Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi, I am trying to test my UART using some simple loopback test, and I have noticed that the service discovery command of BLE will occupy the CPU a quite long time. I am just...
I was unaware that the 'manufacturer data' in the advertising packets is limited to less than a full payload. However, whenever I set it to >6 the program "crashes".
...
When I use keil to download the software to the chip, there are two questions:
like attached.
2.NRFGO CAN'T SEE J-LINK LITE CORTEXM BOARD
Is there any way to solve...
We have recently moved to a new PCB which puts the nRF8001 on the layout instead of plugging into a nRF2741 development module. The nRF8001 connects to a TI Cortex-M4 Tiva...
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm...
To be more detailed:
One of my ADC pins will be connected to another device that could be providing a voltage of about 3V, but through a 100 kohm resistor. (actually it...
Dear Nordic Developer Zone,
Since I have implemented a timer with interrupt in my application, the debug mode if the Keil IDE stops working when I try to restart the code...
Hello, I'm trying to develop with the nRF51822 Eval kit and GCC and Eclipse. I've been getting some strange behavior and errors lately. I'm not really sure how to describe...
I'm a green hand HW Engineer.
I'm trying to compile, program, and run The Heart rate monitor demo though following the step in nRF51822_DK_User_Guide_v1.0.pdf .
First...
Hi Nordic devzone,
For the nRF51822 device, I would like to know if there is any internal pull-up/pulldown resistor on SWDIO and on SWDCLK (although a 12 K-ohm pulldown...
Is it possible through the API/Softdevice to do one of the following:
read out the current advertising data structure, change a the manufacturing data field, and...
Hi,
I am planning to use modules with nRF8002 in an indoor positioning application.
The mobile devices that are to be located are continuously scanning for BLE devices and...
Hi, got an interesting problem, this is on a custom board with nRF51822 QFAB that we are bringing up. The radio test (not using softdevice) works ok and produces strong transmit...
Hi
Could you provide the power current in System on Active, System on Sleep, and System OFF for nRFready Desktop2 keyboard and mouse? nRF51 was programmed Desktop 2 v1.0...
