Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...
hts, HTC phone, nrf tools HTM, nrf51822,
every time when it's power up :

Our company needs wireless temperature sensors (can be externally powered or battery operated) and transceiver with 4 channel analog outputs. It has to be finished product...
Hello-
I am trying to program a custom nRF51822 board with a J-Link-lite.
From the J-Link-lite, I am using the 10-pin header and have it wired like this:
I'm using pins...
I have a situation where I need a software PWM for several channels, which are multiplexed via a shift register.
The output loop needs to run at several kHz for this to...
Because of the limitation in the GPIOTE hardware that only one channel can be connected per GPIO , care must be taken when changing a PWM duty cycle. If for instance the compare...

Hi Nordic
I do not know why sometimes program can build pass in keil ,but can make nrf51822 do not work and unable download program . For this , I have damaged a lot of...
Does the nrf51822 support 2 spi masters (on different pins)? I want 1 spi channel to talk to one set of peripherals, and the other to talk to another set. I see SPI_MASTER1_ENABLE...
Maybe question similar to this one devzone.nordicsemi.com/.../
Can I use the interrupt generated by RADIO_IRQHandler(void) while implementing another protocol?
At the...
Hi everyone,
for our current project we have to implement some sort of activation lock. Therefore, we would like to use the MITM security mechanism of BLE. The idea is...
I have an nrf51822-mkit.
Let's say there are 2 BLE phones continuously searching for my module. Phone 1 connects and communicates with the module. The modules determines...
I used the ble_app_lbs example as a template, with a PCA10003 eval board (nrf51422 chip). SD 110, Nordic SDK V6.1. Keil uVision 5.
I launch my application and my board...
Hi,
In softDevice S120 can we make second sd_ble_gap_connect on different peer, without waiting confirmation connect of the first one ?

Hi
NRF51822 with SD7, S110.
I have some troubles with DFU procedure. I uploaded standard OTA-DFU bootloader and S110 to my NRF. Everything works well with my code except...
Hi,
I was wondering if it is some easy way to turn off that the system goes into system off mode after a while for ble_app_pwr_profiling?
I would also like to test it...
hello everyone,
we're currently working with some nrf51822 beacons and throughout the project we recorded the antenna patterns of several of them. In the first batch we tested...
