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
Firt I connect to Android device and keep one whitelist.pp_addrs and one whitelist...
It's my question. I use saadc single mode from nrf52832 to sample voltage .When the original voltage is 24 V ,measurement of the pin is 2.8v,I set the resolution to 10 BITS...
hi,dear engineers,
i use the example experimental_ble_app_buttonless_dfu of nRF5_SDK_13.0.0_04a0bfd,
on the PCA10040 board,Now,i'm sure that I am flashed Softdevice,app...
hi
I have designed a small PCB with the NRF52 chip on it and kept few ports for some peripherals. Apart from that I only have 4 pins that I can connect to, UART-Tx, UART...
Hello,
I'm wondering if my nRF DK51 is not broken as it behaves quite strange when trying to connect with a BLE Central (iOS and Android devices). For most of the part...
I am trying to track down a power usage problem with my code. When I started using SDK 13.0.0/S140 v5.0.0-2.alpha on a PCA10056, the power usage went up in my app. I see that...
I'll try to simplify my project as much as possible to make this understandable.
I'm wiring an nRF52 PCA10040 board to an iCE5LP (Lattice) FPGA.
I'm having an issue with...
I have an after market breakout board for nrf51822 with a usb-to-serial chip (cp2102) that I bought from Amazon . It should act as an NRF51 USB dongle (pca10031-like) but...
My pc server should send information to nrf52832 by ECDH, then I create a dll file from micro-ecc. However,the result in windows is not the same as the result in nrf52832...
dear friends ,
within a peripheral connection event, 9 states is identified, as it is shown in the pic above(from s132 document). Can i get a detailed description about what...
Hi @ all,
I am working with IoT SDK 0.9 and nRF52DK.
I have trouble with the lwIP CoAP client example.
Everything works so far, the board is connected and I'm able...
Hello! I am using a custom board that contains a nRF52832 device. The board has the SWDIO and SWDCK lines connected, which I have successfully been using to flash and debug...
I'm migrating to the new 13.0.0 SDK and I'm wondering what are the benefits of using nrf_serial over app_uart (if any) and what steps I would need to take to switch over if...
I have successfully manged to achieve serial communication between my PC (Windows) and nRF52 board by using the pc-ble-library and the pc-ble-library-js .
I can run without...
