Please,
It seems that "Flow Control" signal is not available on nRF24AP2-USB.
EVENT_TRANSFER_TX_START event message appears only one time after the first data packets...
I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
In the sensor datasheet it says one can use SPI_Mode 0 or 3 (doesn't say that there is anything to do to switch between them).
I connected MISO from the DK with SDO from...
I want my application to cooperate with DFU. I am using example DFU project from SDK (6.1) (from nrf6310 folder, i simplified it so it could work on PCA10000), but i need...
I increased my IRAM1 size as advised here , but now my program doesn't work anymore on the nRF51 DK.
I know the problem is somewhere in the memory allocation, because when...
I am working with nrf51422 chips version 2, so according to this table taken from the compatibility matrix v2.0, the last supported versions of SDK/SD/SDS I should refer to...
Also it seems not to advertise. What may cause this problem?
All I could found in the ble_gap.h is:
If both conn_sup_timeout and
max_conn_interval are specified...
Hi
I am trying to debug the "ble_app_hrs" example from SDK 6.1.0 (using keil IDE), on 51822 chip.
The IROM1 is defined to start at 0x16000 (meant to be used with softdevice...
I'm trying to minimize current consumption on my BLE peripheral and I wanted to know what advertising data is required. I have a custom service with a 128-bit UUID but do...
Hello!
I am using a keyboard (4x3) and the rows are configured as input PD and columns as output set, after a successful interrupt , the columns and the rows shift settings...
I am using nRF8001 bluetooth ble for my project. I would like to get the RSSI value as a reference value in my firmware. Is there any way that I can get the RSSI value from...
Hello,
I'm using the following (nRF51822-Beacon): www.nordicsemi.com/.../nRF51822-Bluetooth-Smart-Beacon-Kit
I would like to use the beacon for beacon-to-becaon and...
I am calling the spi_master_send_recv in a ISR from a GPIO using app_gpiote.c It causes a hardfault on APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type)); Otherswise...
Hi,
The nRF Toolbox app on iOS crashes when opening user added files in the DFU. These files are added to the app via iTunes. The version of the nRF Toolbox is 1.7 which...
Hi,
We're producing a custom board based on the nrf51822 and would like to add a USB Serial chip.
The current contenders are:
a) FTDI 232R
b) ATmega8U2 ( www.arduino...
