Hi,

[quote user="Thomas_Ji"]How about the version of the modem?[/quote]

Mfw v1.3.1.

[quote user="Thomas_Ji"]

Do you have any suggestion about this question? or do you have any action before the command from power on the DK?

Could you please supply you hex file and list the action step by step.

It is unmodified SLM and at_client that I tested with, running on a nRF9160DK v1.0.0.

No changes at all to the source files, just booted and issued the AT command that you mentioned (AT%XRFTEST=4,1,3,18050,-100).

Did you try this with the at_client sample?

Kind regards,

Håkon

It is stock SLM, no changes. Tested both ncs v1.8.0 and v1.9.0.

Kind regards,

Could you supply your SLM application hex file, and we can test in the DK.

Best Regards

Hi Thomas,

I tested this on my end on two projects, both successful.

Sample output from at_client:

*** Booting Zephyr OS build v2.7.99-ncs1-rc1  ***
The AT host sample started
AT%XRFTEST=4,1,3,18050,-100
%XRFTEST: 8005,4761
OK

Sample output from SLM:

Ready
AT%XRFTEST=4,1,3,18050,-100

%XRFTEST: 8099,4817
OK

Kind regards,

Håkon

I run the AT+CFUN=4 or AT+CFUN=0 first, the response is OK, and than run the AFC command, the response is ERROR also.

Best Regards

Thomas

Hi,

When issuing XRFTEST AT commands, are you certain that the modem is off or in flight mode (AT+CFUN=4 or CFUN=0)?

Kind regards,

Håkon
