Hi, is there an available developer in my tri-state area of Minnesota, N. Dakota, or S. Dakota? Please call me if you are available for a project for hire. The developer should...
I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi, I am working on a project where I want to make one nrf51288 chip as central hub and connect that to a android phone and other salve nrf51288 .
idea similar to this: ...
Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
I've modified the ble_app_uart example by adding GPIOTE so that the transmitter sends a character to the receiver when a GPIO pin is toggled. This part is working well.
...
Hi,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
Hi,
I'am having an issue with UART using app_uart_fifo.c (SDK 0.9.2). At times I get communication error (usually at attaching and detaching uart connector) and my error...
Hi.
I'm little worried about our bt sensor power consumption.
We are using twi/i2c to communicate with sensors periodically. We are using app timer to trigger these...
I have a custom board that doesn't use the external 32Khz crystal. The engineer that designed it chose to use P0.0 as UART RX. (I know, poor choice.) I have set up a custom_board...
I am using SDK_11 s130. I see APP_ERROR_CHECK(err_code) being used throughout the SDK examples. When err_code is any value other than NRF_SUCCESS, the nRF51-dk board will...
Previously, I was able to program ble_app_uart using SDK_11 s130 into nRF51-dk. Now, I would like to program ble_app_uart into Adafruit Bluefruit LE friend board. www.adafruit...
I have been following the advertising tutorial and decided to start my own application using nordics git repo as a reference. After a few debug sessions I found that I needed...
I am trying to probe sysclk signal on one of the unused GPIO pins on a nRF52 board. I modified the ble_app_template example provided in SDK 11.0.0 and added a sysclk function...
I am trying to connect nRF52 with 7120 and create a NFC card reader , is this a solution and power efficient solution .
I will interface through I2C , is there a example...
I am using the sdk version 11 and arm-none-eabi-gcc version 5.4 on linux mint to compile the blinky test application. I have pointed the Makefile-posix at the location of...
I am doing the test about timeslot with the project link text
but it cannot scaninng and i found the timeslot is work because i get event NRF_EVT_RADIO_BLOCKED and it call...
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...
