We are proud to announce that BLE DEVKIT.N R2 is back at eBay with some improvements, like a reset button, which will make development and testing even more easy.
It is coming a very interesting Bluetooth Low Energy training at London 2014 (Bluetooth Innovation Training). Major players in the field of BLE hardware like Nordicsemi and CSR will be there too.
“The Bluetooth Special Interest Group, along with co-sponsors CSR, Frontline Test Equipment, and Nordic Semiconductor have created this special one-day training to give you everything you need to get started in the exciting Bluetooth and appcessory development world.”
I think will be interesting to meet hardware and software at one place. It will be covered big part of developing process, testing and certification.
Hope to see some of you there. Namaste!
In one way I am glad to announce that we sold all available boards, in other hand we are in hurry to produce next batch of BLE DEVKIT.N R1.
In 2-3 weeks we will be ready to sell again.

I really liked the next gadget from PiFace, PiFace Display and Control.
Most of the time I use Raspberry Pi connecting to it via ssh, so no display and keyboard. It is a lot handy to have a screen and few buttons in order to interact with the Python code, you play with. So I was wondering if I can make a my own design. In the same time I wanted to be fully compatible with examples and code from PiFace. I did a research and found this article PIFace Control & Display Tear Down using the MCP23S17 (SPI I/O Expander), which was the kickstart of my next project.
Here is the result:
For embedded hardware tracing and debuting is a vital step to a stable product. Unfortunately it is not all the time a easy task. Luckily BLE DEV.N board has an option to trance and debug via serial port.

P.S. You can find the service code and sample at github .
We updated User Manual for the BLE DEV.N R2 Board with more detailed explanation about change which is needed because of the crystal we use on the board. When you try to run all Nordic Bluetooth Low Energy examples (ble_…) with our board, you need to change clock source to NRF_CLOCK_LFCLKSRC_SYNTH_250_PP in SOFTDEVICE_HANDLER_INIT macro like this SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM...
It will make initialisation of the SoftDevice to pass successfully and your example with not hang anymore.
Just uploaded sample application, which can connect to the Bluetooth SensorTag (CC2541) and display ambient and IR temperature. In order to run it is good to have Apple machine with Bluetooth 4.0 (Bluetooth Low Energy support).
