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...

My question...
Solved: Well, turns out delay and SCK doesnt work well together haha. I imagined the sck signal to be a background thread of some sort. I was wrong.
Hi guys,

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'm using JLinkEXE to flash an nRF51822 chip. When I use nrfgo and press "erase all", it wroks. But after if I flash the s130, I can't erase the s130 with command...
Currently I have a few characteristics which are Authorized Read and Writes. Upon detected of the Authorization from the Central I trigger a few events such as:
Measure...
Hi !
I'm using an nRF52 on PCA10040 board and nRF5_SDK_11.0.0_89a8197. I want to run the peripheral ble_app_template with SEGGER Embedded Studio v2.20. I correctly set...
In an effort to try and determine why FreeRTOS tickles idle is consuming more current than tick mode with an idle task, see this post devzone.nordicsemi.com/.../ , I noticed...
Hi, i am designing a board using nrf51822 and planning to use a MOSFET for reverse battery protection instead of a schottky diode or a normal diode. I am new to this and learning...
I'd like to read and write data to the reserved app data space while in the bootloader. Is this possible with pstorage?
Because the BOOTLOADER_SETTINGS_ADDRESSS = 0x0003FC00...
Hi,
I'm developing a nRF52 application that exploits two ADC channels in single ended configuration.
VDD is 3.0V.
For the signal conditioning I've chosen a driving Op...
I've been trying to get my head around using a BLE central and making connections so I've loaded up the multi-central example to figure out just how everything works. I turned...
Hi everybody!
I am working with ANCS (nrf51822 SDK 9.0) I am confusing on setting the connection parameters which are MIN an MAX connection interval.
Firstly, I set...
Hello,
I have some characteristics on my device that are containing some configuration data.
Every single variable is a global variable.
The values can also be changed...
I am using the nRF51822 bluetooth low energy smart beacon kit and am running into trouble using the GPIOs available on the board (pins 0, 1, 2, 3, 5, 9, 11, 20, 21, 24). For...
Hello Everyone,
I am trying to monitor my battery voltage on the analog pin (ADC) so inorder to do that i am going to use the voltage divider circuit to calcualte the R1...
