About AFC command

[Thomas_Ji]

Hi 

We want to run the AT command as the following, the response is always ERROR.

signal generator: CW,  freq=param1-120KHz=1804.88MHz,   power: -100dbm

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

and Run the GPS SNR command AT%XRFTEST=2,1,-84,0, the response is OK.

signal generator: CW,  freq=param2+330KHz=1575.75MHz,  power: -100dbm

What is the reason?

Best Regards

Thomas

How about the version of the modem?

Mfw v1.3.1.

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
