Cloud Client App Message on Event

[Muhammad Usman]

Hi All!

I am using the cloud client example. The development board is nrf9160. This example works well and sends the message to nrf cloud on button press. Is it possible that it sends the message to a cloud client on an Event? Like when some Uart Interrupt occurs or a timer expires.

Thanks in Advance!

Hi All!

When I set "CONFIG_CLOUD_PUBLICATION_SEQUENTIAL=y" in the .config file.It successfully sends the messages to the cloud at a regular interval, it's working fine! 

Now I want to edit my previous question, I need only to send the message to the cloud upon the UART interrupt occurrence.

Thanks In advance!

Hello, 

What UART interrupt do you mean? Have you looked at the Zephyr Scheduling, Interrupts, and Synchronization?

I did not have time to look into your issue today but will have a look first thing tomorrow. 

Kind regards,

Hello,

Thank you for your response! Yes you are right i am talking about this 

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.8.0/zephyr/reference/peripherals/uart.html

I added the UART Interrupt code into my cloud client code and it's working fine.

 struct device *uart = device_get_binding("UART_1");

    uart_irq_callback_set(uart, uart_cb);

    uart_irq_rx_enable(uart);

    printk("UART loopback start!\n");

Now my question is, how can I send the message to nrf cloud ? I am saving the incoming message from uart interrupt into an array and now want to send it to nrf cloud. Any idea? 

Thanks in Advance!

Hi, 

Good to hear that you have added the UART interrupt. From the Cloud Client documentation you should be able to use cloud_send(). This function is called in the cloud_update_work_fn(). In this function you can see that it sends CONFIG_CLOUD_MESSAGE, defined in the Kconfig. You will need to do something similar in your uart_cb.

Kind regards,
