BTM430 and BTM431 Series Bluetooth Module
Overview
The BTM430 and BTM431 Bluetooth modules from Laird have been designed to meet the needs of developers who wish to add robust short range Bluetooth data connectivity to their products. They are based on the market leading Cambridge Silicon Radio BC04 chipset providing exceptionally low power consumption with outstanding range. With a footprint as small as 12.5 x 18.0 mm for the BTM430 and best of class low-power operation these modules are the ideal choice for applications where designers need both performance and minimum size.
Note: The BTM430-xx variant has reached end of production and is available on a limited basis only. Only the BTM430 part numbers are affected. Find the End of Life Announcement in the Documentation tab below.

Documentation
CSR Bluesuite Bluetest3 crashes when trying to select the transport.
Bluesuite is a very old program supplied by CSR for testing and configuration of its legacy Bluetooth modules. Bluesuite Bluetest3 is often used for RF testing where the DUT is put into BCSP mode before running Blutest3.
If Bluetest3 crashes with an "array" error you may have a conflict or issue with your .net installation. You may be able to fix the issue by removing all versions of .net but please speak to your IT department first as this may cause issues with other software.
Is it safe to run a Ezurio 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.
Why isn’t a firmware upgrade available for the BTM43x?
There is no firmware available for download for the BTM43x as it has been very stable for the past few years. All of the BTM43x modules that were manufactured after November 1, 2010 should arrive pre-loaded with this firmware (v11.28.1.0). Version 11.28.1.0 is a comprehensive release of all previous features and bug fixes and is the default firmware loaded at production for all BT v2.0 AT modules. You can check the firmware version of your module by entering the "ati333" command in your terminal.
