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"
to develop a new project, and encounter some questions...
we update nRF6310...
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,
We designed an antenna for our new product and we would like to have your feedback on it before making the prototypes. Below is the design
The dxf file...
Hello everyone! I'm new to bluetooth mesh or even to C programming and i don't understand the following: I want to send messages over Bluetooth Mesh from an nRF52840 to another...
I tried to install the CDC driver using nordic_cdc_acm.inf in the DSK15/examples/usb_drivers directory but the installation does not work and I get an error message when selecting...
Hi,
I tried several examples on nrf52840 dongle. Each one works well except usbd example. It hangs at the following code:
After investigation, the following simple...
Hi to all,
i am developing a device with nrf51822 and i want use it as a peripheral device, i want to write 4 packet per connection interval on noti char. i am ok with one...
Dear Nordic,
I just started with nrf52840 DK and my custom board. I derived my custom_board.h from nRF5_SDK_15.0.0_a53641a/components/boards/pca10056.h. I need to reroute...

Hello,
we want to evaluate the nRF52832 chip with a example project. This project has the following functions:
- low power
- system wakeup by RTC running with external...
Hello,
I do want to simulate the behaviour of several nrf51 chipsets that communicate over the air. Do you have any suggestion, how to start with this? The best would be...
Hello everyone! I am interested in running some simulations to test a series of algorithms for BLE on nrf52832. Is there any simulator which can easily simulate nrf52832?...
Hi All,
This may not be 100% nRF-related, but:
I have a set of algorithms that are written with Keil uVision 5 for nRF52840 using the CMSIS-DSP library. Now, I would need...
