How can I extend the range of the BT510 Sensor?
The Sentrius™ BT510 sensors range is dependent on a number of factors some of which are under user control.
You can configure a sensor using a Bluetooth connection and the Laird virtual serial port(vSP) service. The protocol sent over the virtual serial port is JSON-RPC version 2.This allows you to add new commands and features without changing the Bluetooth interface.
This includes being able to configure
- Tx power
- LE Coded (Long Range) PHY
More details are available via the BT510 user guide.
It is also possible to extend the range of the BT510 using the Laird BL654 Repeater/gateway smartbasic programs this allows the Laird BL654 module to function as a repeater or gateway for adverts from Laird’s BT510 sensors. It can also operate in AT mode where it can advertise, scan, connect, and offer GATT client and server capabilities. This application is controlled with the industry standard AT command protocol over a UART interface.
- BT510 Repeater Mode–The module listens for adverts from Laird’s BT510 sensors or other BT510 repeaters and rebroadcasts over the air so that a range extension can be facilitated. All other adverts are ignored.
- BT10 Gateway Mode–The module listens for adverts from Laird’s BT510 orBT510 Repeaters and sends them out in hex format over the UART interface so that a host can process them. It could forward to the cloud if it has the appropriate connectivity. All other adverts are ignored.
- Generic BLE Client/Server Mode–The module can be made to advertise, scan, connect, and pair. In addition, it can enable the creation of a GATT server table on-the-fly and, conversely can be a GATT client to interact with remote GATT servers.
