BLE Scan Request Filter Demo

This blog is to show how to add the scan request filter on the BLE advertiser. In BLE (bluetooth Low Energy), basically, it has two difference modes on the scanning mode. On the BLE observer, it can be either passive scanning or active scanning. If the observer plays as the active scanning, it would send… Continue reading BLE Scan Request Filter Demo

How to get the RSSI change on the nRF5 SDK

This blog is to show how to get the RSSI (Radio Signal Strength Indicator) on the nRF52 chipset. RSSI In telecommunications, received signal strength indicator (RSSI) is a measurement of the power present in a received radio signal. RSSI is usually invisible to a user of a receiving device. However, because signal strength can vary greatly and affect functionality in wireless networking, IEEE 802.11 devices… Continue reading How to get the RSSI change on the nRF5 SDK
