Sodaq One (RN2903) fails to join network

cam · April 26, 2017, 12:29am

Hi all,

I have a sodaq one rev 4 and I would like to use the supplied code:

I have used the serial passthough code and I’m able to send messages successfully. However using the above sample code I have not been able to join.

I have enabled the further debugging and both fail for different reasons, ultimately I would like to use the tracker so I will upload the log for it:

It looks as if the setting were configured correctly but that there was an error while transmitting.

I hope someone can help with my problem, any help is greatly appreciated.

Dear Cam,

What is the board file version you use?

Jan

Hi Jan,

I have just changed to 1.6.14 however I was using 1.6.12. PS I have a Sodaq One rev 4 and using the SodaqOne Universal Tracker - 3.0.
With the new board version, the RN module is no longer seen:

As mentioned earlier, I can use the module fine using the pass through code.
Any help you can provide in order to get a resolve for this problem is greatly appreciated.

Hi Cam,

I was able to reproduce the issue.
Arduino made some changes, we have updated our RN2483 library (also for RN2903).
We didn’t update this yet in the Tracker V1 software.

Download tracker V2 software and copy the two RN2483 files into the V1 tracker software.
Please let me know if this solves your issue.

I’ll update our github soon.

Regards,
Jan

Hi Jan,

Thanks for the huge help. I have replaced the header and cpp files and my problem has been resolved with the caveat that I also changed the default FSB to that I was using. I think this will be particularly useful to others using the Sodaq One in Australia.

Cheers
Cam

PS I will now try to have the GPS fix < 1 minute

Jan · May 3, 2017, 11:23am

Hi Cam,

Please share the code for the default Australian FSB settings.
I can build them in the V1, V2 of the tracker software.

Regards,
Jan

cam · May 3, 2017, 11:31am

Hi Jan,

By default, in the RN2483 header file the FSB was set to 2. With a gateway using only the first 8 channels (0 thru 7 - in Aus 915.2MHz thru 916.6MHz), I needed to set the FSB to 1. Please see here:
http://www.microchip.com/forums/m926581.aspx

I think that it would be a good idea to include the FSB option in the settings menu for future revisions.

Cheers
Cam

PS I am also using the RN2903AU 0.9.7rc7 firmware.

Hi Jan,

I have noticed a problem with the setting of the SF, I have successfully transmitted data using SF7 and SF9 however it fails when using SF10:

As can be seen in the dump, after changing the SF from 9 to 10 the device fails to join. Is there a fix for this problem.

Hi,

Whats the time between the messages?
If you send too many packages its maybe the duty cycle.

Can you at least wait 2 minutes between each packet?

Regards,
Jan

cam · May 4, 2017, 10:57am

Hi Jan,

Seems to occur regardless of time, I have set to fix to 60 min and have to same error.

Cheers
Cam
