Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"

Hello,
How many RX buffers are in S110 SoftDevice? I know there are 6 TX buffers (so you can send 6 packets per Connection Interval).
How is it on receiving?
Is it e...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
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...
We are in process of identifying the right hardware for our project and considering nrf52832 as the core processor. For our requirements, we need to use external serial NOR...
