Transcription

1 Features Bluetooth v2.0 + EDR and v2.1 + EDR compliant firmware available Class 2 radio with integrated chip antenna - 25 m range in open space Lead Free, RoHS compliant Small Size: 15.24mm x 27.67mm x 3.2mm AT Command set provided for module configuration Low Power Consumption Secure Simple Pairing supported (in Bluetooth EDR firmware) Applications operation SPP firmware supported by default. HD firmware available upon request Full Bluetooth EDR data rate of up to 3Mbps supported CSR Bluecore 04 (BC04) chipset nterface: (up to bps), P AT Command set provided for module configuration Multipoint firmware support Lead Free, RoHS compliant SPP firmware supported by default. HD firmware available upon request Small Size: 15.24mm x 27.67mm x 3.2mm CSR Bluecore 04 (BC04) chipset verview is LM Technologies Ltd Class 2 Bluetooth Data module with an onboard chip antenna. This module is a CSR Bluecore 4 (BC04) chip based surface mount module available with Bluetooth Serial Port Profile (SPP) firmware. This module is ideal for adding short range wireless connectivity to embedded products. The module acts as a standalone unit (ie: it does not need a host to drive it) and can interface with embedded micro-controllers via. t operates over a wide voltage range of 3.3 to 5 and gives excellent performance over a distance of 10-25m. This module is available with Bluetooth EDR as well as Bluetooth 2.1+EDR compliant SPP firmware. The module also comes with Bluetooth EDR compliant HD Keyboard firmware which is available upon request. Page 1 of 5
