Third Party FOTA Fails

IoT Modules RC76
1

I am attempting to the the Third Party FOTA feature via AT+WDSTPF

In a network trace I see the module attempt to connect to a test HTTP server we setup for this however it then immediately stops downloading.

Via WDSI we see the following updates

WDSI = 9
WDSI = 18
WDSI = 11

Which seems to suggest and issue with the Flash but I have tried on multiple modules and they all show the same behavior so actuly HW issue in flash seems unlikely. Note, update via AirVantage does work.

  • Does anyone have Third Party FOTA command working? How should this work?
  • What file should be hosted on the http server? Right now I have and SPK file on there but there are not docs about this so this is an assumption.

which module are you using?
RC76?
how do you configure AT+WDSTPF?

Below is an example for RC7620:


 AT+WDSC?
 
 
 +WDSC: 0,0
 +WDSC: 1,0
 +WDSC: 2,0
 +WDSC: 3,0
 +WDSC: 4,15,60,240,480,1440,2880
 +WDSC: 5,0
 +WDSC: 6,0
 
 OK
 AT+WDSG
 
 
 +WDSG: 0,2
 +WDSG: 1,0
 
 OK
 AT+WDSTPF?
 
 
 +WDSTPF: 0,"https://123.123.123.123/s/xxx"
 +WDSTPF: 1,0
 
 OK
 AT+WDSTPF=0,"https://123.123.123.123/s/xxx"
 
 OK
 AT+WDSTPF?
 
 
 +WDSTPF: 0,"https://123.123.123.123/s/xxx"
 +WDSTPF: 1,0
 
 OK
  AT+WDSTPF=1
 
 OK
 
 
 +WDSI: 4
 
 
 
 +WDSI: 8
 
 
 
 +WDSI: 9,35097848
 
 
 
 +WDSI: 18
 
 
 
 +WDSI: 18,1
 
 
 
 +WDSI: 18,2

Thanks for your reply.

The module is an RC7620-1

Model: RC7620-1
QTI baseline: MPSS.JO.2.0.2.c1.1-00073-9607_GENNS_PACK-1.363371.1.378695.1
Revision: SWI9X07H_00.08.07.00 0ce4c1 jenkins 2021/03/17 02:18:20
IMEI: 351080657527245
IMEI SV: 17
FSN: 7T2513303702B1
+GCAP: +CGSM,+DS,+ES

I have a bit more info the WDSI status is +WDSI: 11, 2 which suggests something wrong with the SPK file.

Right now I am using the SPK file from

https://source.sierrawireless.com/resources/airprime/software/rc76xx/rc76xx-firmware-release-10,-d-,0/#sthash.7Tnnw6va.dpbs

so I assume that should be correct.

The only difference that I see w.r.t. to your example is that WDSG give me

+WDSG: 0,3
+WDSG: 1,2

as I have also tried this unit on AirVantage and I do not know how to reset that back to its original state.

Currently I can also see “+WDSI:11,2” in FW R10.
I will update later.

For the package used in the third party FOTA, it is not using the spk file, it’s another kind of the FOTA package.
Please contact distributor to get the file.
