Hi,
We designed the circuit followed the reference circuit(QFN48), but we always failed in the 8kv ESD test.The CPU always reset while ESD testing.
The 8kv ESD power...
Does anybody got an app inventor2 "project" to communicate with the (Adafruit) Bluefruit LE UART (or SPI) ?
Note: my Android version is 4.4.2 (LE "advertising" not supported...
I've created a Secure DFU client using the multilink central example with S130 and SDK 12.2 (running on PCA10031).
There are a few issues we have trouble with.
The...
Hi,
After successfully managing to preserve our devices bonding information (and custom app context data) across DFU updates, we have a few related questions.
I should...
In this blogpost we will demonstrate the usage of Keils integrated command line functionality. We will start nrfjprog through Keil bindings in order to erase our chip and program SoftDevices.
nrfjprog…
Bluetooth LE is a fantastic technology for battery powered, Internet of Things devices. However, most dev kits require tethering to a smartphone, limiting the range and usefulness to only when the user…
