Hi I've just nrf5340 DK, I am going to start implementing OpenThread on it but I've not found any article on how we can start. Please provide full article from start and support tools and ide Thanks & Regards Ajit kumar

My application requires mathematical calculation based on double and float. For this I have included <math.h> in the header files. FYI : I am using NCS 2.2.0 Also included - CONFIG_NEWLIB_LIBC=y CONFIG_MAIN_STACK_SIZE=8192 CONFIG_BT_HCI_TX_STACK_SIZE…

I am connecting to Nordic nrf9160 from linux through PPP of modem shell application for internet connection. I am observing very slow internet speed where it is taking approximately 1.30 minutes to download 1MB of data. Below are some test results. …

Hello, We are developing an application to work as a multilink central with 3 different kind of BLE devices that include 1 custom device which advertise customised NUS service, 1 Polar belts which advertise HRS, BAS and DIS services and 1 EMG sensors…

I'm using " no.nordicsemi.android:ble" and " no.nordicsemi.android:ble-common" on a tablet app, and had created a virtual device(Polar HR) on my iPhone with LightBlue app. When I connect I received the event through ConnectionObserver, also when I locally…

1. We use code similar to the existing sample code to repeatedly sample a 0 - 2.25V voltage range using the SAADC. 2. Settings: 30s interval, single-ended input, burst-mode, internal reference 0.6V, triggered via PPI or by MCU (doesn't seem to matter…

Hello Devzone, Our research group is using the NRF52832 chip embedded in a flexible substrate to transmit EMG (muscle) signals via Bluetooth. We’ve been having a couple issues with our device and have isolated two issues to the NRF chip. For some background…

Very much a beginner at this so if this is inappropriate for this forum do not hesitate to let me know. Starting out trying to develop a BT Mesh system. I purchased a nrf53 Dev Kit, a couple of Thingy:52 devices, some standard BT-Mesh Light Bulbs and…

I'm trying to develop an Android app to get the BP, HRV, HR, SpO2, ECG, PPG, BPM, steps, activity, temperature, sleep quality from Spovan H02 fitness tracker ( www.spovan-en.com/.../2669112013571072.html) which uses NORDIC 52832 CPU and SI1182 sensor…

Hi Community, I'm a little bit flyiing in the dark, so I like to ask this in the devzone. Does anyone already implement NFC OOB Pairing and using Apple GymKit? 1. NFC OOB Pairing MUST work on iOS on the same way as it does on an Android Device…

Hi everyone, Is it possible to implement a USB device belonging to the Personal Healthcare class with the nordic nrf52840 DK? NRF supports Personal Healthcare USB class? I don't find any examples in the SDK, are there similar discussions I can take…

Hi, I'm trying to implement a SPI Communication between Arduino UNO and PCA10056 DK. PCA10056 DK run as a SPI slave.. Arduino uno run as a SPI Master. The problem is SPI Master keep sending a chunk of data (size - 25 bytes ) by each second.. But…

Hi Everyone, Last two weeks I'm trying to make a Real time streaming custom service on PCA10056 DK. I have modified the ble_image_transfer code according to my requirement. The problem is 1. After Connect to nRFConnect ..its automatically disconnecting…

Hello ,I just buy nRF5340 pdk and look at user guide https://infocenter.nordicsemi.com/pdf/getting_started_NCS_nRF53.pdf . I installed nRF Connect in my PC, and flash HEART HEX to nRF5340. I installed Nordic nRF Toolbox app in my smart phone for Android…

Hi, we are using nrf52832 in our product and it needs external storage 8MB. Please suggest flash storage IC that has driver support in SDK by default or which has ready made driver available for nrf52832. Thanks,

Hi, In the I2C communication,the nRF52840 SoC is master, the sensor SCD 30 is slave. The sensor SCD 30 needs the clock stretching period, the period time is 12ms or 150ms. The first step is to get data ready status, the I2C command is 0x0202. I used…

I'm planning not to have a device name UUID in the advertisement packet, instead set scan filter based on manufacturer-specific data. Is this possible in SDK16? If so please let me know how?

I have nRF52840 as the central and nRF52832 as the devices. I have the device names as TELCO_456, TELCO_457, TELCO_458 in the connectable advertisement packet. I have disabled auto connect in the central and I want a scan interrupt when these peripheral…

Dear experts.. we are trying to build a 12 lead ecg system which sends real time data to mobile phone for plotting using nRF52832. While most of the time it works ok, when we vigorously shake the phone, a huge data loss can be observed. the phone used…

Hi all I am using nrf52 with max30003 to read full ECG and send it over BLE. My data is acquired at 128SPS. De default GAP settings are too slow to receive all the needed ECG data. What can I do? I thought of reducing the connection interval…

I have being confused by other post around DevZone about DS18B20 to integrate with nRF BLE application or rather programmatic aspect is concerned . Is DS18B20 suitable for such application especially with nRF52 as far as integration and application is…

Hi all: Our usage scenario is to establish a connection and bonded between the NRF52840 peripheral device and the central device, and then restart the NRF52840 peripheral device at this time. I hope that the NRF can actively connect with the newly connected…

I need to interface a MAX30003 IC via SPI to a NRF52832 via SPI. I am currently developing the hardware and thus my question: MAX30003 need an external 32.768kHz clock. is it possible to share an external clock between the MAX30003 and NRF52832…

Hi, I am working on one business use case. The basic requirement is to monitor the outdoor air environment from different locations. I want to try out the initial things with Nordic Thingy 52. Where can I log the data coming from Thingy sensors? How…

Hi, How to update modem version from 1.1.1 to 1.2.0 version by OTA. "mfw_nrf9160_update_from_1.1.1_to_1.2.0.bin" flie is missing in zip. Thanks, Bala
