Error on BRKWS20 #6

Closed crazyday closed 4 years ago

crazyday commented 4 years ago

I'm testing BRKWS20 board that contains the SFM20R1 microcontroller with the demoapp.

The result is an error on GPS : 14 GPS Acqusition Stop. C/N0 Low! Time Out(10 sec)! C/N0[0]dB-Hz

Does anyone have a solution ?

Thanks

I have the same issue. In the last version of the sdk the time out was set to 60 secs, it maybe that but i'm not sure and i haven't try yet

GPS_OPERATION_MODE_DEFAULT to 1 (CGPS_MANUAL_MODE) change CDEV_FS_VER or use factory_write (development\SFM\binary\development\SFM\binary) Use GPS antennas with active antennas.

crazyday commented 4 years ago

your answer is incomprehensible. Change CDEV_FS_VER by what ?

Your SFM20R1 module is poorly documented. Your SDK doesn't work. I don't understand that Sigfox refers you.

Why closing the issue, it's not resolved ?

yepark-wisol commented 4 years ago

It is about the initial default value of the setting value for GPS operation. The setting will be retained and will be initialized when the FS version changes or Erases. Change the default value of GPS_OPERATION_MODE_DEFAULT to change the define value. After that, run "download_Factory.cmd" or change "CDEV_FS_VER" to apply it. CDEV_FS_VER is the version value of the setting area.

This solution is not working 14 GPS Position Not Fixed! tracking_time[75]sec C/N0[0]dB-Hz

Yohannfra commented 4 years ago

We should not have to ask those questions, this should be documented..

crazyday commented 4 years ago

Ca je suis bien d'accord. Travailles-tu sur la BRKWS20 ?

Yohannfra commented 4 years ago

Oui, je peux avoir ton mail ou quelque chose pour te contacter ?

Please check the GPS antenna.

Yohannfra commented 4 years ago

@yepark-wisol the GPS antenna is fine, it's not about it. I tried your solution and i still have the same error : 

...
00> 02 GPS Start

00> 14 GPS Position Not Fixed! tracking_time[90]sec C/N0[25]dB-Hz 
...

Something is clearly not working. Would a full log of the demoMain help you to help us ?

Thanks.

yepark-wisol commented 4 years ago

The GPS ran for 90 seconds but failed to position fix. Check the antenna. This cannot be helped by software.

yepark-wisol commented 4 years ago

Is it correct to use an active antenna? Did you test it on the out door?

crazyday commented 4 years ago

Yes, in the BRKWS, it's an active antenna. I tested with another active antenna, the result is the same. I test both indoor and outdoor.

Either the gps module of the controller wssfm20r1 does not work, or it comes from the code.

Strangely, the result is the same on version 12 of the SDK.

Yohannfra commented 4 years ago

I just tried the gps outdoor and it works thanks @yepark-wisol . That's still strange that it does not fix when i'm indoor but it's not software anyway.
