Hello, this is probably a very beginner question but I don't know how to configure interrupt for the GPIO headers on the nRF52840 dev kit. I tried to search in this forum...
Hello,
I'm looking for answers and some explanation for two main questions - is it possible to perform non-simultaneous multi-image FOTA over WiFi? Is it possible to support...
We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...
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;

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,
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.

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...
Hi,
I want the NRF51 to respond to a received packet from a particular device using register TIFS to control the interfame timing.
For TIFS to work I have to set the...
