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...
I have been struggling to reduce the current on the Nordic Dongle to the sub 3 uA levels that the specs suggest I should be able to achieve.
I am stuck at achieving a 9...
i am trying to determine the current consumption of the nRF9160 when in sleep mode but running LPUART and TWIS.
I see that the Sleep mode (MCU IDLE, MODEM off, RTC on) shows...
Hi all, i want to use CMSIS DSP library for vector/matrix computation.
In NRF connect SDK, there is a "nRF CMSIS DSP examples solution" in the dashboard, however it fails...
Hello,
I have an external flash w25n01gv, I am using this simple spi loopback example to test the spi functionality of nrf9160. I want to read the jedec id of my device...
Does doing DFU again and again on same controller can cause misbehavior of code? I am using BLE + UART + EEPROM in my code and sometimes I face the issue with UART event handler...
Hi,
I'm using NRF52840 to connect my mobile.
I'm using whitelist, following the example. It used to work perfectly for about 1 year.
However - in the last couple...
After starting the program, I do the first calibration and read the data 30 times. The standard deviation is between 2.0 and 2.3. Perform 30 "Calibration -> Read Data" each...
Hi,
Greetings of the day!
I used nRF Connect for desktop to program the nRF52840 device. But I can't lock the program and protect the device using this utility. I installed...
Hi,
I tried controlling the LEDs connected to P0.0, P0.7 & P0.11 by using
nrf_gpio_cfg_output(); nrf_gpio_pin_set();
nrf_gpio_pin_clear();
& ble_app_blinky example...
Hello,

Hello,
I am tested multi-channel BLE peripheral connections. (ble_app_uart example with saadc example.)
When I am testing 2-channel, it works well.
However, when I am...
