General Details

Introduction of BLE Modules

USR-BLE100 is an ultra-low power V4.1 bluetooth module. It is used for point-to-point data transparent transmission. User’device can communicate immediately after simple setup without concerning about transport protocol. The module supports master and slave mode. User not only can use both master and salve for transparent transmission, also can develop APP on the basis of standard BLE protocol. The module supports one-to-many broadcast, and has built-in iBeacon protocol. User can make it an iBeacon equipment with simple setup.

Features of BLE Modules

  • Support standard BLE protocol
  • Low power broadcast mode of 1.3uA, sleep mode of 150nA,a variety of wake-up methods
  • Master/slave mode, quick switch
  • Setup methods: serial AT command,transparent transmission AT command
  • Support one-to-many data broadcast mode, built-in iBeacon protocol
  • Support Mesh networking mode to realize bluetooth self-organized network
  • Support UART Interface
