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 try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

Am trying to evaluate the nRF9160 + nRF52840 combo as in the thingy, we want to send an sms to the device and reveice back its GPS location. SMS is spectically requested for...
Hello,
I want to prevent a scenario where I successfully perform a DFU with a faulty firmware image. I have a bootloader that handles firmware updates both for the NRF5...
Hello all,
I am working on low power sensor development with nRF52833 as target. I have some questions but I'm not sure it this was addressed in some other posts.
1. I...
Hi,
I'm integrating some c++ code using ble_app_uart example as base. The code has some cout << "text"; kind of outputs that seem to go to uart by default configuration...
Hi. I'm trying to find out the real consuption of the nrf52832. I have two questions after consulting part "7.2.1 CPU performance" of the datasheet.
1- Is there a difference...
Hello,
I have recently used the new toolchain manager to upgrade to ncs v1.3.0. Now I am using Segger Embedded Studio to flash an nRF9160 with the at_client sample. My issue...
Hi ,
I have an Android app that acts as a Central mode and Nordic nRF9160 as peripheral mode.
Once the connection is established , App will read the characteristics...
Dear all,
Pushing the hardware to the limits, I came up with a question about the architecture of the microcontroller itself: Can two different instances of SPIM start...
Hello,
I am experiencing some strange behaviour through DFU process when build with GCC -O2 optimisation.
The upgrade process seems to complete successfully but after...
I got a device with a secure bootloader, but I lost the private key and the firmware got corrupted somehow. Is it possible to flash a new bootloader via BLE or is it bricked...
I am trying to understand the following, hopefully someone can explain:
AFAIK, BLE advertising is stopped as soon as the limit of the SD is reached, AKA the PERIPHERAL_LINK_COUNT...
Hello, I am I'm a novice at developing NRF 51822. My Development Environment sdk : 12.3 IDE: KEIL v5 SoftDevices : s130
It's being developed in this environment. Q1 .NRF...
Hi. I am struggling to build the DFU secure bootloader example for the n52 DK development kit. Using SEGGER embedded studio.
I get the following error;

Hi Support Team,
We bought the nRF52 DK along with the PPK so we can measure current consumption of a DUT. It was working on the power profiler App in nRF Connect and we...
