Overview

Every BT730 series Bluetooth module from Laird is designed to add robust, long-range Bluetooth data connectivity to any device. Based on the market-leading Cambridge Silicon Radio (CSR) BC04 chipset, BT730 modules provide exceptionally low power consumption with outstanding Class 1 range via 18 dBm of transmit power. A broad range of Bluetooth profiles such as Serial Port Profile (SPP) and other vital features make BT730 modules superior to other Class 1 Bluetooth modules. Available in BT730-SA and BT730-SC variants.

FAQ

How do I enable Multipoint on the BT730?

S Registers need to be set on the Ezurio Terminal to enable Multipoint mode on the BT730. To do this, follow these steps:

 

Start Ezurio Terminal

Enter “ATS127=0x200” (this will enable Multipoint mode)

Enter “AT&W” to save/write your settings

Power cycle the BT730 then start the Multipoint Terminal

Additional information on Multipoint can be found in Chapter 2 of the Firmware User Guide.

What is the throughput of your bluetooth modules with the embedded AT command interface?

Our fully-embedded modules have a throughput of around 300-360 kbps.  They have an on-board Bluetooth stack and do all of the Bluetooth processing themselves. Bluetooth 2.1 + EDR has a practical transfer rate of 2.1 Mbit/s, but this is not possible on a small embedded module that does not have a powerful PC-type processor.
