we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...

I am trying to measure the power consumption of a PCA10040 board while debugging, using the PPK. I am using the setup shown here: "Measuring current on nRF5 DK while debugging...
Hey,
I found that sdk 12.3.0 (the latest for nrf51822) has example fpu_fft with linked CMSIS_DSP lib, but this lib is for cortex m4. I downloaded arm_cortexM0l_math.lib...
I have a problem getting fstorage to work with BLE in SDK 14.2.0.
The fstorage example works fine until i change
NRF_SDH_BLE_PERIPHERAL_LINK_COUNT to more than 0

Im am running a nrf528322 board with the s332 softdevice using sdk14.2.
I have implemented flash storage in my program according to the nordic flash_fds example. This works...
Hi Nordic,
I am using SDK 12.3.0 and S130 2.0.1. I have some questions about AFH.
1. Do Nordic stack keep track of some bad channels during communication and would skip...
Hi I am working on pcb design for a long range application with nRF52832. There are lc circuit which is implemented to antenna pins on reference design of nrf52832. I decided...
Hello,
I am trying to develop a custom BLE service. I have been following this tutorial .
I have also looked at this answer to understand the signal path for a WRITE event...
Hi!
I'm using SDK13 (Softdevice version 4.0.2) and I noticed that during an update via DFU bootloader the update of the Softdevice doesn't work.
After the transmission...
Hi Everyone
I have been trying to use nrf52840 on a custom PCB . So far everything is working perfectly except only one single issue which is the controller gets reset and...
I'm new to the NRF series, and for that matter Keil. I have a BT832A which is apparently an NRF52810.
I am able to flash my own code using Keil and and control GPIOs to...
Hello, I am battling with weird problem for 2 days already, need little help if possible, I have tried all remedies and nothing worked so far.
Here is what happened, I followed...
Hello,
I am using SDK5 for my code that builds successfully under Linux, but not under windows.
The error occurs in the SDK, not in the application. I am wondering what...
Hi,
We are trying to optimize the speed at which we send data over BLE UART with the nrf52832. Currently, we are using the ble_nus_data_send() function in a while loop with...
Hi, I am a beginner at this and I want to make a scroll wheel that connect to Android devices as an HID device. I have a custom BLE board from Skylabs (SKB569) with NRF52832...
