Instead of printing those, can you try to use debugging and create a breakpoint at the same place.
Then add a watch to p_cli and inspect it to see if it have the data you need.

Hello Sigurd,

I added the following logging:

I added this part of code:

    NRF_LOG_INFO("p_cli->p_ctx->cmd_buff:");
    NRF_LOG_INFO(p_cli->p_ctx->cmd_buff);
    NRF_LOG_INFO("p_cli->p_log_backend:");
    NRF_LOG_INFO(p_cli->p_log_backend);
    NRF_LOG_INFO("p_cli->p_ctx->temp_buff:");
    NRF_LOG_INFO(p_cli->p_ctx->temp_buff);

My debug terminal looks like this:

<info> app: p_cli->p_ctx->cmd_buff:
<info> app: "
<info> app: p_cli->p_log_backend:
<info> app: Ì?
<info> app: p_cli->p_ctx->temp_buff:

There is no usable information for me.

By implementing my logging like this, I will not be able to catch, if there is a command received, as there is so many data with no information to me.

Can you suggest some positions to log only the communication with the received ascii characters from my pc?

Best regards,

Michael

Does it log anything at all?
If so, what does it log?

Hello Sigurd,

I tried to log something in the nrf_cli.c file in the nrf_cli_process(...) function:

NRF_LOG_INFO(p_cli->p_ctx->cmd_buff);
NRF_LOG_INFO(p_cli->p_log_backend);
NRF_LOG_INFO(p_cli->p_ctx->temp_buff);

But there is no useful information for me.
Can you provide me some suggestions what to log?

Thanks and best regards,

Michael

In that case, I would start at the function nrf_cli_process, described in nrf_cli.h as:

"Process function, which should be executed when data is ready in the transport interface."

Note: I did not test this myself, but seems logical. If it does not work, let me know and I will try to find something better

Hello Sigurd,
thanks for the reply.
We want to take a look at the ascii stream of the cli interface which is received by the nRF52840DK.
We have some commands registered, but sometimes they were not triggered on the nRF52840DK. So we want to take a look at the full ascii stream which the nRF52840DK receives to check if maybe the command is not received correctly or if the command is not even in the cli interface at all.
Best regards,

Michael

I can try to do so.

Can you specify a bit more which CLI data you want to have a look at?

Hello Sigurd Hellesvik,

thanks for your reply.

Can you please provide a more specific place to set a checkpoint or to do some logging? As the nrf_cli.c for example is pretty huge.

Thanks and best regards,

Michael

Hi,

You can see our cli libraries at components/libraries/cli/.

Here, you can either use checkpoints from a debugger
Or you can add logging to the source code
