Bluetooth

Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices. Bluetooth low energy technology is the distinguishing feature of Bluetooth v4.0. u-blox Bluetooth low energy modules are designed for “Internet of Things” (IoT) applications, which require internet connectivity and extremely low power consumption. u-blox Bluetooth modules are suited for devices requiring a small footprint, low power consumption, and cost-efficiency.

Classic Bluetooth

Classic Bluetooth technology is typically intended for streaming data over short distances. The current Bluetooth specification states that it runs in the 2.4 GHz unlicensed ISM band using a master‑slave network topology and frequency hopping at 1600 hops/s. Its potential data rate is up to 3 Mbit/s. Due to frequency hopping Bluetooth is considered robust and is well suited to demanding applications.

Classic Bluetooth Technology Facts:

  • Range up to over 300 meters
  • Bluetooth v2.1+EDR (Enhanced Data Rate) with data throughput of 2.1 Mbit/s , latency of 5 –10 ms
  • Security features with 128‑bit encryption
  • High system density where several wireless devices can be connected in the same location
  • Robust features: Adaptive Frequency Hopping (AFH), Forward Error Correction (FEC), narrow frequency channels
  • Large installed base of products

Bluetooth Low Energy

Bluetooth low energy was designed for devices that do not stream data continuously but instead transfer small packets of data as needed. It operates in the 2.4 GHz ISM band using frequency hopping. The transmitter spends less time on the air and needs less energy when on the air. This, plus the fact that Bluetooth low energy devices can make connections very quickly, is the key to low power consumption.

Typical Bluetooth low energy devices are sensors, such as those used for monitoring room temperature, battery levels, and patient vital signs.
