Last Updated on：2023-01-30 09:44:43

1. The reporting and issuing commands of Bluetooth LE will be completed at the fastest speed. After the completion, the wireless transmission of Bluetooth LE will be suspended (but it is still under acceptaBluetooth LE status), which will be activated again for the next connection. In contrast, the connection of traditional Bluetooth is continuous.

2. There are only 3 Bluetooth LE broadcast channels (divided to ensure that the network does not interfere with each other). Traditional Bluetooth has 32.

3. Bluetooth LE only takes 3ms to ‘completes” a connection (ie, scans the devices, establishes links, sends data, authenticates, and ends properly). However, traditional Bluetooth requires hundreds of ms to complete the same connection cycle.

4. Bluetooth LE uses very short data packets, which are mostly used in products with high real-time requirements but low data rates. The categories such as remote control types including keyboards, remote mouses, and sensor devices, also heartbeat belts, sphygmomanometers, temperature sensors are availaBluetooth LE. Traditional Bluetooth uses longer data packets and can be applied for larger data transmissions, such as voice, music, and higher data transmissions.

5. Bluetooth LE has no power level. Generally, the transmission power is + 4dBm, and reaches a transmission distance of 70m in openning area. Traditional Bluetooth has 3 power levels, Class1, Class2, and Class3, which support 100m, 10m, and 1m respectively transmission distance.
