After the release of nRF52840 Engineering B we have received several inquiries about the difference between Engineering A (nRF52840-QIAAAA) and Engineering B (nRF52840-QIAABB) reference designs. One reason for the inquiries is that after swapping Engineering A with Engineering B samples customers experienced that the radio stopped working. The symptoms being that everything but the radio seemed to work in their application. While this is highly unfortunate, it is to be expected because there was a vital d...

In mid-2017, I came across this project by James Munns. It essentially wraps the C SDK for nRF52 development boards, and provides bindings that can be called from Rust. James gave a talk to the Rust DC Meetup, remotely over video conference. This talk inspired me to buy a couple of nRF52 dev boards.I'd like to announce that here, in Nordic's official channels, because I'd like more embedded developers to become aware of it. Rust is a language that has the ability to compile down to native code with zero r...

I've been looking for an excuse to write a low-latency, Enhanced ShockBurst (ESB), radio protocol that I can reuse when building remote control toys. Although Bluetooth is great for a lot of use cases, working with the Nordic radio's proprietary mode offers additional flexibility -- in this case, this means achieving lower latencies and streaming packets in a UDP-like manner (versus BLE's reliable transport). I recently found an opportunity to scratch this item off my list when the girl agreed that it wou...

Hi,I am developing application using nRF52832, s132, sdk13.2 which is collect sensor data and sent it to server. I have sent data to server using nRf52832 and interface with wifi module via UART. Now problem is i want to configure WiFi module credentials using BLE with android app, when i connect BLE to android app and sent wifi credentials to nRF52832 chip store it in one buffer and OFF BLE trying to switch this same UART for WiFi communicating. But at this time my hardware is reset and this credentials ...

Hello,we have a problem using the SAADC module with the low power mode, particularly after execution of the NRF_SAADC->TASKS_SAMPLE task.Before taking a sample, the current consumption in lower power mode is around 2.3 uA. After sampling and disabling the SAADC module the current consumption stays at 460 uA in low power mode and can only be reverted to 2.3 uA after a reset.What could be causing this behavior?We're using the nrf52832 Chip with the s132 Softdevice....

Hello,I have question about signal names in datasheet nRF52840.On the pins B19 and T2 on page 14 both pins have the same initial signal names (P0.11).Please send me answer and corrected document on my email: artur.bielinski@dynamic-precision.com.Best Regards Artur BielinskiComponent Engineerwww.dynamic-precision.com...
