Ble app_blinky on pca10056 not working with interrupt.

[Liverpool007]

1. I have written an interrupt program to blink an led at port P1.01 by pressing the button 1.So i added the code in ble_app_blinky example so i can blink the led from the board and use the mobile app to connect to the board and blink the led. But once i add the interrupt program code in the main program the board stops advertising.any help.Both the codes are working individually.here is the code

Have you tried debugging the example either by using an RTT client & NRF_LOG_INFO calls or via the IDE you are using? 

[Liverpool007]

i called  the gpio_init() funtion first and now its working.

In this program i am keeping track of the number of times the button is pressed.

Now i wanted to upload the count(which is stored in pulses) to the nrfcloud how can i do that?

[Bjørn Kvaale]

Good to hear that you got it working! This youtube video gives a nice intro of nrf cloud. See this link for getting started with nrf cloud. There is a quick start guide link at the bottom. Currently, the beta release provides software for using the nrf connect application on PC as the gateway between your nrf52 DK (I am assuming this is what you are using ??) & the nrf cloud. It should soon be possible to use your smartphone (Android or iOS) as the gateway to the cloud. Using the PC as a gateway should work out of the box. Good luck with further development!

Update: The nrf cloud gateway apps are available on Android & iOS (just search for nrf cloud gateway in Google Play Store or Apple App Store).

Reminder: Next time, it is better practice to ask a new devzone question because your second question is quite different from your first question. If the followup question is quite similar, it is fine to keep it in the same question, but otherwise create a new question. That way, it makes it easier for others that have the same question to see the answers.

[Liverpool007]

i have set up the nrf cloud. i only cannot upload the integer data to the cloud

[Bjørn Kvaale]

Could you be more specific? What errors are you getting?

Have you downloaded the nrf cloud gateway app on iOS or Android? You should be able to connect to the smartphone gateway, which should then let you pass the int data from your peripheral device (i.e. your 52840 pdk) via the gateway to the cloud.

 

[Liverpool007]

Inorder to write data in the characteristics i followed this tutorial-link.The the toggling and uploading of data is working .But once i add the interrupt code the program does not work ,it stops running when i call the gpio_init() funtion ,similar to the problem above and i get an error no 8[NRF_ERROR_INVALID_STATE].I am using nrf connect on pc.

[Bjørn Kvaale]

Which one of the functions inside gpio_init() returns NRF_ERROR_INVALID_STATE? You can check this by either adding more NRF_LOG_INFO() prints inside the gpio_init() function & using a segger real time terminal viewer for example to see where the error state is returned or by debugging your example.

You are using two nrf52 DKs, right (or a nrf52840 PDK & a nrf51 dongle)? One that is running your application & another one that enables the Bluetooth communication from the application DK to the gateway running on your PC. Is this correct?

It might be that your application device is not yet connected to nrf connect on PC & while you are still connecting to the gateway, you try to run the gpio_init() function maybe (see link). Are you still calling the gpio_init() function at the beginning of main() or right before advertising_start()?
