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'm running into an issue in which I cannot initialized the I2C drivers on an Arduino Nano 33 BLE (nrf52840). The output from error logging is

Hi. I am using timers and PPI to do frequency counting.
The basic process is for 1 PPI channel to incriment a timer, and then a second PPI on a second timer to stop the...
I build device based on Fanstel module BC833M with pcb antenna.
Communication with this device is very bad. I have test the same code in BC833M and origin Nordic devkit...
Hi,
First off, I'm very new to the nRF52 development so I'm suspecting to have done something wrong...
The datasheet of the nRF52 832 states a current consumption of 0...
Hi,
I have been tryring to identify the characteristic who is requesting a read. To do so, I implemented the read authorization request. Here is my code:
Basically...
Hello,
I'm trying to receive an inverted UART signal on the Arduino Nano 33 BLE (NRF52840). I've been able to invert the transmit signal okay using two GPIOTE channels and...
in ble send data period ,nrf 5340 CPU seem to be shared only by ble send
data ready and data read in ble not send period can equal ,this mean every data come from ecg chip...
Excuse me:
I'm testing the maximum rate of ble_app_uart。
1、Can the nrf connect app on IOS initiate the update of MTU and PHY?How to update MTU and PHY on IOS nrf connect...
I use nordic5340 SPI read ADS1298R ecg data, using nrf5340 p0.13 to connect ADS1298R data ready pin . when ADS1298R data ready pin high to low mean ADS1298R data ready .i...
Hi guys I am new to Nordic, just made a DevZone as the technology isvery interesting to me. So far I have been playing with ESP series but I know nordic is in a class of its...
Hello everyone,
I have been working for a few days with nRF52833DK building a BLE mesh where one of these microcontrollers is a client node or a server node.
However,...
Hi,
I have several questions about the dongle board.
1. Why should the p0.19,20,..,25 be connected to the reset pin?
2. what is the difference between the reset button...
