alternative deamon for lapisrv for external gps receivers?!?

[vanrent]

Dear Mightymop,
I compared/adapted your script and ran it step by step...
My bt connection is ok:
./sbin/hciconfig hci0
hci0: Type: UART
BD Address: 00:15:A8:01:4F:14 ACL MTU: 377:10 SCO MTU: 64:0

TX bytes:34 acl:0 sco:0 commands:7 errors:0
rfcomm
rfcomm0: 00:02:76:FD:53:AF channel 1 clean
Then I start your gpsd daemon:
./gpsd

GPSd Process-ID: 756

Problems with pipe on connecting to /tmp/rfcomm0
Handshake-Thread (ID: 418999829528576) ends...
Errow in Handshake-Thread...

It's very slow and after 3 "Error in Handshake-Thread", I receive a
"No GPS signal" on the A780

Any idea?
Thanks,
Bernard

hmm sounds bad

what does a "cat < /tmp/rfcomm0" shows you? there should come nmea data from the bluetooth bt receiver after you started the bt-script

Thanks mightymop!
I could also get GPS data from external GPS to copilot working.

Any idea how to get data back to lapisrv? Basically I want the data to be available to j2me apps thru location APIs (JSR179)...

hy all,

i have the following problem:
my internal gps receiver is no longer working (probably the flex-cable is broken - i tried a lot of solutions to bring back the internal gps, no one ruled) so i decided to buy a new bt gps receiver (took a qstarz bt-q81 and installed the soft stuff listed in this thread to bring copilot back work with my new bt gps receiver.

here is my configuration:

hw:
- a780
- bt-q818 (gps receiver)
sw:
- bluez-02
- gpsd_187.cpp (i created also gpsd.conf, with this content: interface=/tmp/rfcomm0 , in same directory where gpsd is)

starting things this way (in ekonsole):

export PATH=$PATH:/diska/bluez/bin:/diska/bluez/sbin:/diska/bluez
export LD_LIBRARY_PATH=/diska/bluez/lib

cd /diska/bluez
cd btmod/
insmod bluez.o
insmod sco.o
insmod l2cap.o
insmod rfcomm.o
insmod bnep.o
insmod hidp.o
insmod hci_uart.o
cd ..

./bton
/usr/SYSbt/dload /dev/ttyS1 1 460800 $MAC_OF_BT-CHIP 0
./ezx-hciattach -d
/diska/bluez/etc/init.d/bluetooth start
if ! test -e /tmp/rfcomm0; then mknod /tmp/rfcomm0 c 216 0; fi

sleep 2;
/diska/bluez/sbin/hciconfig hci0 up
sleep 1;
/diska/bluez/bin/hcitool -i hci0 cc $MAC_OF_GPS_RECEIVER
sleep 1;
/diska/bluez/bin/rfcomm bind /tmp/rfcomm0 $MAC_OF_GPS_RECEIVER
sleep 1;

and in an new shell:

cd /diska/gpsd
./gpsd &

at this moment in /tmp/rfcomm0 is the following:

cat /tmp/rfcomm0

and get:

$GPGGA, 200634, 000, A, 4645, 0348, N, 0053, 3, 3413, E, 0, 11, 326, 44, 10634,,,A*59

$GPRMC, , 200634, 000, A, 4645, 0349, N, 0053, 3, 3413, E, 0, 2, 14, 22, 556,,,A*51

...and so on

i fire up copilot from gui

and now gpsd output is as follows:

and so on...

after 10 minutes copilot still didn't has determined the current position...still showing: determining current position...from my point of view things are looking good...hmmm...

at least gpsd is still runing and produces the above output

so if anyone knows how to fix it, plz tell me.

thx a lot in advance and also for the great work!

[mightymop]

hmm sounds like a strange bug...

try the binary in the attachemend plz...
(rename gpsd.zip to gpsd)

by the way: delete the /tmp/lapisock file ... and kill lapisrv deamon first ^^ before running gpsd

greetz mightymop

[phillo]

thx a lot mightymop - that s real mighty

i did what you suggested and now copilot is working again, yeaaah

cheers

[mightymop]

for all visitors plz have a look on the first post in this thread...
