Re: [Paparazzi-devel] GPS receiver GS407

[Prof. Dr.-Ing. Heinrich Warmers]

Hi Rolf,
is it a battery, akku or a super cab ?
In the past i found that i had to power on the GPS modules  about 4 times a year for more than an hour.
The old SAM LS module has a battery. For proper  function i had to connect the battery connectors pins
to make the GPS working with no battery.
If the voltage of the battery is to low the module fails totally.

Hi

My 407 arrived and shows the same behaviour: connects fine with ucenter, doesn't keep changes.
I tried to connect an additional backup-battery which helps to keep the settings but this is not my prefered solution for this issue.

I have this GPS which has a uBlox6 chip and it shows very similar
behavior.

No problem to connect to it via ucenter, but it doesn't keep the changes
after a powercycle.

sounds promising :-) 

I had the gps connected to u-center via the serial port (ftdi board) and
      

full acces. 
    

The default baudrate that is restored after disconnecting the power is
      

9600. connected the GPS to the autopilot (twog) gives the mentioned debug
message. looking through the code I dont see an option where a random
hardware or software version is crated - so I m pretty sure that part is already
working. 
    

Would be really nice if you could lend me a hand to fix this ...
