BLE Advertising Primer
The 2.4GHz spectrum for Bluetooth extends from 2402MHz to 2480MHz. LE uses 40 1MHz wide channels, numbered 0 to 39. Each is separated by 2MHz. Channels 37, 38, and 39 are used only for sending advertisement packets. The rest of the channels are used for data exchange during a connection. Weâ€™re interested in whatâ€™s happening in these 3 channels, and thatâ€™s what weâ€™ll cover here. Itâ€™s important to n
