Bluetooth® 5.0 Dual Mode Module – LM074
LM offers firmware development support to assist with bespoke solutions. The LM074 Bluetooth® 5.0 Dual Mode module comes with a range of firmware for quick deployment. Firmware can be modified to meet your unique requirements or used for evaluation purposes. Available Applications SPP with GAP Central provides the flexibility of 1 SPP and up to 5 GAP Central connections simultaneously. SPP defines the setup of virtual serial ports for wirelessly connecting two Bluetooth (v1.0 – v3.0) devices; where the LM074 is set as the master (DTE) or slave (DCE) role. An ideal solution for wirelessly replacing RS232 serial cables. The module also supports “modem” command for the RTS/CTS/DTR/DSR lines. LM074 is defined as a GAP Central device for initiating Bluetooth low energy connections with nearby peripheral devices. Implemented with Over-the-Air Upgrade (OTAU) functionality for fast and convenient firmware updates. Users can read, write or modify data on the connected devices by utilising simple AT commands. It also supports a whitelist feature for Bluetooth low energy connections. Latest firmware version: 074LM_SPPC_0201Firmware Version Record for SPP with GAP Central SPP or GAP Peripheral allows the LM074 to run either SPP (Serial Port Profile) via Bluetooth (v1.0 – v3.0) or GAP Peripheral via Bluetooth low energy. SPP defines the setup of virtual serial ports for wirelessly connecting two Bluetooth (v1.0 – v3.0) devices; where the LM074 is set as the master (DTE) or slave (DCE) role. An ideal solution for wirelessly replacing RS232 serial cables. The module also supports “modem” command for the RTS/CTS/DTR/DSR lines. LM074 is defined as a GAP Peripheral device for accepting a Bluetooth low energy connection from master devices in range. It includes Over-the-Air Upgrade (OTAU) functionality for effortless firmware updates and SPP over GATT service for serial communication through Bluetooth low energy. Latest firmware version: 074LM_SPPPER_0105 SPP to Serial Bridge enables incompatible Bluetooth (v1.0 – v3.0) and Bluetooth low energy devices to communicate via LM074. The application is implemented on top of the CSR dual mode stack that provides the flexibility to communicate with any Bluetooth device. A simple AT commands set is available to establish and control the two simultaneous connections that form the bridge between a Bluetooth (v1.0 – v3.0) and a Bluetooth low energy device. It also supports simple secure pairing for Bluetooth connections, a whitelist feature for Bluetooth low energy connections and SPP over GATT service for serial communication through Bluetooth low energy.
