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...
Hello
I'm using nrf51822 EK board. This is my first time to develop application in ARM system.
I want to develop a ble application.
This application can be shut down (system...
I've got my custom PCB design assembled. Attached segger jlink, but it detects only 0.1 V, although Vdd is 3V.
How is the power measured?
What should I read on SWDIO...
Dear
Is there a possibility within Nordic SoC to make a passive RFID Tag which will connect to SmartPhone via Bluetooth?
Just like µBlue Series, but smaller and using...
I found the "S110_SoftDevice_Specification_v1.2.pdf" but not the "S110 softdevice release notes" mentioned in a previous question about DCDC usage. Where is that doc?
What...
I have been developing on a nrF51422 QFAAC0 chipset. That chipset required SDK 4.4 for soft device capability.
I requested the latest silicon (so I could develop against...
Hello,
I would like to build a tool in Python that allows sniffing/interaction with BLE traffic between nRFgo modules (nRF51822) and a Mac via the master emulator. I am...
I have bought the Bluetooth low energy evaluation kit nRF51822. It can be paired with a Nexus and a Sony Xperia without problems, but it does not appear at all on Samsung...
L.S.
Today I decided to have a look at SDK5.1.0 for nRF51822 which supports the S120.
It is deliverd as an msi file with (as far as I have noticed) no support for specifying...
Is there anything preventing anyone from uploading the tinyest image that simply dumps the entire ROM content on the UART?
This would sort of circumvent the HW locking...
Hello,
I use nRF51822 for my project and I would like to purchase some BLE packet sniffer. Does anyone recommend any sniffer? My purpose for that is debugging and check transaction...
On PCB layouts I often see that the HF xtal is oriented at 45 degrees relative to the orientation of the 51x chip (that is to say the edges of the the xtal and 51x chips are...
Hello Nordic expert,
Regarding the antenna load impedance, I can find the data in nRF24L01+ datasheet and it is 15ohm +j88ohm.
But I can not find the antenna load impedance...
hi,
now ,i have save the power,so need to close the spi interface at some time.
but when i call follow function (hal_spi_disable).
it see not close the spi interface, ...
Hello,
During programming bootloader provided with sdk
I get some messages in Command window in Keil.

Since I'm writing code for my own board, I decided to create my own board.h file to hold the board-specific definitions.
However, I can't do this without hacking the SDK...
