Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

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...
Hi
I have firmware uing SDK 7.1 and SoftDevice 110. There is prepared bootloader for DFU, and update by very old nrfToolbox app works fine. But now I want to update this...
Using the Data Length Extension (DLE) feature in BLE v4.2, two nRF52 dev boards can achieve a maximum throughput of almost 800 kbps. I tested DLE with an iPhone 6 and the...
I am new to nRF ICs.
How to get 32.678KHz clock out from a pin? Is it possible? If yes, from which pin and how to configure it?
I am using 32.768KHZ external crystal fro...
I have designed several boards for the nRF51822-QFAA, namely with/for the Waveshare Core51822 module.
While one is working as expected - namely my "Orchid Lamp" (see links...
When softdevice S110 is used then bonding is not occuring (via nrf connect app to nrf51).but both devices get bonded when s130 is used?In Nrf connect app key matching failed...
Hi,
I have a working project where I use PWM driver with LEDs on the development board. I make use of the d52_starterkit.h where I have the following definitions:

Hi,
On a system reset, we want a mechanism to stay in bootloader for a short period before jumping in application. This way, if something is wrong in application that prevent...
Hi,
I am using ESB library for nRF52 microcontroller. At receiver i want to measure RSSI value of a packet. I got RRSI from nrf_esb_payload_t structure.
I am printing...

Hi,
In my project i would like to save 100 bytes of information in RAM before going to System-off sleep mode.I have tested the example project given in sdk11 works okay.Have...
I am trying to read the battery level on a custom NRF52 board and I am getting a value that is around half of real voltage.
The same code works fine on NRF52 DK ( I was expecting...
I am looking at this example: github.com/.../main.c
In ble_evt_dispatch (line 315), this function forwards an BLE event to all of the modules. By looking at ble_evt_t,...
