Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

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,
I want to run a mesh application. Can you please tell me the most preferred ide for running mesh examples.
1.segger ide

Kindly tell me which one is...
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...
Hi, devzone
I tested nrfutil6.1.0 dfu ble feature and pca10040 as host board to upgrade another board pca10040, successful!
