we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
HI,
We connect our own board with nrf51 via UART. From the host board, I call sd_ble_gap_rssi_start() first. I can see BLE_GAP_EVT_RSSI_CHANGED happens. Then I call sd_ble_gap_rssi_get...
We are all familiar with NRF_MODULE_ENABLED macros, what is their purpose and why are they required.
However, I am wondering if there could be a better way to implement...
Hi,
I am trying to get the example spi slave working. I am using SDK 11.0 ( I will try again under the 12.0 SDK later today).
I've checked my spi master by running the master...
Hi,
I am trying to interface MCP2515 with nrf51-dk. MCP2515 talks over SPI, so I have taken SPI_master as my base code. I have used MCP with arduino, so I thought it would...
Hi DevZone,
I am Nordic beginner, I am using the Nordic SDK example code for my current project. Before using Nordic DK, I was using Arduino for this project.
There are...
I'm trying to enable the S140 softdevice on my nrf52840-PDK from NuttX. When I call sd_softdevice_enable(), it returns NRF_ERROR_INVALID_FLAGS, which is not one of the documented...
I hope, operating BLE 5.0 at low data rate will give us longer range in open space. So in an environment like a football field, where each player will have 5.0 operating devices...
Hello,
I tried to add the code of the bluetooth tutorial called "Bluetooth low energy Characteristics, a beginner's tutorial", with a code that measures the delay of two...
Hi
I am working on a design using an nRF24L01+ in a circuit also consisting of an ATMEGA microcontroller and a H-bridge motor driver driving a brushed DC motor. The whole...
hi all!
I would like to ask the DCDC and LDO two modes of choice. My product is a watch, it uses the cr2032 battery dropped to 2.5v by an external LDO to 52832 power supply...
Hi,
I am using nRF52832 development kit PCA10040 V1.2.1 2017:38. I am able to successfully run nRF_Examples\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral...
hi,
I am using PCA10040 v0.9.0 Nrf 51 DK.
In schematic I am not getting connection for programming connectio n .In sheet 4 of 5 at the USB Connector connection signal...
Hi,
I m trying to develop an linux-application running on node.js to communicate with a nrf52 device. I m using the noble-module ( noble ) and a usb bluetooth-dongle. ...
Hi,
Is it possible to connect nRF905 to nRF51822 via SPI, add ShockBurst code nRF51822 and then use alternately/simultaneously Sub GHz and Bluetooth communication?
I'm...
Is there nRF Connect or similar program that enables development of BLE applications for Windows 10 (using native BLE API - ideally universal windows platform)?
