Hi
I'm doing project called automation of lights using beacons and iam using sdk (nRF5_SDK_12.1.0_0d23e2a) and nrf51822 dongle. I need complete information about advertising and scanning intervals of beacons ,at how much frequency does it takes to advertise or scans the beacons.can u please send me the information.
Hi,
BLE uses the 2.4Ghz ISM band, and uses 40 different RF channels in this band. 3 of these channels(channel 37,38 and 39) are used for advertising. You can see the frequency for the different channels in the image below. When you do a scan, these are the 3 channels that will be scanned. If you use one of the central examples in the SDK, you can specify the scan interval (from 2.5ms to 10.24s) and scan window (2.5ms to 10.24s) you want the SoftDevice to use.
