Features


  • Bluetooth protocol: Bluetooth Specification V4.0 BLE

  • Working frequency: 2.4 GHz ISM band

  • Interface way: a serial port

  • Open environment within 30 meters can realize communication between modules

  • To send and receive no byte limit between modules

  • Modulation method: GFSK (Gaussian Frequency Shift Keying)

  • Transmission power: - DBM, 23-6 DBM, 0 DBM, 6 DBM, can be modified by the AT command

  • use TI CC2541 chip, configuration space of 256 KB, support the AT command, the user can according to need to change the role (master, slave mode) and the serial port baud rate, name of equipment, matching parameters such as passwords, use agile.

  • power supply: + 3.3 VDC 50 mA

  • working temperature: - 5 ~ + 65 Centigrade
