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...
Hello everyone,
I got a task which I try to implement using a NRF51822 iBeacon board.
The Task:
Advertise a Device and provide a mechanism to connect without traditional...
I want to log basic intermittent events and push them to a previously associated mobile device when one is nearby. The mobile device can then forward the events up to a server...
I'd like to know what is the minimum and maximum frequency I can generate on a GPIO with a 50% duty cycle (+/-10% at the worst case). Which resources should I use for that...
In my case active CE signal defines byte boundaries - for each byte individually.
From what I see, DMA seems to stop on rising edge of CS regardless what is declared in...
Hello everyone,
I'm using nRF51822 development kit to do BLE network experiment.
The boards I use are PCA10005 with omnidirectional antenna, and PCA10004 with PCB antenna...
I'm looking at the UICR hardware peripheral example , and trying to figure out the utility in writing to the UICR registers.
Why would I want to modify the compiled hex...
Very new, so please forgive the questions, but...
I have an nrf8001 that I've powered up. After initial power up, I'm able to read the DeviceStartedEvent but the response...
I'm looking to integrate a digital (PDM/I2S) MEMS microphone into my nRF51822-based design. I'd like some pointers to reference designs or other information -- the ones that...
Hi,
I would to know why when the DC/DC is enabled the current is very high (57mA) during RF sending.
Why at the end of RF sending the current is higher than...
I am modifying the bootloader. I am not using DFU or any of that, but rather copying a FW image over from external flash through SPI. The area of my code that gives me problems...
The documentation of the S110 contains sequence charts that explain how the different GATT operations are performed.

Hi,
I've been trying to do fake non-connectable advertising with a nRF24LE1 with base on [1] and [2], they use nRF24L01+ with an AVR which I have ported to my device. I...
Hey,
I'm evaluating a nRF51-DK and face NRF_ERROR_INVALID_ADDR when trying to set a value in the local gatt server database.
My goal is to create a read-only characteristic...
Hi,
I'm using nRF51822 Beacon v1.1.0. Is it possible to detect that the beacon is being scanned? Is there any event generated during this process that I can catch?
I have been studying the ble_app_hrs example, but it has unnecessary functionalities, and it is hard to understand.
Do you have a simple application for transferring data...
