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

Greetings. Could you provide more information on the issues with GPIO located near the radio in the nRF52 (PS 18.2.1)? Specifically, what is considered "high frequency digital...
I've created a BLE Peripheral project to test maximum possible throughput for the Notify of a single characteristic. I've also created a Central based on the new BLE Central...
Hi: I want use all eight ADC channel, But I don't know how to get different channel conversion result.
I write my code as follow:

Hi,
I'm using the 3rd generation of nRF51822 with S110 v8.0.0 and the SDK 10.0.
In my application i'm using the uart core to communicate with the external device.
I'm...
I'm not sure why I didn't notice this sooner.
When trying to do a bonded DFU with a Nexus 6P and Master Control Panel it seems to get stuck in a loop reconnecting.

Hi I trying to connect Altimeter ( mpl 3115a2) to the nrf52 development kit. Can someone guide me how to do it (pin connection). I have followed the example given in the sdk...
I received my nRF51 DK (with nRF51422, PCA 10028) and I could successfully run the S130 demo app thats included with SDK 8.0.0.
The above demo demonstrates for e.g. :

I was upset early this afternoon because I was experiencing issues with buttonless DFU on Android. As is usually the case, I assumed it was my fault.
First, I reverted...
Hi Nordic--
Our custom nRF51822 design has 13 signals routed into the app_buttons module through the GPIO -> GPIOTE->PORT -> nrf_drv_gpiote.c -> app_buttons.c path. For...
Hi,
I have a problem to program an external board with my PCA10028 board. My external board is a Xuntong chip.
( Heart-Rate-Monitor-2-4GHz-SOC-BLE-Module-based-on-nRF51822...
I'm trying to measure absolute minimum power consumption of the chip using the PCA10028. I cut SB 9, and applied a very sensitive current measuring device to P22. I'm running...
Hi all,
I am having ADXL335 Acellarometer board. Here its giving data of X,Y and Z axis directly in analog form.
So how should i configure my IO pins of PCA10001 board...
