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

My end object is to connect the peripheral to one required central. It should not get connect to another central or to the nRF connect app.
I have gone through many example...
Hi everyone ,
I'm looking for the ULPMark score for the nRF52840.
On the EEMBC website, I 'm seeing that Nordic Semiconductor is a partner, but I don't find any information...
Hi,
we are late stage development on NRF52840 with sdk 15.0 and softdevice 6.0. The mind turns to certification. It all seems very complex and confusing
1) Do we need...
I have an nRF52840 based peripheral running SDK 15.3.
I have a custom service with a write characteristic and a read characteristic. The peripheral supports multiple connections...
As far as I can tell the values are inverted.

The Occupancy attribute is a bitmap.
Bit 0 specifies the sensed occupancy as follow:...
Hello
I am using nRF52 DK, I am trying to use PIN 30 as Pulse train. The following while loop is expected to send out Pulse train of 2microseconds period but instead, it...
As far I know BLE mesh uses the 3 advertisement channels for communication without any synchronization mechanisms. When the mesh protocol emits a package it will send the...
Hi
Why is Mac OS no longer listed as a supported operating system for the nRF Connect SDK (see http://developer.nordicsemi.com/nRF_Connect_SDK/doc/0.3.0/nrf/gs_ins_os.html...
Hello,
I have a question regarding BLE characteristics and bi-directional communication. Assume a service like Nordic UART Service (NUS) is used, then there are two characteristics...
Hi,
we tried the example from the NRF SDK (15.3) with the USBD_MSC. The logging looks good so far and we have a data micro USB connected to the nRF USB Plug of the dev board...
Hello All,
I have 2 evaluation boards nrf52840 EVB "PCA10056".
I would like to run on them the "ble_app_uart" in "nRF5_SDK_15.3.0_59ac345" as following:
A custom board...
I used nrf52832 to port the program from SDK14.2 to SDK15.2 and there was a problem. In SDK 15.2, the program functions normally in the online debugging state, but the function...
I like to use 2 server boards and 1 client board in mesh as custom model. Is it possible to use client to communicate with 2 or many server's without using instance in client...
Hello,
I am trying to conenct the DK to the nRF cloud. I registered the SIM successfully and then proceeded to insert the sim and power up the unit. The LED 3/4 sequence...
