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'm using the SAADC of an nRF52832. I'd like to reduce the error of my measurements from the nominal +/-3%. I'm calling the NRF_SAADC_TASK_CALIBRATEOFFSET periodically to...
Hi,
I am trying to use nrfutil to generate my verification key.
However in the bootloader the key has this format
__ALIGN(4) const uint8_t pk[64] =

Hello,
I am trying to update my bootloader using DFU and I am running into a few issues. I have successfully flashed and tested my current bootloader on my board and everything...
I am using the nRF51822 in an application where I want to run the UART as fast as possible to communicate with a host processor. I have been able to get reliable communication...
I am trying to create a package file to use with the DFU on my design.
I followed the instructions for getting nrfutil latest version built and was able to generate a private...
I'm using an NRF8001 with an ATMEL ATMEGA 328P (the microcontroller from an Arduino). I need the microcontroller to go to sleep, but still allow the BLE chip to advertise...
Hi,
for development i am using gcc and makefile on osx.
I wanted to automate my makefile with the possibility to upload directly the hex file to my nrf52 devboard.

I'm using PPI to trigger a gpio high after a given delay from 4.00 ms to 8.00 ms. I need to be accurate up to .01 ms but i'm seeing some jitter in the actual delay vs given...
Hi,

Hi
I need to develop PC software to Discover, Connect, Get and Set data to the nrf device that we developed.
I am using the MCP and nrf connect but my client want to...
Hi,
I'm actually working on BLE product, with NRF52832, where security is really important. As I know BLE 4.0, 4.1 versions are not really secure with the key pairing ...
I see that Nordic was a Bluetooth SIG contributor to the Continuous Glucose Monitoring Service (CGMS) and that it was adopted on Nov 18, 2014. We have an immediate need for...
