Hello!

[quote userid="111786" url="~/f/nordic-q-a/121315/possible-bug-cellular-modem-sample-with-nrf9151-running-slm/535908"]Can you try to set configuration options shown below in SLM and cellular modem samples?[/quote]

Thank you for your answer, looks like those configuration options solved it!

CONFIG_MODEM_CMUX_MTU=127
CONFIG_MODEM_CMUX_WORK_BUFFER_SIZE=134

Thank you so much, would be nice to mention it somewhere in the sample for future in case someone else encounters this issue also.

Hi,

Can you try to set configuration options shown below in SLM and cellular modem samples?

CONFIG_MODEM_CMUX_MTU=127
CONFIG_MODEM_CMUX_WORK_BUFFER_SIZE=134

Hi,

Thank you for the update. We will look into this internally. I expect to get back to you by the end of the week.

I would like to provide an update, which seems to give chance to the application to fetch the values from time to time.

I changed the following code in zephyr modem_cellular.c file.

https://github.com/nrfconnect/sdk-zephyr/blob/v4.0.99-ncs1-branch/drivers/modem/modem_cellular.c#L1521-L1523

MODEM_CHAT_SCRIPT_CMDS_DEFINE(get_signal_cesq_chat_script_cmds,
                  MODEM_CHAT_SCRIPT_CMD_RESP("AT+CESQ", cesq_match),
                  MODEM_CHAT_SCRIPT_CMD_RESP("", ok_match));

into

MODEM_CHAT_SCRIPT_CMDS_DEFINE(get_signal_cesq_chat_script_cmds,
                  MODEM_CHAT_SCRIPT_CMD_RESP("AT+CESQ", cesq_match));

After doing this change, the application is able to return SUCCESS on cellular_get_signal() and fetch the values of RSRP and RSRQ correctly. I don't think that this is the solution because the function still returns errors from time to time not being able to fetch the values. However, this could be a clue for the engineering team.

Hello,

Sorry for delay in reply as it was the weekend.

Please find the screenshots from debugging session in VScode.

Hi,

Thank you for clarification.

Can you show errors (possibly as a screenshot) that you see in your debug session?

I am sorry if I didn't make it clear but the problem is that I am unable to retrieve RSRQ and RSRP values from the modem using cellular_get_signal() function. This function returns either -16 or -22 it is not consistent in returning one error code or other constantly, I am seeing this when I set breakpoints after the return of the function during debugging session. If you see the cellular sample there is only if condition after the function return which checks if it was successful or not and only prints the value, therefore there is no logging of the return code by default but I can add the line if that is important for you.

[quote userid="111786" url="~/f/nordic-q-a/121315/possible-bug-cellular-modem-sample-with-nrf9151-running-slm/534565"]Have you seen mentioned errors intermittently? Are errors reproducible on your end?[/quote]

Yes it doesn't work like you can't use cellular_get_signal() function to retrieve those values, the return error is either -16 or -22 from what I have seen which is not consistent. They are therefore reproducible.

Hi,

Thank you for additional information.

[quote user=""]

Everything is working except cellular_get_signal(), I am not using 2G or 3G so it is expected that CELLULAR_SIGNAL_RSSI might not be available, however the calls to that function with CELLULAR_SIGNAL_RSRQ and CELLULAR_SIGNAL_RSRP fail also.

They return either -16 (EBUSY) or -22(EINVAL) error codes (it is not consistent).

[/quote][quote user="tsotnek"]Everything works as expected even if I don't omit those lines, those lines don't really interfere with application. I am able to connect to the server and send and receive the packets.[/quote]

Can you elaborate on the problem you have and the errors you get?
Can you point to the places in the log where errors (--16 (EBUSY) or -22 (EINVAL) error codes) can be seen?
Have you seen mentioned errors intermittently? Are errors reproducible on your end?

Hello,

[quote userid="111786" url="~/f/nordic-q-a/121315/possible-bug-cellular-modem-sample-with-nrf9151-running-slm/534472"]Can you provide more information about your board and interface to nrf9151?[/quote]

The board is custom board that is using nRF54L15, I am just using overlay for nrf54l15dk:

/ {
    aliases {
        modem = &modem;
    };
};

&uart22 {
    compatible = "nordic,nrf-uarte";
    status = "okay";
    current-speed = <460800>;
    hw-flow-control;
    pinctrl-0 = <&uart22_default>;
    pinctrl-1 = <&uart22_sleep>;
    pinctrl-names = "default", "sleep";
    modem: modem {
        compatible = "nordic,nrf91-slm";
        status = "okay";
        mdm-power-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>;
    };
};

