DataField
DataField
:
PMTK223,SV,SNR,Extension threshold, Extension gap
SV: it means the module need extend the time to receive more ephemeris data while the number of
satellite without ephemeris data.
SNR: it means the module needs to enable the ephemeris data receiving while the SNR of satellite is
more than the setting value.
Extension threshold (millisecond): extension time for ephemeris data receiving
Extension (millisecond): gap time between EPE data receiving
Example
SV: it means the module need extend the time to receive more ephemeris data while the number of
satellite without ephemeris data.
SNR: it means the module needs to enable the ephemeris data receiving while the SNR of satellite is
more than the setting value.
Extension threshold (millisecond): extension time for ephemeris data receiving
Extension (millisecond): gap time between EPE data receiving
Example
:
$PMTK223,1,30,180000,60000*16<CR><LF>
