When I decided to attempt the reprogramming of my nRF51822 Beacon Kit I read several posts related to the task. The information I needed was there but I found it to be a bit scattered. It was difficult for me to put it all together; particularly so as I am a newbie. Now that I have been successful I decided to document the process. Hopefully it will help someone. Note that several of the steps require Windows capability in order to run the tools (msi installer, crc.exe, hex2bin.exe, Keil uVision). I am a ...

I have received my Rigado BMD-200 BLE modules (nRF51822). Not only have I made a breakout board for the module, I have been preparing myself for my very first ARM development. Before I can install a bunch of toolchains on my desktop, I need one more thing figured out on the hardware front: debugger and/or programmer.I have in my arsenal a couple debugger and programmers: AVR Dragon AVR ISP USBtinyISP FTDI USB-Serial converters You can probably tell I have been hanging out at the Arduino / ATmega com...

Nordic's infocenter

The Infocenter – our new documentation portal - has now been up and running since June and contains all of our technical documentation. We saw the need for this because we wanted to make our complete library more visible, and since the documentation is now found in the one place navigation has become easier, with related content housed together under relevant topics. We’re also making content available in HTML (but, the core documentation is still available in PDF too) which means we can make minor up...

I'm currently using soft device 110 version 7.1 on a 51822.I have several characteristics that are more than 20 bytes that as a server I want a client to write to. I actually appear to have everything working. I have enabled reliable_wr. When the client writes to me I get BLE_EVT_USER_MEM_REQUEST. When presumably the user has finished writing I then get BLE_GATTS_EVT_WRITE which is then followed by BLE_EVT_USER_MEM_RELEASE. And any user the client writes I do get. I have verified that many times.The probl...

I have based my project on the SDK 6.1 ble_app_hrs. In main.c is included app_gpiote.h which I assume is for the app_button module. However in a separate class I also use nrf_gpiote.h to enable PPI shorts for PWM generation. This is based on a PWM code available on the Nordic GitHub. Could these two ever conflict? I assume they access the same lower-level code. Currently I only use them for Button pushes and (nrf_gpiote.h) PWM generation. Thanks-DC...

![image description](/attachment/1e44cbbed65dc645cc9794fc8d8cafc8)Hi there is a problem in https://github.com/NordicSemiconductor/nrf51-UART-examplesany one can help?I put empty loop in main, and comment off all ble related int. and I process uart_evt by putting debug string for APP_UART_DATA_READY: which is generated by interrupt when receives input.However, when test with one byte it works, can print "UART Debug..." when dealing with multiple bytes. the output corrupts... print "UASta›E...
