Getting Notifications from BLE using nRF 52480 dongle PCA10059

[nagendrababu21]

Hi,

OS: Windows 10

SW used is Segger IDE, nrfCOnnect for desktop to program HW used is nRF 52480 dongle PCA10059 

I am starting using nRF 52480 USB dongle, I need to connect to the other peripheral BLE device and receive its notifications. I read through all central examples, i am unable to connect using NAME and address. Kindly help and provide any sample examples. I need to connect to one BLE peripheral and receive the notifications and route the notifications to the PC using nRF 52480 dongle UART.

Hi,

Kindly refer this tutorial : https://devzone.nordicsemi.com/guides/short-range-guides/b/getting-started/posts/nrf52840-dongle-programming-tutorial as a starting point for developments using nrf52840 dongle. Furthermore, there is nRF desktop application that demonstrates configurations for dongle. You can try testing the dongle by running a separate DK as a peripheral (mouse or keyboard) and send data to the pc through the dongle. We will be uploading a blog explaining nRF Desktop application in the coming days and I will update the link once it is available.

Hi 

Thanks for the help. I have also arranged nRF52840 DK PCA10056 for debug purposes, I have a device(peripheral) which is emitting notifications every second once connected, now i need nRF52840 to act as central connecting to that device and receive/collect those notifications and print it on serial(uart/RTT). How can this be done. i am able to do the same in nRF connect mobile application with the screenshot attached. I need to emulate the same thing on dongle/ nRF52480. Kindly help through the process.

I need to receive those values

I also tried with HRS example in the SDK but could not achieve the same. Where would i have been missed?

To add to this I am unable to get notifications in nRF Connect Desktop Application too.

Hi Nagendra,

Regarding the issue you are facing with BLE app, this is weird.. The BLE app nRF Connect for desktop should work in the same way as the nRF Connect mobile application. You should be able to receive the same notifications that you receive in the BLE application. You could try to disable the mass storage class on JLink. (Note: this may cause problems on Windows even though only mac and linux are mentioned). Hopefully, it will resolve the issue that you are facing with the BLE app.

Hey,

Regarding the first part of your question, what you basically need to achieve is to receive the notifications from your peripheral device and print them on UART which sounds similar to UART central application. As for the HRS sample, there are two samples - one peripheral and the other central, both of which uses UART. Either the UART central application or the the Central Heart rate monitor with coded PHY application can be used as a good base to start developing according to your requirements.

Hi ,

Thanks for u r guidance. Which is the UART UUID and code changes which I need to change in the central UART application so that I can start receiving notifications from my peripheral device.
