I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
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

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,

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 try make a firmware update with nrf toolbox for iOS and i have a popup with "Please enable Service Changed Indication in your firmware".

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...
