Hi everyone,
Currently, I am working on my bachelor thesis for creating simple network by using MQTT, BLE-6LoWPAN and nRF52832. I have three nodes of 52832 and one raspberry...
Hello everyone!
I want to form an Openthread network with three Nordic nRF52840 cardboards. I would like to monitor the traffic using a sniffer, but i can't receive any...
We are using the development board PCA10040 for implementing a prototype with several GPIO interruptions.
We are trying to use the NFC pins (pin 9 and 10) as pins of GPIO...

It seems the LTE-M / NB IoT isn't available Europe-wide yet, and roaming applies country-wise.
Can anybody share his/her experience of using the BLG840F?
thank you.
Hi,
I am trying to build a thread network using a border router nRF52840 with a Raspi3B+ and 2 others end-devices nRF52840 connected on a CPU Ubuntu 16.04 LTS.
I have...
In Mesh SDK, there are 3 versions available for s132 softdevice: s132_3.1.0, s132_4.0.4, s132_5.0.0.
The question is, should I always use the latest version available? If...
Before I use 51822QFAC(with 32K RAM)， add I must use 51822QFAA(with 16K RAM)。
I have modify IRAM area，like this
IRAM: 0x20001FE8 0x2018.
and selete device is 51822QFAA...
We are designing the nrf52840 with high voltage mode and both DCDC regulators.
Where can I find the requirements for the external circuitry, like the inductors. For now...
Hi,
1. what the DC2DC switching frequency of nRF52832?
2. at nRF52840 the inductor should be 10uH with tolerance +-10% but for nRF52832 this inductor can be with tolerance...
Hey everyone,
I've been trying to get this basic bare-metal application to work. I don't need a softdevice as I'm just trying to turn on an LED. The application compiles...
Could not connect to the nRF52840 preview DK eval kit running the ble_peripheral/ble_app_uart firmware to iOS 11 device running the nRF connect or toolbox apps. We tried on...
Hi:Nordic
Because the nrf52832 can't read 8bit parallel data from GPIOs to RAM with EeayDMA . So I want to use 3 SPI simultaneously to write data to ram with EeayDMA, can...
Hi there,
I have a issue with the nrf51822 UART baudrate setting.
I am developing nrf51822 dongle, its job is to transfer data between PC and a BLE periph. For a stable...
Hi, is it possible for the 824 chip to sleep until woken up by the Bluetooth of a nearby device that wants to connect/pair with it? And what would be the current consumption...
Hi,
As part of my watchdog flow, I'd like to test the liveness of the softdevice and the SDH during operation.
Is there a built in way to trigger the softdevice to post...
Hai
whether Bluetooth 5.0 in nrf52840 Compatability with Bluetooth 4.2 available on my phone, I heard that Bluetooth 5 is lower compatible. I like to know whether it has...
I am looking a way to send a string without the terminal, ble_nus_string_send function only works in the uart_event_handle() and APP_UART_DATA_READY is only triggered when...
I am writing a library for Nordic nrf52832 and it uses some of the functionality from fstorage ( fstorage_nvmc implementation) to access the NVM. The library creates only...
I have some functional code working on an Adafruit nRF52 Feather board which I am trying to change over to run in embedded C on an nRF51 dongle. I am using Adafruit nRF52...
Good evening, I'm trying to understand how to use the SDK 12 to connect peripherals using PPI such that when an address match occurs (say on pipe 1's address+prefix), a timer...
