[gpsd-users] gpsd exits on nmea-sentence with bad syntax

[Victor Klein]

Hi,

I found that gpsd exits without notice if if gets a sentence with a not 
wellformed syntax.

example: $IIVHW,,T,052,M,000.0,N,000.0,$*62, the $ sign is the problem, 
the correct sentence is
                 $IIVHW,,T,052,M,000.0,N,000.0,K*62

if there is another fault in the sentence , the gpsd produces rubish like:

$IIVHW,,T,053,MH000.0,N,000.0,K*63  --> 
2449495648572c2c542c3035332c4d483030302e302c4e2c3030302e302c4b2a36330d0a
$IIVHW,,T,054,M,000.0,N,00010,K*64   --> 
2449495648572c2c542c3035342c4d2c3030302e302c4e2c30303031302c4b2a36340d0a
$IIVHW,,T,054,M,000.0,N,000.00K*64   --> 
2449495648572c2c542c3035342c4d2c3030302e302c4e2c3030302e30304b2a36340d0a
$IIMTW,020.4IC*25   -->   2449494d54572c3032302e3449432a32350d0a



I'm using gpsd on a TP-Link MR3020 with openwrt. The supported version 
is 3.7.
I read the data from a Seatalk-to-NMEA-USB-Converter, which produces 
randomly some bad sentences.


Help appreciated.
