MC60CB GPS Jamming Detection

IoT Modules GSM Module
1

Hello,
I have MC60CB module. I want to Detect to GPS Jamming.
I wrote the code in MC60CA, it runs, but the code I wrote doesn’t run in MC60CB, where is the problem?

ret=Ql_RIL_SendATCmd(“AT+QGNSSCMD=0,"$PQJAM,W,1,1*3C"”,31,NULL,NULL,0);

ret=Ql_RIL_SendATCmd(“AT+QGNSSRD?”,11,ATResponse_Handler,NULL,3000);

In the output of … “$PMTKSPF,1” … command, is not shown.

thank you

There is a key problem. Do you burn the sdk of MC60CA on the MC60CB module? The PA of the module of MC60CA is different from that of MC60CB, which will affect the antenna and thus the gnss signal. If it is just the sdk, it can be universal, but the core part of the firmware can not pass, make sure that your MC60CB module is using the MC60CB firmware

Thank you for your reply

I changed the firmware of the device to MC60CAR01A15.

Is it possible for me to download the MC60CB firmware or email it to me? tarait53@gmail.com

thanks

I did the update operation. But the problem was not solved.
These are the commands I write and the output I get is written below.
My problem is that I can’t get the GPS jamming status output.

ret=Ql_RIL_SendATCmd(“AT+QGNSSC=1”,11,NULL,NULL,0);
ret=Ql_RIL_SendATCmd(“AT+QGNSSCMD=0,“$PQJAM,W,1,1*3C””,31,NULL,NULL,0);
ret=Ql_RIL_SendATCmd(“AT+QGNSSRD?”,11,ATResponse_Handler,NULL,3000);

Output:
+QGNSSRD: $GNRMC,000449.869,V,0.00,0.00,060180,N52
$GNVTG,0.00,T,M,0.00,N,0.00,K,N2C
$GNGGA,000449.869,0,0,M,M,58
$GPGSA,A,1,1E
$GLGSA,A,1,02
$GPGSV,1,1,0079
$GLGSV,1,1,0065
$GNGLL,000449.869,V,N6A

And I can’t see this statement in the output:

$PMTKSPF,1 // 1 No jamming, healthy
OR
$PMTKSPF,2 // 2 Warning status
OR
$PMTKSPF,3 // 3 Critical status
