nRF9151 supported AT commands

[Jamal_nRF]

Dear Customer Support,

We are gathering the list of supported AT commands support for the nRF9151

Also experimenting available AT commands using the nRF9151DK

So far, we have found two documents:

nRF91 AT Commands - Command Reference Guide v0.7

nRF91x1 Cellular AT Commands - Command reference Guide v1.3

Could you please confirm we are using the latest version for these pdf documents?

Also please let us know if we are missing other AT command documents relevant to the nRF9151

Thank you

Jamal

PS

couple AT command examples we could not find are ATE0 and ATV0

are these no longer supported on the nRF9151?

Hi Jamal,
Could you tell me more about what you are trying to achieve here? AT%XRFTEST is available in regular MFW.

1. You can use the AT client to issue AT commands to the modem.
2. No, the modem FW is closed source.
3. I am not quite sure what you mean here. Do you mean to issue the command from the application?
4. I will come back to you on this, I think it is shipped with the PTI but I will double check.

[Benjamin]

Yes, the nRF9151 comes with the PTI.

Hi Benjamin,

Thank you for confirming the nRF951 is shipped with the PTI image by default

Re: what are you trying to achieve?

For factory support, there is a request for a specific AT command to control TX mode --which seems to be fulfilled by at%XRFTEST

Yes, I have been able to confirm it is available in regular MFW 2.0.2

Also been able to test it with the ModemShell application available from the Desktop / Quick Start

Realized I had to turn off modem first through cfun=0

> at+cfun=0
at+cfun=0
+CGEV: ME DETACH
OK
> at%xrftest=0,0
at%xrftest=0,0
OK
> AT%XRFTEST=0,1,1,21400,-65,0
AT%XRFTEST=0,1,1,21400,-65,0
%XRFTEST: -26428,-54
OK
> at+cgmr
at+cgmr
mfw_nrf91x1_2.0.2
OK

>>> So I don't think any further integration work is needed to support this test command

Thank you

Hi Benjamin,

Follow up question regarding the %XRFTEST command

--as documented in section 11. Production test commands

of the "nRF91x1 Cellular AT Commands" manual, page 201.

As stated, the proprietary %XRFTEST command can be used to test the nRF91x1 receiver.

Is there a command specific for testing the RF transmitter for the nRF9151?

What alternative is available to test the RF transmitter in FTM (Factory Test Mode)?

Best regards,

[Jamal_nRF]

More information:

The %XRFTEST command is also documented in this PTI document:

https://docs.nordicsemi.com/bundle/ref_at_commands_pti/page/REF/at_commands/intro_pti.html

Section 4.24 TX test %XRFTEST on page 38

where there is more details about the TX test using the same command.

Question:

Does the TX test require the PTI firmware to be programmed on the modem core?

Please confirm...

Jamal

PS

Looking back at my earlier note from last month, I was able to execute the XRFTEST command for the receiver --setting <test> parameter  to 0.

But for transmitter, the <test> parameter needs to be set to 1.

Which does not seem to work using modem firmware version mfw_nrf91x1_2.0.2

AT%XRFTEST=1,1,12,7040,20,1

ERROR
AT%XRFTEST=1,0

ERROR

The TX test requires the PTI firmware running on the modem core. With the Cellular modem firmware, only the RX test is available.

Appreciate the confirmation, thank you
