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. ...
I want to build nrftoolbox app in android studio. I downloaded the zip file from the github website and also the required dfu library. I unzipped both the files in a folder...
Hello,
I am using the Thingy:91 PCB and I have disabled the nRF52 by cutting SB4 and soldering SB3. This makes me unable to log through UART. For this reason I implemented...
To the kind attention of Nordic support team,
I need to disable, enable gzll more times. When enabling it, code gets often stuck in my case as in figure: nrf_impala.c 442...
I have achieved Bluetooth connection between 1*ble_central<------>6*ble_peripheral.
But, ble_peripheral sometimes upload data at the same time, then sometimes lose data...
We're successfully using nrf_crypto_aead_crypt() with AES CCM, a 128-bit key, a 64-bit MAC, and the NRF_CRYPTO_ENCRYPT operator to encrypt some data and generate a MAC that...
HI, all,
I am trying to transfer my previous project from nrf51822 to nrf52840, and at very the beginning ,I can not make the UART/UARTE of nrf52840 work.

Hi, everyone,
I am pretty new to nRF52 development. Right now, I have an issue with the SAADC trigger by RTC, which I follow this example . The issue that I have right now...
Hey all,
Here's another question. Many of the examples in the Nordic Connect SDK are rather large. Transferring them with MCUmgr at 115200 BAUD takes sometimes more than...
Hi
I am testing sending and receiving data between nRF51 dongle and peripheral by example of heart-rate-collector.
now I could find characteristics I need(write, read...
Hi all,
My application is as follows:
I have an android app which will send some data to a nRF DK. The data I want to send is in HEX characters between 0x00 to 0xFF. And...
Hello,
For nRF51822 and nRF52832, I'm using GPIOTE, PPI and timers to measure the duration that a pin, which is normally low, goes hi (typically 100-300 milliseconds). I...
The following questions are in regards to the instructions at nRF_Connect_SDK-modifying-a-sample-application .
In the Windows environment, I am transitioning from using...
Dear all,
I recently made a custom PCB using the aQFN73 package of the nRF52840 and, even though I respected the antenna constraints (but in 2 layers) I get no signal whatsoever...
Hi Devzone:
I am using P0.00 as SDA and P0.01 as SCL on nRF52833, And I got waveforms like below when I am doing I2C transactions:
the red waveform is SDA and the green...
Hello,
I slightly modified examples\multiprotocol\experimental\ble_zigbee_dynamic_color_light_bulb_thingy so that it can receive changes in the color temperature attribute...
