Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hi,
For our current application we have migrated from SDK 13 to SDK 14. We are using RTOS to handle the functionalities of our application. We replaced our own task for handling...

Hallo everyone!
I need very low consumption when BLE working. according to S110 SDS, BLE power profile section, when BLE in idle-connect, there is Ion+Irtc+Ix32k, same...
Use the spi_master_example_with_spi_slave in SDK6 to evaluate the SPI master module but fail.
No matter use the default pin assignment or re-assign, it does not give out...
I can't find in the documentation for the IoT the usual section about requirements for the start of user code, the start of user RAM, the max stack used and whether any heap...
I would like to be able to generate DTMF tones using PWM. I am very familiar with the process, having written code to do this several times on other devices. The DTMF will...
Is it possible to use the nrf51 dongle with raspberry pi b+ ? I'm prototyping a 6LoWPAN solution where the peripheral nodes are nrf51 devices. I'd prefer the central device...
Hi, I'm not used to the bsp.c so my question could be silly. I hope you could understand.
When I used SDK 6.1, the example about button_event_handler function had a parameter...
What is the best way to transfer an array of individual values using the BLE stack?
Is it by appending all the values into one blob and sticking it into a characteristic...

I am designing a product with the nrf8002 chip and have a question on Power consumption. Lets say I leave all the default ratio's alone and use a CR1620 battery which has...
How can I read the Bluetooth clock (piconet) which is synchronized between the master/slaves in the piconet ? I need a constant (micro second accuracy) time from when I do...
Hello,
Is it possible to know the preamble , data format and the CRC calculation to interface a radio system ( GFSK Manchester) with NRF905 ?
Thank you
I'm wondering if the port and pin function can be used together to configure a set of pins.
For _port_dir_set, I assume it sets the whole port to the designated direction...
Hey i was using the code from developer.mbed.org/.../main.cpp
I am using this chip ( http://i.imgur.com/q8EM4uq.jpg ), it is nordic nRF51822 but i exactly do not know its...
I am using spi_master.c for spi communication with nRF51822EK.
