Hello,
I'd like to ask what is the data rate when using BLE OpenMesh network and how much it depends on network architecture.
I'm considering using it in a network consisting...
Hello Nordic Community,
I need to know how to import my PCB design from Eagle to CST Studio to simulate it and I need to know if the simulation step will be useful to enhance...
Hi.
I'm trying to get Apple notifications to nrf52. And specifically to listen both regular ANS (for android) and ANCS (for iOS) events depending what sort of phone is...
I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
The documentation clearly state that if the payload length is read as > 32 byte, the RX FIFO must be flushed.
My question is, will that erase all other pending messages even...
How much current can the nrf51822 sink per pin? In the datasheet, I can see that it is at least 5mA. I also see that the chip can drive 3 pins at 5mA, but can it handle more...
Hi
SPI master is 3rd party MCU. SPI slave is nRF51822.
If MCU sends a bunch of data to nRF51822 via SPI, at the same time, BTLE host like celluar phone try to connect...
Hi,
I am using the PCA10001 v1.0 from the development kit and am having trouble measuring the same current as the one from the specification.
I am using the ble_app_proximity...
Hi,
According to nRF51 Series Reference Manual v1.1 , section 10.1.3 there are 3 ways to leave debug interface mode after programming the chip. Assuming that my device...
Hi
i created one timer0 interrupt in ble_app_hrs.
void timer0_init()
{
NRF_TIMER0->TASKS_STOP=0;
NRF_TIMER0->PRESCALER=4;
NRF_TIMER0->BITMODE=3;
NRF_TIMER0->MODE...
I am new to ARM and nRF51822. I am using a development kit with the PCA10000 dongle and the PCA10005 daughter card. I wrote a simple C program (attached) to blink the LEDs...
Well, I'm a little in doubt on whether this is the right place to file a bug in the reference manual. Anyhow, I think it's easier and maybe it will prevent that another guy...
Hello,
I updated the "ble_app_proximity" PCA10001 example for adapting the time constants of my needs.
#define MIN_CONN_INTERVAL MSEC_TO_UNITS(3700, UNIT_1_25_MS)...
hi,
In my device(nr51), have multi service and one client.
when i initial the client first ,then to setup service. this follow is O.K.
But, if i initial the service, and...
Keyboard source: Desktop 2 v1.0.5
Dongle source: 1. Desktop 2 v1.0.5 dongle hex; 2. Desktop 1.2.2.293 dongle hex
I found it is very defficult to pair the keyboard with...
Hi,
1. I have some puzzles,please give me some explanations,thank you!
In my design,I use some 51822 devices as tags which can communicate with the host.
The tags can send...
Hi, I want to know what's the differences between the NRF_CLOCK_LFCLKSRC_RC_250_PPM_xxMS_CALIBRATION and NRF_CLOCK_LFCLKSRC_XTAL_xx_PPM where xx means a decimal number.
when...
We've been working on a product that utilizes a NRF51822 chip as well as WS2812B NeoPixels. Since there have been numerous posts about it here we've decided to release our...
