
// FSK bit rate is set to 5 kb/s.
2.5.5.3
radio set bt <gfBT>
<gfBT>
: string representing the Gaussian baseband data shaping, enabling GFSK
modulation. Parameter values can be:
none
,
1.0
,
0.5
,
0.3
.
Response:
ok
if the data shaping is valid
invalid_param
if the data shaping is not valid
This command modifies the data shaping applied to FSK transmissions. Entering any
<gfBT>
other than
none
will result in a Gaussian Filter BT being applied to
transmissions in FSK mode.
Example:
radio set bt none
// Data shaping in FSK mode is disabled or null.
