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...

Hello,I found in S120 documentation that minimum connection interval for 8 peripheral connected to central must to have minimum connection interval 20 ms.But what is the minimum connection interval for 4 peripheral?It is posible that 4 peripheral send data at 4 kbytes/second and central to receive all at the same time withowt lose the packet?In datasheet write that data rate is 4 kbyte/second,but I don't understand if 4 kbytes from all peripheral or from each peripheral?Thanks in advance!...

https://github.com/NordicSemiconductor/nrf51-UART-examplesHey any I was trying to test the example, the one with BLEI test APP BLE sending --------shows on PC UART softwareHowever, I can not make PC UART software ----->>BLE APP workI suspect sth wrong with the void UART0_IRQHandler(void),so, I put global variable inside, to debugit seems that when sending 1 byte, the interrupt functions. when sending multiple bytes together ,it restarts the main.I dont quite understand the function as the comments:*...

good work.I will have a question for you .I think to make the connection and the connection I made adxl345 nrf51822 and LCD screen x, y and z coordinates , I want to show .Can you help me in this regard...
