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...

Hi there,
How in the question title, what could be more efficient? use a nrf_delay_us or Timer with HFCLK source.
I am creating a custom protocol to transfer data between...
Hi, is it now possible to flash (via DFU OTA) a nRF51X without the nRF Dongle, but with a generic BLE dongle on Windows 10 ? Thank you for your answers.
Hello,
I am using Nordic's iOS library to perform DFU in our app to upgrade firmware on some BLE devices. Before the DFU, the app scans it as "Paradevice", but reads it as...
Hi,
I'm designing a prototype board with the nRF52832-CIAA and was planning on using the Johanson 2450FM07A0035T integrated 2.4 GHz filter, but have not been able to find...
Hi
in pcb designing of the nrf52832 we use two oscillators one is 32 MHz and another one is 32 kHz.
can't we use both 32 kHz instead of one 32 MHz for saving power consumption...
Hi,
I can't seem to find an example for receiving an update about restored value of CCCD when a bonded peer reconnects. I'm using SDK14.

Hi,
I am beginner for nRF52840. I use Keil uVision 5.20 to develop firmware. I have a problem with the Nordic packs downloaded from Keil website. The USB driver is not take...
Hello.
Until now, we work with NRF52832 for a new product but we have identified that the memory (64kB of RAM and 512kB of flash) of the chip will not sufficient for our...
