Waveshare Dual-mode Bluetooth to TTL Serial Board - Blue
Dual-mode Bluetooth to TTL serial£¬ master/slave-in-one ?Overview: Dual-mode Bluetooth is a wireless module that allows bi-directional transparent data transfer between the TTL serial and Bluetooth devices. It is designed to be master/slave-in-one£¬ also£¬ it supports iBeacon. You can easily operate the module via AT commands£¬ like: set baud rate£¬ change broadcast name£¬ and IO control£¬ etc. Features: Dual-mode Bluetooth£¬ completely compatible with iOS and/or Android devices; Works as a full-duplex serial pipe after pairing£¬ requires no Bluetooth protocol knowledge; Fully configurable via AT commands XBee interface; Comes with iOS and Android demo code£¬ like: mobile robot remote control£¬ data acquisition£¬ device status monitoring£¬ etc. Specifications: Bluetooth version: Bluetooth Specification V4.0 EDR and BLE; Frequency range: 2.4GHz ISM; Modulation: GFSK (Gaussian Frequency Shift Keying); Communication distance: SPP 50m£¬ BLE 100m (ideal condition); Sensitivity: ≤-84dBm (0.1% BER)Antenna: onboard antenna; Transfer speed: about 40% serial speed for SPP£¬ about 30% serial speed for BLE; Packet length: 60 bytes for SPP£¬ 20 bytes for BLE; Serial buffer: 512 bytes; EDR service: L2CAP£¬ SDP£¬ RFCOMM£¬ SPP; BLE service: ATT£¬ GATT£¬ LE Service: 0xFFE0£¬ Char: 0xFFE1; Power consumption: SPP: avg 13mABLE: avg 9.5mA; Standard: 10~17mA; Power supply: 3.3V 50mA; Operating temperature: –5°C~80°C; Applications: Wearable devices; Bluetooth intelligent application; Smart home appliances; Industry control; Data acquisition system
