Good Morning,
I'm currently developing an application for the nRF54L15 where I only need to send single BLE packages, therefore arising the need for keeping track of the number of packages sent which is not provided for default BLE advertising.
As…
Hi,
I am using NRF58233 sdk and I am currently using 'NRF_SDH_BLE_OBSERVER MACRO' API to get the softdevice ble events. However, the observer calls my event handler on every ble event regardless of the GAP role. is there any observer similar to ' NRF_SDH_BLE_OBSERVER…
Hello,
Maybe someone has experience with libuarte library? I want to apply nrf_libuarte_async.h library to nRF52810 microcontroller. Does anyone have examples? Thank you in advance Best regards, Andrius
Hello. I want to use sensor.h library for setting interrupt trigger for PMIC. The interrupt should be triggered when event from charger and temperature occurs (e.g. ntc cold, charging completed etc.) I have used this documentation as a reference : https…
Hi Nordic Semiconductor team,
I'm working with the nrf52840 MCU and I have a system off and system on routine and it's works properly (400nA current consumption in system off and 3.3µA in system on). The routine switches to system on when a button is…
I am currently facing an issue with the 'sd_app_evt_wait()' function in my nrf51 application. Despite using this function to put the microcontroller into
sleep mode and wait for BLE events or interrupts, it appears that the sleep mode is not being entered…
Hello, I am using the 52805 in a product and have achieved low power successfully.
I have a final requirement that I am trying to solve and want to know if there is an event generated when the device is advertising, so that I can execute a timer function…
Hello. I have a problem when using nrfx_saadc. I try to start the sampling right after the SAADC offset calibration, but it doesn't happen and the program hangs. Only if I add a delay(4ms) before the measurement, then everything works as it should. I…
I am using the following code to enable the softdevice s130, which seems to run successfully:
err_code = softdevice_enable(&ble_enable_params);
APP_ERROR_CHECK(err_code);
// Subscribe for BLE events.
err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch…
I have built a system with 2 MCUs communicating through I2C. The NRF52 is I2C slave and the other MCU is master. I have implemented a command style interface which sends commands to the NRF52 (I2C writes, TWIS RX) followed by a I2C read (TWIS TX). The…
Hi, I need to read out the Gyro Data of an LSM6DS3TC-R via I2C/TWI. The xiao nrf board uses an nrf52840 and has the gyro sensor build into it, so I don't have access to the pins with an oscilloscope. I know the connection as it is drawn in the schematic…
Dear Nordic fellows,
I have a nRF52832 and I want to use Nordic UART Service to send data in peripheral mode. What is the proper way to use this service? . I'm using nRF5_SDK17.1.0
The ble_app_uart example performs a do while loop with condition err_code…
I'm browsing the Application Event Manager code, and I'm wondering:
I see that struct event_type has (effectively) an array of struct event_subscriber , bounded by pointers .subs_start and .subs_stop .
And, I see that when an event is submitted (using…
Hello,
For my application I have a need to buffer data for, say, 8 GPIO pin outputs and continuously generate those buffered outputs in parallel on the GPIO pins. I have been able to set this sort of system up with STM32's and am now evaluating the…
hi ,
I'm testing this example sdk17.1\examples\peripheral\usbd_audio\pca10056\blank\arm5_no_packs.
I tested the microphone and the headphone separately.
For microphone devices, I found that data could only be sent successfully if the recorder on…
Hi,
I have implemented the nRF5x-Custom-BLE-Service-Tutorial ( https://github.com/NordicPlayground/nRF5x-custom-ble-service-tutorial ) using nRF5 SDK 17.1.0 on my nRF52 DK using Segger Embedded Studio. The used Softdevice is S132.
At the end of…
Hi,
I have noticed that when a peripheral (using NUS) is disconnected from a central it takes 2-3 seconds for the peripheral's BLE_GAP_EVT_DISCONNECTED to trigger.
Shouldn't the event occur the moment the central is disconnected? Why this 2-3 sec…
Hello, I'm working with the event manager doing a customized Asset Tracking version firmware. The problem is that when I attempt to submit an event with an array with fixed size, the app crashes, I can't figure it out where the problem is. This is the…
Hello Nordic Semiconductor
I am developing a small application on the nRF52840 development kit where I need to transfer I2S signals in/out of the MCU. I have set up an I2S_IRQHandler() that gets triggered whenever EVENT_TXPTRUPD gets set. However, I…
Hi,
I am trying to get a simple LED blinking using a timer, gpiote and the ppi. So the Idea is:
Timer compare event -- PPI --> gpio toggle. I am using the nRF connect sdk version 1.9.0.
My main.c is pretty simple, only containing the basic code…
Hi All,
I am using nRF52 DK board & nRF5_SDK_17.1.0 for Development(Emulated Project for nRF52805), My application needs creation of multiple service and multiple characteristics . So, I created a Service of two characteristics as shown in code snippet…
I am still learning how to develop on the nRF52 DK. Nevertheless there are many BLE devices in the market that change their own characteristic / attribute values after connection has been established and some criteria is met. For example, in the following…
I am working on an application where I need to start pwm sequence after particular delay (accurate delay of multiple of 100us).
I am quite new to nordic environment.
Here is my code . Can please guide me what is wrong here??
#define Period 20000…
Hi,
I am also facing same issue i am able to read the version register correctly and able to perform self test successfully
I am using 17.1.0 n RF5 SDK
I am developing NRF52832 DK. in Linux ubuntu OS and my board is PC10040
I'm building library…
Hello All,
I have taken usbd_ble_uart_freertos example and modified it for USB MIDI example (taken from Github) for nRF5 SDK and modified it to use nRF52833 SoC.
I am using Segger Embedded Studio on Windows 10 PC and EVK of ublox having NINA-B406…
