Hi Nordic Support Team,
I'm currently experimenting with Channel Sounding using a couple of nRF54L15 boards.
I am trying to obtain raw I and Q samples so that I may analyze...
We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...
Hi,
I do receive undefined HCI errors in my disconnection handler. I wait for the BLE_GAP_EVT_DISCONNECTED event and use the bleEvent->evt.gap_evt.params.disconnected.reason...

We are using two GPIOTE inputs and there is only 1 GPIOTE interrupt handler.
One of the GPIOTE input is from a power line chip that toggles @ 50 Hz rate. This GPIOTE input...
Hi Team,
I was trying dfu to load my application.
Edit #1
I have flashed softdevice.
Then I have compiled the example project 'dfu_dual_bank_ble_s110_pca10028...

I am able to read the temperature on the...
I would like to use the single shot timer and when the timeout handler is called, I would like to set up the same timer again with different interval this time. Do I have...
There seems to be a discrepancy between the 8.0.0 softdevice release notes and the product compatibility matrix. I would like to know if it is possible to use 8.0.0 softdevice...
Hi,
In my project, I need to periodically perform some jobs on the nRF51822 Beacon kit (sdk 7.1). For that, I think I need to use timers. However, I'm not sure how to do...
Hey everyone.,
I was trying to use nrf51822 as spi slave and just a heads up to know that i use Nrf51822 as master. I see that when chip select CS gets low SPI needs to acquire...
I've added a custom service and a few characteristics on the nRF51822. How can I access the current value stored in one of those characteristic outside of a BLE event occurring...
Hi,
I'm unable to run any application on nrf51 DK (Keil used). When I start debug (no matter what application I load), program always cycles between 2 instructions:

Hi,
My application uses the softdevice 110.
Everytime, there is an event on my sensor. The sensor sends the event to my pin, which generates a gpiote interrupt . But, the...
Hi,
I'm trying to determine why a HCI DFU upload fails.
