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...

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...
Hi
We are developing software for the nRF51 with Keil under VirtualBox. Previously we used the PCA10000 dongle with the Master Emulator and MCP without issue. Now, with...
It seems like there are several asynchronous things that happen and it's unclear what had proprioty over each other. I assume interrupts asynchronously interrupt everything...
Hi,
I use the nrf52 dk(PCA10040). When monitoring the current consumption of the advertising with the DCDC enabled, we see some current spikes. Why?
Here is two screenshot...
I modified the code of ant_background_scanning_s212_pca10040 to make it works with s310 on nRF5144 xxaa.
The code works fine, but loose a lot of RX packets (more than 80...
Bluetooth device directional broadcast (set my mobile phone Bluetooth device address), I open the phone Bluetooth, will automatically link if you can not automatically connect...
Hi,
The samples for using list are BUFFER = 4, but it does not specify is that is the only size that works, and what value do you place on NRF_SPIM0->TXD.LIST
In my...
Here is a little background.
I have been developing a product based on the S130. I used the device manager from the S120 device since version 0.9 alpha. I was able to build...
Is there a mechanism to notify the application when a client reads from an attribute? For example, I have a large attribute buffer (100 bytes max) with a default MTU size...
Hi,
We are implementing a device where we need to use BLE and PWM. For generating PWM we use app_pwm library. To decide on the number of cycles of PWM pulses, we use a separate...
Hi,
Is there a way to power only the nrf52832 on the development kit(PCA10040)?
Background: We would like to test a solar power source but we don't want to power the...
Thank you very much in advance for any help.
I am attempting to upload an example firmware on a nRF52832 with the s132 softdevice BLE stack and the example DFU bootloader...
just like
github.com/.../nrf52-mpu-easydma-using-timers-and-drivers
we add a sensor, and try to read 2 sensors by 3 command in i2c.
is it possible to still using ppi...
Hi Friends,
I am beginner for nRF51822 and I install uVision 5.20 to create program for this chip.I can't see this chip on device selection table when new project creating...
Hi,
I've recently bricked my nrF51822 Beacon Kit ( www.nordicsemi.com/.../nRF51822-Bluetooth-Smart-Beacon-Kit)
...by uploading some bad firmware. I can no longer program...
I am beginner for nRF51822.I installed uVision 5.20 to program nRF51822 chip.I could not see nRF51822 chip on chip selection guide of uVision software.Also I need some example...
