Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

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
nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_central_and_peripheral and nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_peripheral\ble_app_hrs
From the peripheral...
Just getting started with the PCA10001. I can compile if I select the device nrf51822_xxaa_s110, but when I load it tells me "can't load flash device description".
It subsequently...
I have take the basic ble_app_hrs_with_timeslot and modified it to calculate the timing of subsequent calls to the timeslot START event.
Specifically,
take note...
Hello,
I'm trying to get the new SDK up and running on my OSX machine. I would like to make the blinky example work on my PCA10003. So, I copied the blinky/pca10028 folder...
Hello, Do you guys know if it is possible to generate a stable 38kHz signal using the Nordic?
I have been able to generate the required frequency however I am observing...
Not a question but thought worth mentioning.

Good News
PWM library changes seems to have made it into the release.
Bad news:

Hello,
I am working on an nRF51822 custom board application which is reading data from external sensor through TWI. It is based on the MPU6050 driver available in the SDK...
Hi there,
Before I asked this question, I have searched similar question about TWI example, but it seems there were some guys looking for such example as well. Not sure...
Hello

I wonder if GPIO could safely be used for byte writes to the OUT port.
I have an 8bit (+control signals) peripheral connected to the GPIO and so far I was doing read-modify...
I will be using a 3.7V LiPo to power my NRF52 system. As far I understand, using the internal DCDC regulator is a better choice as it can save power compared to internal LDO...
