Hi all,
I've developed a broadband vibration energy harvester that is able to pick up uW of energy from just a couple Hz all the way to 150Hz. I'm currently looking for...

Hi
Im looking for a developer in Denmark to discuss ble technology with. Im trying to get better to understand the technology, because i have some ideas involving beacons...
This system does not work if I enable the third Pipe (Pipe2) .
The system is working without any problem as one RX and two TX (Pipe0 and Pipe1).
The problem on enabling...
Hello,
i have read if not all posts about writing to FLASH while using BLE. But could not find the desirable method.

Hi,
Are there any available examples of Makefiles with JLink command integrated?
Example: "make flash" to flash the image or "make flash-softdevice" to flash the softdevice...
It's not really a question but a request to Nordic.
Could you change the #ifdef lines in gcc_startup_nrf51.s to .ifdef. So:
.ifdef __STACK_SIZE
.else
.endif

Hello,
I receive NRF_ERROR_INVALID_STATE error quite a few times because my own state handling is still a little buggy. I want to find all these errors. What would be the...
Hi all,
Please I want to make sure of something. In the s120 specification, it's written " Bluetooth low energy combined Central and Peripheral SoftDevice", and even in...
Hello,
I need to read the UID and later on also the RSSI value of devices (Handys) in range.
It should be reading the values automatically without the need of manual connecting...
The datasheets for the nRF24LU1P ansd nRF24LO1P have near identical example antenna driver designs which vary in the values for the inductors, etc
The LU1P datasheet is...
Hi,
I've combined twi_sw_master and DFU in my project based on nRF51822 Beacon v1.1.0. Now I can't connect to the beacon. The same project only with DFU or only with twi_sw_master...
Error is shown in the following figure.
I use nrf51822-DK(256k)
