  • Description

    Our LM048 Bluetooth® Serial Adapter uses a CSR IC which runs LM's own AT Command firmware, enabling connection to other Bluetooth® devices. The Bluetooth® Serial Adapter has been certified to use the Bluetooth® v2.1 + EDR or v2.0 + EDR. The firmware within the LM048 Bluetooth® Serial Adapter allows all of the known serial configurations to be used and it's this flexibility that has enabled LM to patent it's firmware. The AT command firmware which controls the RS232 signals (DTR, DSR, RTS, CTS) for line handling (which offers the full range of serial combinations) is easily configured by using the adapters slide-switch, on the top of the adapter. Our LM149 Configuration Software allows users to adjust various serial settings such as flow control, stop bits etc. It also enables users to update the device name and turn on or off Bluetooth® functions such as Auto Connect or Bluetooth® discoverable features. Please see the Software Tab above to download the correct Configuration Software version LM Technologies has built such applications within Android, Blackberry, Windows, macOS platforms, which enable the LM048 a range of smart phone solutions. These solutions can be developed for your own application free of charge by LM Technologies, when volumes in excess of 1000 pieces per annum are requested. Please see our case studies for further details on how the Bluetooth® Serial Adapter has be used in solutions.
