We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
Hi,
I am trying out the FOTA feature on the nrf52840 dongle. I managed to build the SMP server example and flash it using mcugr. However when i reset the device, i can't...
We are evaluating nRF52832 for our next product. One of the requirement for us is to interface 3 set of sensors with nRF52832 over I2C.
Because our sensors can't share the...
Hello, I'm modifying the ble_peripheral/ble_app_hids_keyboard example on a custom board. When I pair my board with the first phone, it works fine.
But I can pair it with...
Hello, I would like to implement an acceleration interrupt in the asset-tracker2 program (SDK v1.7.1) that is executed immediately on movement. This should be executed in...
Dear, I defined Port1 pins as in attached overlay file. The binding of pins is done as in lcd.h attached file. When, build is started, the error written in title is displayed...
Hi,
for a last year I was developing any apps for nrf52840 in Keil IDE. Now I'd like to migrate my projects to VSCode but still do not understand some curcumstancies:

Hello,
We have designed a product with NPM1100. With the NPM1100 set to output voltage of 3.0, we have measured the output across multiple devices to be in the 3.1 to 3...
Hello everyone , I am interfacing and trying to process GPS data received over UART port. The GPS outputs NMEA based sentences at a rate of 10 Hz. I started using the example...
I've tested two scenarios using a hardware loopback to test UART functionality. The double buffer approach does not work as expected.

Hi,
I used nRF91DK for almost 2 months non stop to debug the final nRF91 based board for our air quality monitoring hardware to fight the propagation of Covid virus.
But...
I tested various copy methods in terms of instruction cycles, that I determined with DWT.
For that I copied an uint8_t array size 70 by
