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...
Hello,
my application has to emit measurements in the manufacturer specific data structure continuously and has to accept a connection, for example for ANCS. Therefore...
Hi,
I am developing a firmware using nrf51822xxaa s130 SDK 10.0. I am using device manager to exchange the security keys and storing the bond information. For my project...
Hi, If I understand correctly the debugger on PCA10040 can operate in 6MHz/n as SWO frequency.
the nrf52 can operate at 4,8,16,32MHz swo frequency.
How are we to use SWO...
I am using SDK_11 s130 on nrf51-dk. When err_code is any value other than NRF_SUCCESS, APP_ERROR_CHECK(err_code) will cause nRF51-dk board to reset. How can one get APP_ERROR_CHECK...
I'm trying to implement the DFU Feature into my application, but it seems to be in a bootloop after it starts advertising.
The application works fine when flashing it via...
Hello everyone, I want to measure Low power mode current consumption in nRF52 DK,but I dont have accurate CRO to measure in micro Amperes, therefore I would like to know if...

Hi,
I am working on one project in which I want to connect my two custom borads with S130 softdevice but I am not able to do that. My custom board has nRF51822 chipset...
I would like to implement a simple code to use SAADC on NRF52 to sample one channel at maximum sample rate (theoretical 200KHz).
All the examples I have found use limiting...
Hello All,
At a time either ble nus or dfu can work.
I have an problem with the services ble nus for uart and dfu does not work simultaneously means if i am adding both...
Hey, I got 2 beacons which I have connected via BLE successfully however I have some problems with BLE_GATTC_EVT_HVX event. Every time I get only one BLE_GATTC_EVT_HVX event...
