Description
The LM068 is the world’s smallest Bluetooth® 5.0 serial adapter (RS232), providing a secure and reliable Bluetooth® 5.0 connection. Designed to replace RS232 cables between a master (DTE) device and slave (DCE) devices such as printers, data loggers and digital signalling devices. This standalone adapter incorporates a micro-controller unit with an 8 Mbit flash memory for running the application. The firmware controls the RS232 signals, including DTR / DSR handshaking and RTS / CTS flow control lines. The AT Command set is used to change the configurations, plus the developer can also configure and modify the settings of a remote LM068 from a local LM068. Customised configurations and settings can be preloaded to the LM068, simplifying the manufacturing and testing process. We also offer Bluetooth® Dual Mode applications, which can be customised to your specification. The module can be used as a bridge between Bluetooth® 5.0 and is backward compatible with 2.0, v2.1 and Bluetooth® v4.0, v4.1 devices, using our SPP to Serial Bridge application. We also offer SPP with GAP Central and SPP or GAP Peripheral applications. -
