Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"

Hi!
I use nrf51-pwm-library ( github.com/.../) to control brightness of LED RGB light source and it works ok till I don't want to adjust brightness slowly (dimming function...
Hello. I'm using the NUS BLE service to send ADC sensor data. I am having the SAADC callback function call ble_nus_data_send() to send raw samples. I have set the min and...
I need to measure full power consumption of nrf52, on PCA10040 from... a 5V source (because including some other 5V devices). I measure it from 5V pin and not usb plug. I...
Hi,
as I know from the mesh spec, the number of elements cannot change after a device was provisioned. Nordic even went so far as to define the number of elements during...
Hi, how to measure RSSI in OpenThread? I have 2 nodes, what is correct state that I have to assign to each node to do transmit/receive test, is it leader and router? or router...
Hello,
We're thinking of powering external sensors through GPIO pins configured as high-drive. The sensors themselves consume only a few milliamps at most, which is easily...
Hi,
I would like to control a piezo driver using GPIO pin on nRF52840 DK.
I've read posts about this kind of application. But still confused about how to set up PWM...
Hello again Nordic Pro's,
I have a mildly modiffied version of ble_app_uart_c that compiles and runs fine on an NRF52-DK board. I am now trying to use the same code on a...

Hello,
I am facing a issue with the LN service. I am notifying the position at 10Hz and this work well. I have implemented a custom service that allows to send a file by...
Hi,
Just as the title says, I want to use nRF52840 as a peripheral(s140, v7.0.1, BLE_NUS_MAX_DATA_LEN is 244) and using NUS.
And it may pair to a nRF51822(s120, BLE_NUS_MAX_DATA_LEN...
Dear
I got a problem about SES when I create a indepent transferable project for PCA10059.
