Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
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...
Are there any specs available regarding the performance of the nRF52 ADC's internal voltage reference? Accuracy (%) and temperature drift (ppm/degC) would be good. I couldn...
Hello,
I'm developing proprietary radio protocol using nRF52 (not using softdevice) and would like to know if it is allowed to write NRF_RADIO->FREQUENCY register while...
Hello, I've got a problem with an app_timer
starting from the BLE_UART example, I've set
#define APP_TIMER_PRESCALER 4

Hi Nordic,
when 51822 communicate with an app,is the best way to use different services and characters
to achieve different passageway or use a self expand protocol on...
dear all
I have two same 51 822 device with same program, one is normal, the other can't be connected even re-power manually .The two all can be found by nrf master control...
Hi,
I have been able to use SAADC to measure temperature, but my code does not behave in the way I expect it to!
In the config file I have the following settings set:...
Good day,
I try to add inline assembler like this:
asm("POP {R12,PC}");
but I have an error:

Hi!
I'm currently developing a driver to communicate with a sensor via I2C using the Nordic's nrf_drv_twi library. I based my code on the twi_sensor example, but since...
