Hello everyone,
I got a task which I try to implement using a NRF51822 iBeacon board.
The Task:
Advertise a Device and provide a mechanism to connect without traditional...
Hello, I'm working with the EK PCA10003, that has the NRF51422. I'm trying to read the information of the accelerometer MPU6000 with an ISP interface. At the moment I cannot...
I'd like to use the GATT/GAP driver from an ARM based Linux system. Is there any possibility of getting a library compiled for ARM or (cough) the source code to build it myself...
It is possible to run easily a SoftDevice stack (e.g. S110) on nRF51422 using an accurate 16MHz external clock reference for HFCLK instead of an external 16 MHz crystal oscillator...
I want to change data bytes in the advertisement packet. In ACI_DEVICE_STANDBY I put: lib_aci_open_adv_pipe(1);
In ACI_EVT_CMD_RSP: I get feedback that command 1B (I assume...
I'm trying to measure a scaled down battery voltage level on an ADC pin. Given my resistor values the voltage on the pin should be about 0.279 times VBATT, to fit within 1...
Hi Nordic guys,
How much is the current consumption of the LDO only (quiescent current), without DC / DC converter, in uA? How much is dropout voltage and PSRR (ripple...
I try to modify "ble_app_ibeacon" sample code. But when I add some adv_uuids for services to advdata.uuids_complete or I changed advdata.name_type from BLE_ADVDATA_NO_NAME...
Hi,
I need to write a validation document for nRF51822 . The first step need is the specification for its calibration. But I couldn't find it in your website. Can you send...
Hello,
My project name is Remote Operated Vehicle. Basically i am using a PS2 controller as the joystick to control the car. So, my aim is to build wireless interface between...
In this function in nrf_gpio.h, why is there a GPIO_PIN_CNF_INPUT_Connect value there?
Shouldn't that be GPIO_PIN_CNF_INPUT_Disconnect, or does it not really matter?

I need to pass a bit, to 500 recipients in a closed room.
My doubt is, 500 receptors works simultaneously without interference?

I've seen various threads here with sample code attached that show how to set up a timer to measure a battery voltage periodically. They also seem to use an external crystal...
Dear Nordic Guy,I'm developing with nrf51822.
my costom code based on the hrs profile.and I modify the advertising timeout value to 30sec
and finally, I see the a few uA...
Hi,
I bought the nrf51822 chip itself, and created my own board. Now, can I still download the nRF51 SDK as per nAN-29?
I am stucked with the download page asking for...
Guys
I came over from the Arduino forums, I am searching for a new RF chip to use for a project i am working on but dont know which chip to pick. My application requires...
I want use uart to debug my ble program ,
In the devzone I found this and this to meet my need , but when I conditional compilation UART code into hex, I can not find my...
