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...

We love the radio range of the Nordic bluetooth chips. I am looking to see if anyone is developing a long-range bluetooth pendant or wearable? if so, I interested in perhaps...
The NFC example (launch app) on SDK12 does work on my device. However, when I copy exactly the same code into my own project, the NFC does not work. The difference is that...
Hi,
We search some technical informations about Low Power mode PWM. What is the Max Frequency ?
What is the current consommation ?
Someone knows these informations or...
I'm attempting to use a GPIO configured as no-pull to determine if a 5V line is connected to the board for charging a battery. I have the 5V line going to a GPIO through a...
I'm having no success getting the FDS (Flash storage) to work on my nRF52 PCA10040 board with SD130 2.0.0 and SDK11. I am using the Nordic example on Github here: github.com...
i am confused how to build a nrf52832 demo that use mbed os and other mbed things.
and i tried link text download the demo from github, but do not know how to put in it in...
Hi All,
I have enabled the UART service in my beacon application.I Configured write access and write permission to characteristic UUID. I got connected to the device and...
Hi!
I am new to the embedded world and am trying to interface a NRF52 DK with a MPU 6050 accelerator/gyroscope. Right now, I have been able to interface the MPU 6050 with...
file.txt Hi,
In my application I am using UART service which receives the data sent from APP. I am using nrf connect APP. I am sending simply 1 and 2 from UART service...
Hi.
I develop an application in the past with ARDUINO and a nRF24AP2 module with great success. I can read 8 heart rate monitors ANT+ sensors in the same time, with 8 differents...
I am a newbie in embedded programming. I want to encrypt some advertising data using aes-ecb API, provided by the softdevice but I am not getting any encrypted data after...
Hi,
We are currently using SDK 10 experimental boot loader example. We would like to encrypt the firmware before creating the zip file for OTA. The procedure we followed...
Hello everyone,
I am trying to use BLE module on nRF51 in central (oberserver) mode using IOT Softdevice. I want to scan for any device around my board.
I get error when...
I'm trying to read 8 adc channels using SPI, but then if I dont put some nrf_delay_ms the MISO return nothing and the CS is being driven low by default, high or a period of...
Hello All,
