Exchanging Data Wirelessly with Bluetooth LE and ZigBee
summary
Python connects to Bluetooth LE using the btle library and BlueZ-like tools, discovers device MACs, reads service UUIDs and characteristics, and must enable notifications to get async replies under a 20‑byte MTU; a simple Peripheral + delegate demo repeatedly drops about half the packets in the basement. ZigBee (802.15.4 xB series) uses an FTDI serial modem with +++ command wake, 9,600 baud and a 100‑byte MTU, and the custom struct/serial Python protocol reliably delivers temperature/humidity packets to a Raspberry Pi.
