CSRMesh is a mesh protocol developed to run over Bluetooth Low Energy. It extends the traditional Bluetooth Low Energy functionality and enables it to relay messages and broadcast over longer distances. The protocol creates a mesh from CSR SoC-based (CSR1010 and CSR1011) devices. This solution is very effective for a home automation system as it is not bound to a transmission range. CSR also markets its development kit, which helps in prototyping. Since it is a BLE-based device, you can connect through your Android, iOS, or desktop device. Here is the complete list of products offered by CSRMesh:

I recommend you buy a CSRMesh development kit that comes with at least three boards to make a full mesh structure.
Here is a view of a CSRMesh development board:
A CSRMesh development board comes with the following features:
- CSR1010 IC with EEPROM
- PCB antenna
- 1x RGB LED
- 2x buttons and 1x slide switch
- Power switch
- SPI programming connector
- 2x AA batteries
- I/O pads
- Temperature sensor
In 2016, Qualcomm acquired CSR, and it now sells CSR products while preserving the brand name. A list of CSR products can be found on the Qualcomm website, under the Bluetooth Products section
