Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
With there being +/- 4dBm variability in output power from nRF52 to nRF52, each device needs to be calibrated in order to comply with FCC rules. One of the rules is there...
Hi
I'm porting a nrf51822 project with S110 to a nrf52 board. In this case, I'm a bit confused about which softdevice to use. S132 it is the equivalent to the S110? Or...
Hello everyone,
I am using the nRF52832 rev 1, i am not using the softcore. When the cache is enabled as below, the performance actually seems to get worse.
