i do some test today: With ublox LEA debug return "DEBUG 9,6,5,0,4,1,1,2,1,1,1,1,1,1,1 ..." With ublox neo6 debug return "DEBUG 0,0,0,0,0,0,0,0,0,0,0,0,0,0" i think the problem is the ACK NACK response. i will search the problem tomorrow. now is 6:12pm ... i need sleep.

I mean configuring the noe-6 family though the gps_ubx_ucenter module on LPC2148 family autopilot ? thanks ! Imed LIMAIEM address@hidden

I would very much appreciate that
David.
For the TWOG I have tried the twinjet.xml airframe
file from the examples folder and added the gps_ubx_ucenter module and
configured GPS_LED and SYS_TIME_LED.
For Umarim I have tried the umarim_lite_v2.xml
airframe file and added the gps_ubx_ucenter module.
Cheers
Jeremy

I have one of those GPS and a UmarimLite + TWOG. I can
test. Regards,

Very weird. We had a MAX5 connected to a TWOG before.
Can you look at the telemetry. The ucenter module reports some
data in the debug message on startup. The baud rate it found the GPS reply,
the firmware and hardware versions etc. Do you receive that message?
If possible, next would be looking at the rx and tx with the
scope. Is anything being sent to your gps?
Can you pastebin your airframe files?
There should be no reason for twog and umarin to behave
differently here...

Thanks
Christophe,
Working through your suggestions
as follows:
1) Rx-Tx pins swapped = definitely
not
2) Uart0 <-> Uart1 swapped = I am using the
default "DownLoad GPS" Uart0 connector on the TWOG.
3) Non correct voltage supply to GPS (5v gps or 3.3v ?) = this GPS module has a 3.3V regulator and I am powering
with 5V from the TWOG and Umarim.
4) ROTORCRAFT <-> FIXEDWING firmware (configures rate of
NAV_SOL to 1Hz on fixedwing that use LLH for position and 4Hz for
rotorcraft with ECEF->LTP position)= definitely
fixedwing in aircraft file.
5) most UBlox have 2 or more ttl ports, a usb port and even an i2c
port. Depending on the GPS board it can be ublox_port1 or ublox_port2 that
is routed to the pins (not to confuse with paparazzi_lpc_port0 and port1)
The ubx_module can configure the GPS to give its messages on another port
with the GPS_PORT_ID
define. If not provided, the module assumes GPS_PORT_UART1.
But you can define more options: https://github.com/paparazzi/paparazzi/blob/v4.0/sw/airborne/modules/gps/gps_ubx_ucenter.c
LINE 267 -> = the MAX-6Q has a single ttl port which
is GPS_PORT_UART1 (the default).6) Other airframe file related problem: e.g. trying to run umarin
itg3200 imu code in a twog that has not have it... (imu does stops the
boot if not configured correctly)= airframe files are
identical other then their board and IMU settings.
I have a Paparazzi GPS and CSGShop GPS for
testing and I can connect either to the Umarim and both
will work. The Paparazzi GPS (LEA-5H) works on the TWOG but the CSGShop
(MAX-6Q) GPS refuses to work on the TWOG. Of course the Paparazzi GPS does
not need the gps_ubx_ucenter module and this is why I am suspecting a
software error.
Also worth noting that I can fit a backup battery
to this GPS module and configure it via ucenter and it will work on
the TWOG. But the MAX-6Q will return to its default settings when the
battery is removed or goes flat. So I am trying to get it to work
without the backup battery.
Has anyone else tried a TWOG and CSGShop (MAX-6Q)
GPS?
Cheers
Jeremy

and gps_ubx_ucenter module
Dear Jeremy,
The gps_ubx_ucenter module does exactly the same on all LPC21
variants of autopilots, actually even on the STM32's. The only possible
differences can be:
1) Rx-Tx pins swapped
2) Uart0 <-> Uart1 swapped
3) Non correct voltage supply to GPS (5v gps or 3.3v ?)
4) ROTORCRAFT <-> FIXEDWING firmware (configures rate of
NAV_SOL to 1Hz on fixedwing that use LLH for position and 4Hz for
rotorcraft with ECEF->LTP position)
5) most UBlox have 2 or more ttl ports, a usb port and even an i2c
