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...
I connected my SEEED Ble Micro module via SWD to my nRF51-DK.
I then pressed ERASE ALL in the nRFgo Studio.
It worked. Now my Module is kinda empty. How to get stuff...
Following the instructions from the bluetooth sniffer guide, the sniffer code finds my device. I then attempt to launch wireshark (which has been installed) and I get a plugins...
I'm trying to download a HEX file to an nRF51822 using Keil and ULINK PRO. The hex file was generated by the mbed compiler and works if I drag and drop it using the programmer...
Hello devzone...
My setup: nRF51422 and S110 peripheral
My setup transmits IR data on reception of Bluetooth data from a central device. I have used PWM for generating IR...
I bought 5 Seeed Micro Ble Modules. On their Website they answered a question 7months ago, that they ship with QFAA G0. I connected them via SWD with my nRF51-DK.
God damn...
I am trying to decrypt some data.
My data is encrypted using AES-ECB No padding method.
I know the 32Byte key used for decryption.
Following is the code snippet. I am not...
I guess and hope not but I am a little confused by the compatibility matrix..
I would need to use SDK 7 or higher for my nRF51-DK
but I would need to use SDK6.1 or lower...
Hi,
I searched here for a while and I couldn't find the answer. I implemented custom service by referencing nAN-36 and the github code. For some reasons, the github code...
Hi there,
I am trying to generate a pulse on a pin using RTC1 and PPI. Using a TIMER this works fine but my goal is to incur minimum current consumption by using only the...
I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
In the sensor datasheet it says one can use SPI_Mode 0 or 3 (doesn't say that there is anything to do to switch between them).
I connected MISO from the DK with SDO from...
I want my application to cooperate with DFU. I am using example DFU project from SDK (6.1) (from nrf6310 folder, i simplified it so it could work on PCA10000), but i need...
I increased my IRAM1 size as advised here , but now my program doesn't work anymore on the nRF51 DK.
I know the problem is somewhere in the memory allocation, because when...
I am working with nrf51422 chips version 2, so according to this table taken from the compatibility matrix v2.0, the last supported versions of SDK/SD/SDS I should refer to...
Also it seems not to advertise. What may cause this problem?
All I could found in the ble_gap.h is:
If both conn_sup_timeout and
max_conn_interval are specified...
