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,
For our current application we have migrated from SDK 13 to SDK 14. We are using RTOS to handle the functionalities of our application. We replaced our own task for handling...
(nRF51822, but also concerned with nRF52832, SD130, SDK 12.1)
I'm trying to write/erase flash from a bluetooth event handler. As it's been outlined in other questions,...
Hi,
I am just updating my application from SDK13.0.0 to SDK14.0.0.
2 Services are in use: DIS and NUS. To advertise that, I made use of the scan response functionality...
Hi,
I have the D52QD2M4IA-A chip (from dynastream) that has inside nrf52832 chip. It has also builtin an onboard LIS2DH accelerometer. However when I am trying to connect...
Hi,
I am working on nrf52832. I am preparing application where I need to handle central connection with two peripherals and keep tracking time. I know that softdevice has...
The data sheet recommends that both the TWI clock and data lines use pull ups and the GPIOs should be set to S0D1, essentially open collector drive. I can see the need for...
When trying to follow this guide for testing bluetooth mesh on a nRF51 dev-board Cmake returns this error:

Hello, I have had luck in Keil making two NRF52 connect with NUS, central and peripheral. My goal is to have one central speak to multiple peripheral at same time via a piconet...
Hi
I have just baught some nRF52840 DK boards,
and I can test the BLE throught between those nRF52840 DK boards successfully.
This indeed help us a lot about research...
Hi,
I am using SDK 12.2.0 with my custom board. As per the my requirement, i need to ground or set logic 0 of my gpio pin no. 12.
So, how can i do this?
good morning to all
I wanted to ask if anyone has a design of nrf51822 where an external temperature sensor is used, to know how the connection to the chip is. Should I buy...
