I've used the very well written IOT examples with no problem on a R PI, Ubuntu PC, and BBB all with 3.18 or 3.19 kernels. I've moved to 4.1 and 4.2 kernels and the behavior...
Does Nordic have an example iOS app that gets triggered by the beacon without having the app open?
This is really one of the main needs in beacons applications. Thanks!
Hi, the document nRF6930_Beacon_Ref_Design_UG_v1.1.pdf states:
4.2 nRF Beacon app for Android
The nRF Beacon application is available for download in the Google Play store...
Hi there!

When I debug it with JLink, the application...
Hello,
I'm wondering if it is possible to use the Bluetooth without using the scheduler.
Indeed, I'm developping an application which doesn't use Bluetooth up to now,...
Hello,
I am programming nRF51 on Keil. My app uses BLE with softdevice S130, PWM, and I2C communication with two sensors. Also RTT for debugging.
I have already reached...
Hi there!
I use RedBearLabs Nano (nRF51822) for at setup where I've developed BLE code in Arduino to communicate with apps on both iOS and Android.
Now I need to ensure...
Hello,
We recently received an eval kit the the nRF52832, but we were told not to take current measurements with this version. This presents a problem since we are evaluating...
