BT730 Series Bluetooth Module
Overview
Every BT730 series Bluetooth module from Laird Connectivity 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.

Documentation
Is it safe to run a Laird Connectivity Bluetooth module through a PCBA wash cycle?
In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed with any cleaning process.
- Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and the module. The combination of soldering flux residuals and encapsulated water could lead to short circuits between neighboring pads. Water could also damage any stickers or labels.
- Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the RF shield, which is not accessible for post-washing inspection. The solvent could also damage any stickers or labels.
- Ultrasonic cleaning could damage the module permanently.
However, if water washing is required you will need to use deionized water. We do not recommend chemical cleaning and cannot guarantee it will not damage the modules. If you MUST clean PCB with chemicals it is recommended that you test on one board and then confirm the module still works after the process, prior to adding it to production, while understanding the above affects washing the populated PCBs can have on the module.
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.
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.
