[gpsd-dev] RTCM relaying problem

[José Miguel Gonçalves]

Working with a RTCM caster I've noticed that not all RTCM packets that 
gpsd received were relayed to my GPS receiver, what caused DGPS 
corrections to be intermittently applied or not applied at all. To fix 
this I needed to apply the following patch to avoid RTCM packet 
overlapping:


diff --git a/gpsd.c b/gpsd.c
index d8f229b..abdaca1 100644
--- a/gpsd.c
+++ b/gpsd.c
@@ -1422,7 +1422,7 @@ static void consume_packets(struct gps_device_t 
*device)
     }
 #endif /* NETFEED_ENABLE */

-    for (fragments = 0; ; fragments++) {
+    for (fragments = 0; (changed & (RTCM2_SET | RTCM3_SET)) == 0; 
fragments++) {
        changed = gpsd_poll(device);

        if (changed == ERROR_SET) {
