Hello Ramiz,

Did you receive my email with the working application? It is ready for you to test, it works on my end. Please let me know if you did not receive the link to the application code.

Thank you,

Jennifer Gibbs

Please reactivate the case and provide status of the test.

There is no progress. I am awaiting the feedback from Naeem/Support Engineer on the status of testing and demonstration of the working operation of the Tx/Rx port in the nRF9161 using example 5 of the academ.

FAE team contacted Ramiz.

Moving case to Waiting until next update.

despite many attempts - these Zero progress.

Did you test in your lab with nRF9161 and made it work?

Hi,

I hope you made some progress on your side after that meeting.

Is there an update? Are you still getting some issue? If yes, then it will be great if you could share some snaps and describe the issue.

Did you get invite? I sent on your email (from your profile).

By the way, i can also meet tomorrow (saturday) to address this as it is becoming urgent to solve this issue. Please let me know what is possible on your end.

i prefer today as i need to demo something to my mgmt on Monday (i am behind demonstrating the operation of this). Please ping ASAP to sort out how to solve this issue.

RE: Can't get UART to work via GPIO interface

RamizB — Fri, 12 Jul 2024 16:57:33 GMT

yes

Naeem Maroof — Fri, 12 Jul 2024 15:53:31 GMT

Are you available for online meeting now? Or else we can do on Monday.

Naeem, i am struggling making my deadline to make this small/simple code (from Nordic) to work. It has been a while with NO progress. I really need your help to check the code base i sent and let me know your advice to make it work.

give how this code work, the description talks about the Console. What is the console connected to? i can't find a document to describe the console port concept.

Looking forward your support and detailed feedback about the code and the console.

thanks for your help in advance.

can you please allocate time to be online with me while debugging?

RE: Can't get UART to work via GPIO interface

RamizB — Wed, 10 Jul 2024 16:42:28 GMT

which logs, where to find them?

RE: Can't get UART to work via GPIO interface

RamizB — Wed, 10 Jul 2024 16:41:41 GMT

and there are no error messages

RE: Can't get UART to work via GPIO interface

RamizB — Wed, 10 Jul 2024 16:40:58 GMT

the return values are:

ret get a value of zero

the rx_buf is empty (i.e. all elements are zero)

any chance you can help look at the code realtime while it is running? this is really slow and i need to move fast

[quote user="RamizB"]Yes it does run and it turns no the 3 LEDs correctly. But the " ret = uart_rx_enable(uart ,rx_buf,sizeof(rx_buf),(-1));" does not get anything![/quote]

In the exercise solution, or in your code?

And what you mean by "does not get anything"? Does it produce error? What are the logs you see.

thanks for the update. Yes it does run and it turns no the 3 LEDs correctly. But the " ret = uart_rx_enable(uart ,rx_buf,sizeof(rx_buf),(-1));" does not get anything!

I know you are busy, but is there anyway i get faster response or even better connect in real-time to help look a this holistically for resolution?

RE: Can't get UART to work via GPIO interface

Naeem Maroof — Mon, 08 Jul 2024 13:45:07 GMT

Yes, uart_configure() inside main is okay.

I want to ask whether you were able to successfully run the exercise solution or not?

I think you first you should make it sure that there were no problems in running that exercise and then make the changes.

Hi Naeem,

thanks for the feedback. Two points:

Point 1:

Regard the call of uard_configure(), it is inside main as follows:

int main(void)

{

int ret;

int err = uart_configure (uart, &uart_cfg);

if (err == -ENOSYS) {

return -ENOSYS;

}

do you agree?

Point 2:

when i use the dubug function and check the start of the UART per the following code:

/* STEP 4.2 - Verify that the UART device is ready */

if (!device_is_ready(uart)){

printk("UART device not ready\r\n");

return 1 ;

}

i get invalid answer in the Watch window for watching: "device_is_ready(uart)"

why is that?

Hello

Were you able to get lesson-5 solution work on the DK without any modifications?

9161DK is mentioned as a supported board, so it should work without any issue.

Also, I have noted that you are calling the function uart_configure()outside of main. You should move it inside main.
