Hi,
We're working on a project using the nRF5340, where we interface an external NAND flash (4096 blocks) to store high-volume sensor data. We are planning to maintain an...
Hi,
We are currently evaluating the NRF9151 for asset tracking using the AT firmware on the NRF9151 evk and an external MCU for the application firmware, emulating the final...
Hello,
We’re Bachelor’s students developing a project to estimate the angle of arrival (AoA) using a BLE antenna array on the nRF52833. Our implementation builds on Zephyr...
I recently discovered this article ( mbientlab.com/.../) and am trying to understand the data transfer type between the firmware ( ble_app_hrs_s110_pca10028 ) and an iOS device...
Hi,
Currently when I run the HRM demo I end up in the app error handler, unfortunately the error codes don't print to my terminal window. I'm using crossworks, and I was...

Things I am concerned about...
Hi,
I am using the nRF51822 with an external chip. The nRF51822 has interrupts which trigger when one of the signals from the external chip goes low. When using BLE and...
My program does a lot of dynamic memory allocation and at some point "malloc" retruns NULL , which is cause the system running out of allocated heap memory (I am assuming...
Hi,

Is it possible to use the nRF51 dongle as a slave ?
I have a nRF51422 Eval board that I am planning to use as a central device. Can I use the nRF51 as a slave so that I...
Hello we have developed a few products which have required (costly) RF/RFPHY testing.
Is there a reference design that is qualified that can be used to avoid the RF/RFPHY...
Suppose a BLE central needs to get sensor data from 10 peripheral sensors. Given that there is a limit to the number of connections a BLE central can have, is it better for...
Has anyone managed to get this revision of the nrf8001 IC working?
i bought 280 of them and none of them seems to work as it should.
