Hi,
We designed the circuit followed the reference circuit(QFN48), but we always failed in the 8kv ESD test.The CPU always reset while ESD testing.
The 8kv ESD power...
Does anybody got an app inventor2 "project" to communicate with the (Adafruit) Bluefruit LE UART (or SPI) ?
Note: my Android version is 4.4.2 (LE "advertising" not supported...
I've created a Secure DFU client using the multilink central example with S130 and SDK 12.2 (running on PCA10031).
There are a few issues we have trouble with.
The...
Hi,
After successfully managing to preserve our devices bonding information (and custom app context data) across DFU updates, we have a few related questions.
I should...
I would appreciate some suggestions on a good development flow to go from an Example to end application

I tested several sdk13.0.0 examples...
If anyone will ever have this error:
When using c++ and singleton the use of operator new is not possible.
I found the solution in this post: forum.arduino.cc/index.php...
I'd like to control a DC motor using PWM (PWM0, pretty straight forward).
To determine motor speed I disable the PWM every 5ms (TIMER1, pretty straight forward) and measure...
Hello,
Our application consists of 100 BLE static centrals and 1000 BLE moving peripherals. Is it possible to hide our BLE peripherals to be visible only by our centrals...
Hi,
i'm testing an application on nRF52, with nRF5_SDK_11.0.0-2.alpha and SoftDevice 132.
I took the ble_uart example and added a custom service with some characteristics...
Hello,
i'm trying a bluetooth connection between nrf UART v2.0 installed on my phone(android 4.4) and nRF 8001 (i'm usign nRF2740 card). My microcontroller is a STM32....
Hi.
I made my own board using nRF51822AC.
I want to connect this board to PCA10028.
There is Debug OUT port(P19).
Net names are EXT_VTG, EXT_GND_DETECT, EXT_SWDIO, EXT_SWDCLK...
Hi.
I'm using PCA10028, SDK10.0.0, S130.
Example code is using "ble_db_discovery_start()" function to discover peripheral.
In this function, there is "SRV_DISC_START_HANDLE...
Hi. I'm using PCA10028, SDK10.0.0, S130.
I'm testing External interrupt.
Current concumption was just 50uA around(low speed advertising mode).
But It goes 1mA around...
Hello
I'm working on a network of nodes with more than 300 nodes
each node is constructed by (1 arduino nano,humidity sensor, 1 relay and NRF24L01 +)

Hello. I'm trying to understand twi_sensor sample code on nRF51. (nRF51_SDK_10.0.0_dc26b5e\examples\peripheral\twi_sensor)
I have a trouble finding where the function twi_handler...
Hey,
i've bought the nrf52832 Preview DK some time ago, are there any big changes to the new DK? So if i buy a new nrf52832 IC i can desolder the old IC and use the new...
If I have some value and this value has become out of desired range I want to change property from indicate to notify.
I only found function sd_ble_gatts_characteristic_add...
I'm developing an application for a device which needs to support both DFU and some method of restricting connections to a single central (ie: bonding). This is a challenge...
