Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
Hi,
I've followed the instructions to apply the free Nordic license for SES but it doesn't seem to like the MAC address. You can see from the attached images that the MAC...
Hi
My device is a medical device, we are now beginning verification. One of the items on the spec requires verification that 128bit AES is used during post-bond comms with...
Hello,
I have developed a small sensor which consists of MAX30101 HR sensor and nRF52832. For the research purpose I created an app as well which shows the raw data sent...
Hi,
I am selecting a Bluetooth IC based on the availability of true randomness in it and the nRF52832 is in the list.
"The Random number generator (RNG) generates true...
Hi,

Hi,
I'm evaluating the nRF52840 using the DK. I find that the hfxtal in the 52840DK is GSX-223, which is not included in the data sheets characterization of HFXTAL ramp...
Hi, I'm developing a wearable fitness device. The device collects accelerometer-gyro data and sends it to the mobile application. Initial developments are good, I created...
I'm using the <TWI Scanner> example. I use an oscilloscope to measure the signal of SCL (see image)
According to the datasheet, I'm connecting a 4.7K resistor to connect...
I am using the two units talking with each other for the BLE uart.
One is running with the example ble_app_uart_c_central. The other is running with the ble_app_uart_peripheral...
Setup:
Node: 1 nrf52840dk acting as a node flashed with mqtt_client_publisher running on top of OpenThread using the nrfSDK for Thread and Zigbee.
Debugger access via...
How are the pins of the nRF52840 used in the Nina B301 mapped into the Arduino / mbed os system? Using the pin mapping files in the ARduino code often doesn't seem to work...
Background: we have a nRF52832 based design that's been used for the past 1-2 years across a couple 100 piece batches. Our latest batch of 500 boards shows an odd behavior...
Hello all,
I'm using a nrf52840 and it's working fine. However, when I supply the chip with 5v on VDDH the GPIO output voltage is 1.8v. When I supply the chip with 3.3v...
Hi,
We are trying to use an nRF21540 FEM with nRF5340 running the latest nRF Connect SDK. Please can you advise how we can generate the necessary TX_EN/RX_EN signals to...