&dppic00 {
    status = "okay";
};

&gpio1 {
    status = "okay";
};

&gpio0 {
    status = "okay";
};

&gpio2 {
    status = "okay";
};

&gpiote20 {
    status = "okay";
};

&gpiote30 {
    status = "okay";
};


&pinctrl {
    /omit-if-no-ref/ uart22_default: uart22_default {
        group1 {
            psels = <NRF_PSEL(UART_TX, 1, 13)>,
                    <NRF_PSEL(UART_RTS, 1, 11)>;
        };
        group2 {
            psels = <NRF_PSEL(UART_RX, 1, 14)>,
                    <NRF_PSEL(UART_CTS, 1, 12)>;
            bias-pull-up;
        };
    };

    /omit-if-no-ref/ uart22_sleep: uart22_sleep {
        group1 {
            psels = <NRF_PSEL(UART_TX, 1, 13)>,
                    <NRF_PSEL(UART_RX, 1, 14)>,
                    <NRF_PSEL(UART_RTS, 1, 11)>,
                    <NRF_PSEL(UART_CTS, 1, 12)>;
            low-power-enable;
        };
    };
};

It is connected with UART over the Thingy91x debug extension board.

This is the board Kconfig I am using:

# UART Configuration
CONFIG_NRFX_UARTE22=y
CONFIG_UART_ASYNC_API=y
CONFIG_UART_22_ASYNC=y
CONFIG_UART_22_INTERRUPT_DRIVEN=n

# Align with the Serial LTE Modem (SLM) application.
CONFIG_MODEM_CMUX_WORK_BUFFER_SIZE=1500
CONFIG_MODEM_CELLULAR_UART_BUFFER_SIZES=6000

# Prevent sockets getting offloaded to the modem.
CONFIG_NET_SOCKETS_OFFLOAD=y

# Print logs and printk() output on uart0.
CONFIG_LOG_BACKEND_UART=n

CONFIG_MODEM_LOG_LEVEL_DBG=y

# Disable AT shell as SLM application has no AT mode user pipes
CONFIG_MODEM_AT_SHELL=n

# GPIO Configuration
CONFIG_GPIO=y

On the Thingy91x side I just followed the instructions that are given here on building the SLM application and just flashed that on nRF9151 ( of course setting up appropriate overlays for UART) - docs.nordicsemi.com/.../nRF91_as_Zephyr_modem.html

[quote userid="111786" url="~/f/nordic-q-a/121315/possible-bug-cellular-modem-sample-with-nrf9151-running-slm/534472"]It is not clear if you are using plain Zephyr or NCS. I see from your link that you use Zephyr sample. Can you confirm that you use NCS? In case you use NCS, which NCS and Toolchain version do you use?[/quote]

I linked the zephyr's sample because I posted on Zephyr first and the cellular sample is same on both Zephyr repo and the forked repo of sdk-zephyr. I am using for SDK: NCS v3.0.1 but for toolchain I am not using NCS v3.0.1 I am using zephyr 0.17.0.

Everything works as expected even if I don't omit those lines, those lines don't really interfere with application. I am able to connect to the server and send and receive the packets.

RE: Possible Bug: Cellular modem sample with nRF9151 running SLM

dejans — Thu, 08 May 2025 12:55:27 GMT

Hi,

[quote user=""]I am running cellular modem sample on nRF54L15 and have it interfaced with nRF9151 which is running SLM application.[/quote]

Can you provide more information about your board and interface to nrf9151?

[quote user=""]I posted this in Zephyr's repo at first, but was told to post it here since I am using NCS.[/quote]

It is not clear if you are using plain Zephyr or NCS. I see from your link that you use Zephyr sample. Can you confirm that you use NCS? In case you use NCS, which NCS and Toolchain version do you use?

[quote user=""]These are the debug logs including modem_chat[/quote]

Can you show complete log?

[quote user=""]P.S. I only added couple of new lines in print_cellular_info() function to try to fetch RSRP and RSRQ[/quote]

Is everything working as expected if you omit lines shown below?

    rc = cellular_get_signal(modem, CELLULAR_SIGNAL_RSRP, &rsrp);
	if (!rc) {
		printk("RSRP %d\n", rsrp);
	}

	rc = cellular_get_signal(modem, CELLULAR_SIGNAL_RSRQ, &rsrq);
	if (!rc) {
		printk("RSRQ %d\n", rsrq);
	}

Best regards,
Dejan
