Bluetooth v4.1 ual Mode RS232 Serial Adapter Revised 13/MAR/2018 atasheet Version 46.3mm 1.0 16mm 34mm Features World s smallest Bluetooth Serial Adapter Low Power Consumption Bluetooth v4.1 specification (ual Mode) Applications available including SPP with GAP Central, SPP or GAP Peripheral and SPP to Serial Bridge Serial (RS232) interface 46.3mm x 34mm x 16mm Powered by USB or Pin 9 F E / CE (Master / Slave) mode switch R / SR Handshaking and RS / CS Flow control lines Over-the-Air Upgrade (OU) available Configurable with A Commands Application firmware support RoHS, REACH and WE Compliant Solution See our website for this products certifications Full uplex for simultaneous communication between sender and receiver Configurations pre-installed on production Overview he is the world s smallest Bluetooth serial adapter (RS232), providing a secure and reliable Bluetooth v4.1 connection. esigned to replace RS232 cables between a master (E) device and slave (CE) devices such as printers, data loggers and digital signalling devices. his standalone adapter incorporates a microcontroller unit with an 8 Mbit flash memory for running the application.he firmware controls the RS232 signals, including R / SR handshaking and RS / CS flow control lines. he A Command set is used to change the configurations, plus the developer can also configure and modify the settings of a remote from a local. Customised configurations and settings can be preloaded to the, simplifying the manufacturing and testing process. We also offer Bluetooth ual Mode applications, which can be customised to your specification. he module can be used as a bridge between Bluetooth v2.0, 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. Page 1 of 9

Bluetooth v4.1 ual Mode RS232 Serial Adapter Firmware he Bluetooth ual Mode module is configured by using A commands in configuration mode. he A command set controls the primary operations such as information enquiry, connection/disconnection set up and settings. he module can be configured via its UAR interface from a microcontroller or computer, using MCU software or a serial terminal (e.g. Hercules SEUP utility) respectively. At the start of every power up cycle the enters the configuration mode. efault Factory Settings evice Settings When the is connected to another Bluetooth device it enters into data mode. In data mode, users can send/receive data between the module and the remote device via UAR. o exit data mode, the user can use the escape sequence. If the responds with OK to the escape sequence it enters into the online_command_mode (i.e. the connection is still active, A commands can be entered via UAR or the connection can be dropped). he can re-enter into data mode by using A commands.
