Today, I tried out the Ble Bootloader from the Sdk examples.
As a central client, I'd used the »nRF Loader App« an an iPhone and also »nRF Mcp« on an Android Tablet.
I...
Hi,
from Keil uVision I need to debug/program nrf51822 in my application which uses 1.8 V. I guess nrf51 DK is not capable of doing this (it supports only 3 V targets). What...
Hi,
I have a reset issue when trying to set a delay greater or equal to 100 milliseconds using nrf_delay_ms(...). This only happens if I start my app timers (app_timer_start...
Hi,
I am trying to generate a 128Hz sine wave using the nrf_pwm library . First I tried this with SD110 enabled but ran into some problems that turned out to be a known...
Hi,
I'm going through the errata and a few of them look serious that the developer kit might be useless for some of us if we want to use it for any realistic testing (I...
I am trying to add a static passkey to my peripheral and protect from MITM. I tried the example nRF51-ble-app-uart-static-passkey but it doesn't seem to work correctly.

Hi,
I am new to nordic n51822, i have implemented adc and timer independently.
Now, what i want to do is read the adc values on a specific time when the timer overflows...
Received my nRF52 preview board yesterday and have been battling to get my S130 based nRF51 code running on it with the S132 soft device (the code is here: github.com/......
The codes i am using is
